+00:00:00,650 --> 00:00:07,470
+Hi, and welcome to the first of several lessons on tools of the trade. I'm
+
+2
+00:00:07,470 --> 00:00:12,200
+very excited about these lessons, because I believe that tools are a cornerstone
+
+3
+00:00:12,200 --> 00:00:14,390
+of the software engineering discipline, and it
+
+4
+00:00:14,390 --> 00:00:17,570
+is of paramount importance to know and
+
+5
+00:00:17,570 --> 00:00:20,330
+use them. In this lesson, we will
+
+6
+00:00:20,330 --> 00:00:25,530
+talk about integrated development environments, normally called IDEs.
+
+7
+00:00:25,530 --> 00:00:29,780
+And these are software applications that support developers in many of their
+
+8
+00:00:29,780 --> 00:00:36,870
+everyday tasks, such as writing, compiling, and debugging code. And to make the
+
+9
+00:00:36,870 --> 00:00:42,470
+discussion more concrete we will focus on a specific IDE, Eclipse. We will
+
+10
+00:00:42,470 --> 00:00:47,250
+first present Eclipse, and then get some hands-on experience through a demo.

+1
+00:00:00,160 --> 00:00:02,750
+As I just told you, tools are fundamental in
+
+2
+00:00:02,750 --> 00:00:06,050
+software engineering. And I will stress this concept over and
+
+3
+00:00:06,050 --> 00:00:08,240
+over, throughout the class. And today we're going to talk
+
+4
+00:00:08,240 --> 00:00:11,310
+about a tool that is especially important, which is integrated
+
+5
+00:00:11,310 --> 00:00:15,060
+development environments, or IDEs. And you're probably familiar with
+
+6
+00:00:15,060 --> 00:00:18,060
+IDEs. So IDEs are environments that give you support for
+
+7
+00:00:18,060 --> 00:00:21,580
+your development activities. For example, for writing code, editing code,
+
+8
+00:00:21,580 --> 00:00:25,320
+compiling code, and so on. And we will focus specifically
+
+9
+00:00:25,320 --> 00:00:28,890
+on one particular IDE, which is called Eclipse. And
+
+10
+00:00:28,890 --> 00:00:31,450
+what I'm showing here is the two splash screens for
+
+11
+00:00:31,450 --> 00:00:35,350
+two versions of eclipse, Helios and Kepler. Eclipse is an
+
+12
+00:00:35,350 --> 00:00:39,200
+open, extensible development environment that was initially created by IBM
+
+13
+00:00:39,200 --> 00:00:41,510
+and is now managed by the Eclipse Foundation. And of
+
+14
+00:00:41,510 --> 00:00:43,840
+course, there are many other great IDEs such as for
+
+15
+00:00:43,840 --> 00:00:47,310
+example, Microsoft Visual Studio or Netbeans. We will be using
+
+16
+00:00:47,310 --> 00:00:50,830
+Eclipse because it is open and because it is multi-platform,
+
+17
+00:00:50,830 --> 00:00:52,390
+which means that you can use Eclipse
+
+18
+00:00:52,390 --> 00:00:55,140
+no matter what operating system we're using.
+
+19
+00:00:55,140 --> 00:00:59,030
+So if we consider the most commonly used operating system, such as Mac
+
+20
+00:00:59,030 --> 00:01:02,780
+OS, Windows, Linux, Eclipse runs on any
+
+21
+00:01:02,780 --> 00:01:04,769
+of these environments. Therefore, no matter what
+
+22
+00:01:04,769 --> 00:01:06,490
+you're using, you'll be able to install
+
+23
+00:01:06,490 --> 00:01:08,560
+Eclipse, run Eclipse, and follow the class.

+1
+00:00:00,130 --> 00:00:05,680
+So, now let's look in a little more detail to what is an IDE. An IDE is a
+
+2
+00:00:05,680 --> 00:00:09,790
+software application that supports software developers in many of
+
+3
+00:00:09,790 --> 00:00:13,840
+their everyday tasks. It has many useful features. Most IDEs
+
+4
+00:00:13,840 --> 00:00:16,790
+provide views that can be used to navigate, project
+
+5
+00:00:16,790 --> 00:00:20,140
+resources from different perspectives. For example, you might want to
+
+6
+00:00:20,140 --> 00:00:22,390
+look at your code differently when you're writing code,
+
+7
+00:00:22,390 --> 00:00:25,950
+and when you're debugging. They also normally provide an intelligent
+
+8
+00:00:25,950 --> 00:00:29,380
+source code editor. For example, an editor that will allow you
+
+9
+00:00:29,380 --> 00:00:32,110
+to browse the documentation when you're writing a code that
+
+10
+00:00:32,110 --> 00:00:35,780
+uses a specific method, or that will give you autocompletion when
+
+11
+00:00:35,780 --> 00:00:37,990
+you start writing the name of an object and you want to
+
+12
+00:00:37,990 --> 00:00:40,820
+get the methods for that object. And all of these things
+
+13
+00:00:40,820 --> 00:00:43,420
+can be very useful while you're developing and can save you a
+
+14
+00:00:43,420 --> 00:00:47,750
+lot of time. Modern IDE's will also normally give you support for
+
+15
+00:00:47,750 --> 00:00:49,540
+version control systems that then you
+
+16
+00:00:49,540 --> 00:00:52,490
+can use for softer configuration management.
+
+17
+00:00:52,490 --> 00:00:55,720
+And we're going to discuss in detail version control systems in
+
+18
+00:00:55,720 --> 00:00:58,380
+the next tools of the trade lesson, and we're also
+
+19
+00:00:58,380 --> 00:01:01,135
+going to see how it can be integrated within an IDE.
+
+20
+00:01:01,135 --> 00:01:04,730
+IDEs also give you builders so they give you build automation
+
+21
+00:01:04,730 --> 00:01:08,070
+tools, they give you runtime support. So that you can
+
+22
+00:01:08,070 --> 00:01:10,960
+run your projects from within the IDE and, for example,
+
+23
+00:01:10,960 --> 00:01:14,550
+observe some aspects of the execution. In addition to giving
+
+24
+00:01:14,550 --> 00:01:17,562
+you support for the runtime, they give you support for testing.
+
+25
+00:01:17,562 --> 00:01:21,267
+Many IDEs allow you to run tests from within
+
+26
+00:01:21,267 --> 00:01:23,520
+the IDE and to check the results of the tests
+
+27
+00:01:23,520 --> 00:01:26,300
+from within the IDE. Not only that. Normally, after you
+
+28
+00:01:26,300 --> 00:01:28,210
+run your tests, if there are some test cases that
+
+29
+00:01:28,210 --> 00:01:31,500
+fail, you can also use your IDEs to do debugging.
+
+30
+00:01:31,500 --> 00:01:35,620
+Many IDEs include graphical debuggers. Debuggers will allow you to
+
+31
+00:01:35,620 --> 00:01:39,400
+navigate through the code, set which points, stop and restart
+
+32
+00:01:39,400 --> 00:01:43,160
+the execution. Inspect variables, and do all of the activities
+
+33
+00:01:43,160 --> 00:01:46,320
+that help debugging. And, to help you be more efficient
+
+34
+00:01:46,320 --> 00:01:49,440
+and more effective when you do debugging. And into addition to
+
+35
+00:01:49,440 --> 00:01:52,760
+all these features that are listed here IDEs can normally provide
+
+36
+00:01:52,760 --> 00:01:56,650
+you even more features through a mechanishm that is called plugins.

+In fact most IDEs are extensible through the use of
+
+2
+00:00:03,134 --> 00:00:06,158
+plug-ins. And by the way, note that plug-ins might be
+
+3
+00:00:06,158 --> 00:00:09,326
+called differently on different platforms. For example, if you're using
+
+4
+00:00:09,326 --> 00:00:12,970
+a Microsoft Visual Studio, plug-ins are normally called add-ins, but
+
+5
+00:00:12,970 --> 00:00:15,598
+the concept is more or less the same. So, what
+
+6
+00:00:15,598 --> 00:00:18,555
+is a plug-in? Well, let's imagine our IDE to be
+
+7
+00:00:18,555 --> 00:00:22,320
+this box. A plug-in is additional functionality that you can
+
+8
+00:00:22,320 --> 00:00:25,430
+actually plug into this box so that this box starts
+
+9
+00:00:25,430 --> 00:00:28,830
+offering more features to the user. For example, you
+
+10
+00:00:28,830 --> 00:00:32,850
+can add to Eclipse the Checkstyle plug-in. Which, paraphrasing the
+
+11
+00:00:32,850 --> 00:00:35,950
+Checkstyle website, helps you ensure that your Java code
+
+12
+00:00:35,950 --> 00:00:38,890
+complies with a set of coding standards by inspecting the
+
+13
+00:00:38,890 --> 00:00:41,690
+code and pointing out items that deviate from a
+
+14
+00:00:41,690 --> 00:00:44,870
+defined set of coding rules. Again, this is a functionality
+
+15
+00:00:44,870 --> 00:00:47,330
+the core of Eclipse doesn't have. You can add
+
+16
+00:00:47,330 --> 00:00:50,600
+the Checkstyle plug-in, and this functionality will become available in
+
+17
+00:00:50,600 --> 00:00:54,840
+the IDE. Another example of plug-in is the EGit plug-in which
+
+18
+00:00:54,840 --> 00:00:58,660
+adds support for the Git version control system in Eclipse. And
+
+19
+00:00:58,660 --> 00:01:01,290
+actually this is something that we'll cover in detail, we'll have
+
+20
+00:01:01,290 --> 00:01:04,150
+a demo, and we will actually use it throughout the class, so
+
+21
+00:01:04,150 --> 00:01:07,018
+I'm not going to say anything more about the EGit plug-in for
+
+22
+00:01:07,018 --> 00:01:09,300
+now. But again, what the plug-in will do is to add
+
+23
+00:01:09,300 --> 00:01:13,220
+the Git functionality to Eclipse. A functionality that is not in
+
+24
+00:01:13,220 --> 00:01:16,110
+the core of Eclipse and that is available to the user after
+
+25
+00:01:16,110 --> 00:01:17,181
+you add the plug-in.

+In the rest of this lesson we're going to look at eclipse and
+
+2
+00:00:02,550 --> 00:00:05,290
+try to get more familiar with eclipse in a hands on manner
+
+3
+00:00:05,290 --> 00:00:07,550
+through a demo. In the demo we will cover some of the
+
+4
+00:00:07,550 --> 00:00:11,040
+basic aspects of eclipse like how to run eclipse, how to select
+
+5
+00:00:11,040 --> 00:00:14,400
+their workspace, how to create a project, how to create the class
+
+6
+00:00:14,400 --> 00:00:18,240
+within the project and so on. I'll also cover some more advanced
+
+7
+00:00:18,240 --> 00:00:21,610
+aspects, like how to create builders, run your project within Eclipse, and
+
+8
+00:00:21,610 --> 00:00:25,800
+how to use their Eclipse debugger. So let's get to the demo.
+
+9
+00:00:25,800 --> 00:00:28,220
+So let's start Eclipse. Eclipse is going to ask me
+
+10
+00:00:28,220 --> 00:00:31,600
+for the location of my workspace and in this
+
+11
+00:00:31,600 --> 00:00:34,530
+case, I selected a suitable directory and you can
+
+12
+00:00:34,530 --> 00:00:38,480
+also use that checkbox on the left to avoid Eclipse
+
+13
+00:00:38,480 --> 00:00:40,640
+for asking you again about where to put the
+
+14
+00:00:40,640 --> 00:00:43,860
+workspace. And the workspace is basically the place the
+
+15
+00:00:43,860 --> 00:00:48,310
+directory. Where, Eclipse will place all of your projects.
+
+16
+00:00:48,310 --> 00:00:50,830
+So, now when you start Eclipse, if it's the first
+
+17
+00:00:50,830 --> 00:00:53,480
+time you might get this Welcome screen. It's not going to happen
+
+18
+00:00:53,480 --> 00:00:57,500
+again on subsequent executions, but I just wanted to make sure
+
+19
+00:00:57,500 --> 00:01:00,210
+that I covered all the bases. And so, whatcha want to
+
+20
+00:01:00,210 --> 00:01:03,360
+do here is to basically go to the java perspective
+
+21
+00:01:03,360 --> 00:01:06,760
+which you can do by clicking over there or you can
+
+22
+00:01:06,760 --> 00:01:09,240
+also use the menus. So in this case we will have
+
+23
+00:01:09,240 --> 00:01:12,810
+to go to Window, open Perspective, and if the Perspective is
+
+24
+00:01:12,810 --> 00:01:15,660
+not here, you'll have to click on Other. And at this point,
+
+25
+00:01:15,660 --> 00:01:18,030
+that you can click on Java Perspective, then you
+
+26
+00:01:18,030 --> 00:01:21,680
+click okay. And the perspective is basically, the visual work
+
+27
+00:01:21,680 --> 00:01:24,810
+space where you will be operating. So, after we selected
+
+28
+00:01:24,810 --> 00:01:29,350
+perspective, we can actually close the welcome screen. And here,
+
+29
+00:01:29,350 --> 00:01:32,000
+you see that you have this different areas and on
+
+30
+00:01:32,000 --> 00:01:34,930
+the left You have the package explorer. This is the
+
+31
+00:01:34,930 --> 00:01:37,650
+area where your packages will be, you've got a task list,
+
+32
+00:01:37,650 --> 00:01:41,280
+and an outline on the right which we'll cover later.
+
+33
+00:01:41,280 --> 00:01:44,870
+And then you have underneath, the bottom, a problems, java
+
+34
+00:01:44,870 --> 00:01:48,330
+doc and declaration views and we will see some of
+
+35
+00:01:48,330 --> 00:01:51,320
+these views in actions later. And here in the center
+
+36
+00:01:51,320 --> 00:01:54,290
+you have the area. Which is called a code editor,
+
+37
+00:01:54,290 --> 00:01:58,360
+which is where you'll be writing, editing, and modifying, basically,
+
+38
+00:01:58,360 --> 00:02:00,440
+your code. This is where most of the action takes
+
+39
+00:02:00,440 --> 00:02:03,140
+place. So let's start by creating a Java project. And
+
+40
+00:02:03,140 --> 00:02:06,950
+to do that we can use either the context menu, or
+
+41
+00:02:06,950 --> 00:02:09,560
+you can just use the menu, select new Java project.
+
+42
+00:02:09,560 --> 00:02:12,390
+You'll be greeted by this, wizard, and. And at this
+
+43
+00:02:12,390 --> 00:02:15,500
+point in the wizard, you can select the name of
+
+44
+00:02:15,500 --> 00:02:19,100
+your project. I'm just going to call it a very simple way
+
+45
+00:02:19,100 --> 00:02:21,990
+my project. And I going to use the default location for
+
+46
+00:02:21,990 --> 00:02:24,070
+the project, as you can see it will be placed
+
+47
+00:02:24,070 --> 00:02:27,440
+in the work space that I selected before. I'm going to
+
+48
+00:02:27,440 --> 00:02:32,080
+also use the default. Java Runtime Environment, which is Java 1.7
+
+49
+00:02:32,080 --> 00:02:36,250
+in this case. I'm going to keep the selected default layout
+
+50
+00:02:36,250 --> 00:02:39,120
+and the, then I'm going to go to the next step. Here,
+
+51
+00:02:39,120 --> 00:02:42,380
+we're first presented with the location of the source code for
+
+52
+00:02:42,380 --> 00:02:46,840
+our project. The default is a directory SRC in my project
+
+53
+00:02:46,840 --> 00:02:49,320
+and for the output file, the directory bin. So repeat, we're now
+
+54
+00:02:49,320 --> 00:02:52,410
+going to change that. Here in case you need other projects to
+
+55
+00:02:52,410 --> 00:02:55,240
+build your own, then you can specify them here. Here we
+
+56
+00:02:55,240 --> 00:02:57,570
+are building a simple project, so there's no need for that.
+
+57
+00:02:57,570 --> 00:03:00,890
+And here we can specify which libraries our project requires. As
+
+58
+00:03:00,890 --> 00:03:03,880
+you can see, the Java library's already specified. And you can
+
+59
+00:03:03,880 --> 00:03:07,840
+also add other jars, which can even be External jars. And
+
+60
+00:03:07,840 --> 00:03:11,840
+finally this is the tab that allows you to specify which
+
+61
+00:03:11,840 --> 00:03:14,300
+part of you project. So how your project will be exported,
+
+62
+00:03:14,300 --> 00:03:16,760
+so lets not worry about that for now. Lets click finish.
+
+63
+00:03:16,760 --> 00:03:19,300
+And as you can see here on the package explorer, my
+
+64
+00:03:19,300 --> 00:03:22,920
+project appeared. So now we can open the project by clicking
+
+65
+00:03:22,920 --> 00:03:24,920
+on the triangle right next to it, and as you can
+
+66
+00:03:24,920 --> 00:03:28,250
+see there is the SRC directory, where my source code will go,
+
+67
+00:03:28,250 --> 00:03:31,760
+and there's also an indication that we're using the JRE, so that's
+
+68
+00:03:31,760 --> 00:03:35,800
+the Java system directory within our project. And this is just for people
+
+69
+00:03:35,800 --> 00:03:38,860
+who are interested in what happens you know, under the hood. So
+
+70
+00:03:38,860 --> 00:03:41,840
+if you don't care about that, you can just skip this part. So
+
+71
+00:03:41,840 --> 00:03:45,200
+basically here I'm showing you how we can go to the directory
+
+72
+00:03:45,200 --> 00:03:49,250
+where the project was created. We can see the bin and src directories.
+
+73
+00:03:49,250 --> 00:03:52,020
+And there's also some other files here that you can
+
+74
+00:03:52,020 --> 00:03:54,780
+see these 'dot' files that you will not normally, see. And
+
+75
+00:03:54,780 --> 00:03:57,870
+those are kind of bookkeeping files. So these are files that
+
+76
+00:03:57,870 --> 00:04:02,280
+contain information about your project and that are created automatically by
+
+77
+00:04:02,280 --> 00:04:05,860
+Eclipse. And, for example, will have various indication about the
+
+78
+00:04:05,860 --> 00:04:09,580
+configuration of the project, some settings and the class path for
+
+79
+00:04:09,580 --> 00:04:11,880
+the project. And, as I said, you don't have to worry
+
+80
+00:04:11,880 --> 00:04:14,490
+about this if you just want to go Eclipse as you're never
+
+81
+00:04:14,490 --> 00:04:16,551
+going to mess with the command line.

+So now that we know, we saw what happens under
+
+2
+00:00:02,420 --> 00:00:04,570
+the hood, and as I said, don't worry about it if
+
+3
+00:00:04,570 --> 00:00:06,689
+you don't care about that part. Now we can go back
+
+4
+00:00:06,689 --> 00:00:09,850
+to Eclipse, and we can start creating a package. A package
+
+5
+00:00:09,850 --> 00:00:13,125
+is basically a way of organizing your classes into a
+
+6
+00:00:13,125 --> 00:00:17,015
+hierarchy. In this case, I'm going to specify the package name as
+
+7
+00:00:17,015 --> 00:00:21,350
+edu.gatech, which means that I'm creating really two packages, a package
+
+8
+00:00:21,350 --> 00:00:25,480
+gatech inside package edu. And I can start creating classes inside
+
+9
+00:00:25,480 --> 00:00:28,770
+my packages. So here, I can use the contextual menu, select
+
+10
+00:00:28,770 --> 00:00:32,055
+New&gt;Class, and I'll get another wizard that will allow me to
+
+11
+00:00:32,055 --> 00:00:35,160
+specify the name of the class. I'm not very creative here,
+
+12
+00:00:35,160 --> 00:00:38,250
+so I'm just going to call it Hello World. There's many other parameters
+
+13
+00:00:38,250 --> 00:00:41,710
+you can set, and in particular, you can define whether you
+
+14
+00:00:41,710 --> 00:00:45,450
+want a main method in your class. Where having a main
+
+15
+00:00:45,450 --> 00:00:48,460
+method means that your class can be the main class in
+
+16
+00:00:48,460 --> 00:00:50,850
+your project, can be the one that is run when you run
+
+17
+00:00:50,850 --> 00:00:54,340
+your project. After we click the button, the Finish button, we,
+
+18
+00:00:54,340 --> 00:00:56,859
+we get the class. So we also get template code for the
+
+19
+00:00:56,859 --> 00:00:59,604
+class, as you can see here, so we go to the editor
+
+20
+00:00:59,604 --> 00:01:02,120
+function, you can see that there is a to do. Where you
+
+21
+00:01:02,120 --> 00:01:05,019
+have to put your code, and here we are simply, basically printing,
+
+22
+00:01:05,019 --> 00:01:08,370
+you know, the typical first program. We just going to print Hello World
+
+23
+00:01:08,370 --> 00:01:11,180
+in Java. And something you can note is that as we are
+
+24
+00:01:11,180 --> 00:01:16,370
+typing, Eclipse gives us a auto complete suggestions, which is very helpful.
+
+25
+00:01:16,370 --> 00:01:19,650
+For example, in case you don't remember the exact syntax,
+
+26
+00:01:19,650 --> 00:01:22,190
+or the method, or you don't remember the parameters of the
+
+27
+00:01:22,190 --> 00:01:24,470
+method. Which is, you know, often the case especially where you
+
+28
+00:01:24,470 --> 00:01:27,590
+work with large libraries. So having that feature can really, really
+
+29
+00:01:27,590 --> 00:01:30,050
+help you. So now if we want to run our code
+
+30
+00:01:30,050 --> 00:01:33,380
+we can either click on the button up here, or we
+
+31
+00:01:33,380 --> 00:01:37,960
+can right-click in the Call window and select Run As Java
+
+32
+00:01:37,960 --> 00:01:41,370
+Application. And if we do that, Eclipse will run our tool,
+
+33
+00:01:41,370 --> 00:01:45,650
+and it will create, as you can see here, a console view that basically contains
+
+34
+00:01:45,650 --> 00:01:49,790
+the textual output of my program. And as expected, the output is Hello World.

+So now that we have run our program, let's see what
+
+2
+00:00:02,660 --> 00:00:05,660
+happens exactly when you run a program within Eclipse. And to
+
+3
+00:00:05,660 --> 00:00:08,410
+do that I'm going to use the menu over here which is
+
+4
+00:00:08,410 --> 00:00:12,500
+the Run menu and I'm going to select Run Configurations, and this
+
+5
+00:00:12,500 --> 00:00:15,190
+brings up a window where you can change or run configurations.
+
+6
+00:00:15,190 --> 00:00:17,200
+Well first of all, you can see that here on the
+
+7
+00:00:17,200 --> 00:00:22,260
+left under Java application. Eclipse automatically created a Hello World run
+
+8
+00:00:22,260 --> 00:00:25,300
+configuration for our program. And this is where you can configure
+
+9
+00:00:25,300 --> 00:00:28,370
+the different parameters for your execution. For example,
+
+10
+00:00:28,370 --> 00:00:30,520
+you can select the main class. So here
+
+11
+00:00:30,520 --> 00:00:34,745
+it's, obviously, edu.gatech.HelloWorld. You can define different program
+
+12
+00:00:34,745 --> 00:00:36,920
+arguments. We don't have any for now. You can
+
+13
+00:00:36,920 --> 00:00:39,480
+also pass arguments to the virtual machine. You
+
+14
+00:00:39,480 --> 00:00:41,960
+can define which Java runtime environment you want to
+
+15
+00:00:41,960 --> 00:00:47,720
+use, Classpath and other environmental options. So let's
+
+16
+00:00:47,720 --> 00:00:50,650
+now try to pass some arguments to our program.
+
+17
+00:00:50,650 --> 00:00:54,390
+So for example here, I am just going to write George as
+
+18
+00:00:54,390 --> 00:00:58,450
+a possible parameter. I say Apply so that modify the configuration and
+
+19
+00:00:58,450 --> 00:01:01,510
+if i run the program of course, the output is not changing
+
+20
+00:01:01,510 --> 00:01:04,440
+because my program does not use the argument. But, let's see if
+
+21
+00:01:04,440 --> 00:01:07,060
+we do use the argument, what happens. So I'm going to slightly
+
+22
+00:01:07,060 --> 00:01:10,030
+modify the final program so that now, instead of printing hello
+
+23
+00:01:10,030 --> 00:01:13,420
+world, it will print hello followed by the first argument that I
+
+24
+00:01:13,420 --> 00:01:15,700
+will pass to the program. And if I do that, and I
+
+25
+00:01:15,700 --> 00:01:19,420
+go and I run the program, what I get is exactly what I
+
+26
+00:01:19,420 --> 00:01:23,420
+was expecting, which is Hello George. So this is the way in which you
+
+27
+00:01:23,420 --> 00:01:26,120
+can pass arguments to your execution, which
+
+28
+00:01:26,120 --> 00:01:27,640
+is something that might come in handy
+
+29
+00:01:27,640 --> 00:01:30,390
+for some other projects. When you need to run some code with an argument.

+1
+00:00:00,160 --> 00:00:03,090
+Now let's look at how we can do debugging within
+
+2
+00:00:03,090 --> 00:00:06,240
+Eclipse. I created a new file called AddNumbers which I'm
+
+3
+00:00:06,240 --> 00:00:10,770
+showing here. It takes two numbers, parses them into integers,
+
+4
+00:00:10,770 --> 00:00:14,870
+adds them and prints the sum, supposedly, of the two numbers.
+
+5
+00:00:14,870 --> 00:00:17,450
+Now we look at the run configuration for this program,
+
+6
+00:00:17,450 --> 00:00:19,670
+and here you can see that we're passing two arguments,
+
+7
+00:00:19,670 --> 00:00:22,060
+two and five, to the program. So now let's run
+
+8
+00:00:22,060 --> 00:00:25,468
+our program and see what happens. And the result says that
+
+9
+00:00:25,468 --> 00:00:28,150
+2 plus 5 is equal to 10, which is not
+
+10
+00:00:28,150 --> 00:00:31,030
+exactly correct. So we need to debug our program. We
+
+11
+00:00:31,030 --> 00:00:33,310
+need to figure out what's wrong with the program, why
+
+12
+00:00:33,310 --> 00:00:37,140
+the wrong result was, produced. So we're going to add a break
+
+13
+00:00:37,140 --> 00:00:40,260
+point here by double-clicking here on the side of the
+
+14
+00:00:40,260 --> 00:00:42,940
+code. And the break point is basically a place where I'm
+
+15
+00:00:42,940 --> 00:00:46,240
+telling my debugger to stop during the execution because I
+
+16
+00:00:46,240 --> 00:00:50,750
+want to inspect the state of the program. So to start
+
+17
+00:00:50,750 --> 00:00:54,690
+debugging, we select Debug as Java Application from the Context
+
+18
+00:00:54,690 --> 00:00:58,170
+menu, similar to what we were doing for running the program.
+
+19
+00:00:58,170 --> 00:01:00,190
+And as you can see, this asks us whether we want
+
+20
+00:01:00,190 --> 00:01:03,720
+to pass to the debug perspective, which is a, a perspective
+
+21
+00:01:03,720 --> 00:01:07,110
+specifically designed for debugging. We say yes. And as you
+
+22
+00:01:07,110 --> 00:01:10,750
+see here, it shows us, it's like a different, set of
+
+23
+00:01:10,750 --> 00:01:13,310
+views, so we can see the code down here with an
+
+24
+00:01:13,310 --> 00:01:16,100
+indication of where the execution is. And of course the execution
+
+25
+00:01:16,100 --> 00:01:18,610
+stopped at the break point, which is exactly where
+
+26
+00:01:18,610 --> 00:01:21,850
+we told the debugger to stop. So let's look at
+
+27
+00:01:21,850 --> 00:01:24,400
+some of the other views in this perspective. The view
+
+28
+00:01:24,400 --> 00:01:27,370
+here on the right-hand side, for example, shows the variables
+
+29
+00:01:27,370 --> 00:01:30,720
+in scope and the break points that are currently active
+
+30
+00:01:30,720 --> 00:01:33,240
+for the debugging session. This is where the editor is
+
+31
+00:01:33,240 --> 00:01:36,710
+at. The outline of the program and the console at
+
+32
+00:01:36,710 --> 00:01:41,520
+the bottom. So now let's execute one line by clicking
+
+33
+00:01:41,520 --> 00:01:45,400
+on the Step Over button here at the top, and this will
+
+34
+00:01:45,400 --> 00:01:49,150
+execute the line that is currently highlighted and therefore it will move to
+
+35
+00:01:49,150 --> 00:01:51,500
+the next line. And as you can see, one nice feature is that
+
+36
+00:01:51,500 --> 00:01:54,760
+if I move the mouse over a variable, I can see the value
+
+37
+00:01:54,760 --> 00:01:57,710
+of the variable. And the same thing I can do if I look
+
+38
+00:01:57,710 --> 00:02:00,690
+at the variables windows here on the right. If I click it, it
+
+39
+00:02:00,690 --> 00:02:03,960
+will tell me what is the value of the variable, and in case
+
+40
+00:02:03,960 --> 00:02:07,410
+of more complex variables you can even expand it and get more details.
+
+41
+00:02:07,410 --> 00:02:10,870
+So now let's step over another line by clicking again this button,
+
+42
+00:02:10,870 --> 00:02:13,180
+and as you can see now we get to the line that
+
+43
+00:02:13,180 --> 00:02:16,410
+is actually performing the sum, supposedly, so now let's do the same
+
+44
+00:02:16,410 --> 00:02:19,100
+thing that we did before, and let's mouse over b, and we can
+
+45
+00:02:19,100 --> 00:02:22,150
+see that the value of b is five, as expected. So now
+
+46
+00:02:22,150 --> 00:02:27,080
+let's step over this line as well, and execute the actual sum. And
+
+47
+00:02:27,080 --> 00:02:29,730
+doing the mouseover thing, we can see that the value of sum
+
+48
+00:02:29,730 --> 00:02:33,000
+is ten, which is not right, of course. In fact, if we check
+
+49
+00:02:33,000 --> 00:02:35,590
+a gain we can see that value of A is two. The
+
+50
+00:02:35,590 --> 00:02:39,130
+value of B is five and therefore it's clear that there's something
+
+51
+00:02:39,130 --> 00:02:41,780
+wrong going on here, and at this point we can notice that
+
+52
+00:02:41,780 --> 00:02:44,030
+here we are doing multiplication instead
+
+53
+00:02:44,030 --> 00:02:46,010
+of addition. And therefore that's what the
+
+54
+00:02:46,010 --> 00:02:49,260
+error is. And this is clearly a very simple case. Right? A
+
+55
+00:02:49,260 --> 00:02:51,440
+case in which probably you just needed to look at the code and
+
+56
+00:02:51,440 --> 00:02:54,150
+you didn't need the debugger. But you probably got the idea right?
+
+57
+00:02:54,150 --> 00:02:58,055
+So this can be extremely useful when you're debugging, when you're studying more
+
+58
+00:02:58,055 --> 00:03:01,533
+complex programs. If you want to stop the debugger because you're
+
+59
+00:03:01,533 --> 00:03:04,557
+done with your debugging session as in this case, you can
+
+60
+00:03:04,557 --> 00:03:07,518
+either click here on the Terminate button or you can also
+
+61
+00:03:07,518 --> 00:03:11,109
+just simply tell the debugger to continue the execution, to resume
+
+62
+00:03:11,109 --> 00:03:15,140
+the execution until the program terminates naturally. So, in this case,
+
+63
+00:03:15,140 --> 00:03:17,520
+we're going to click here just to show what happens. And what
+
+64
+00:03:17,520 --> 00:03:20,230
+happens is that, you know, the execution will just continue until
+
+65
+00:03:20,230 --> 00:03:23,690
+the program exits. So now let's say that we want to fix
+
+66
+00:03:23,690 --> 00:03:27,740
+this problem that we just discovered. So we replace the multiplication
+
+67
+00:03:27,740 --> 00:03:30,600
+with an addition, we save the program, and we execute the
+
+68
+00:03:30,600 --> 00:03:33,860
+program again by clicking on this button. And at this point,
+
+69
+00:03:33,860 --> 00:03:37,320
+unsurprisingly, we get the right result as shown in the console.
