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>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. -- cgit 1.4.1
