-00:00:00,140 --> 00:00:02,660

-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.
