+1 A:

Hi, I can't guess what you are searching for a way to run program from terminal? Use Runtime.getRuntime().exec(program_call_command); Example will print folder content on GNU/Linux:

  public class Executor {
        public static void main(String[] args) throws IOException {
            Process p = Runtime.getRuntime().exec("ls");
            InputStream in = p.getInputStream();
            int size = in.available();
            byte[] buf = new byte[size];
            in.read(buf);
            System.out.println(new String(buf));
        }
    }

Or maybe if all your programs are in java, you can create a new thread for each and call main method for every program.

public class Executor {
    public static void main(String[] args) throws IOException {
        System.out.println("Executor started");
        Thread thread = new Thread(){
            @Override
            public void run() {
                Prog_1.main(null);
            }
        };
        thread.start();

        System.out.println("Executor finished");
    }

}

class Prog_1{
    public static void main(String[] args) {
        System.out.println("I am going to sleep");
        try {
            Thread.sleep(2000);
        } catch (InterruptedException e) {
            System.out.println("Really, don't whant to");
        }
        System.out.println("Its time to wake up");
    }
}

Answer 3

A:

You see, you guys didn't quite understand what I'm asking, nad I'm sorry if I mislead you there.

Here's the thing: I have sub-classes in Java, classes under the Main class. They won't run alone, only if the Main class executes them. I've been able to do that in CMD in Windows. Now, I want to do the same thing, but run all of them in a GUI. I cannot make the Main class execute the sub-class inside itself (to show it on a frame of the Main class). I want to make it so the Main class can be used to choose one of the ten programs I have, execute them in a GUI inside the Main (a frame) and then, when the chosen program is finished, return to the Main class again.

I'm sorry for this Answer Post. However, I'm not able to Edit the Original Question for some reason...

I hope now you can understand what I was asking. Thanks for you time answering the question.
