Java runnable problems

Question

Currently this is my code

package com.raggaer.frame;

import java.awt.Dimension;
import java.awt.Graphics;

import javax.swing.JFrame;

public class Frame {

    private JFrame frame;

    public Frame() {

        this.frame = new JFrame("Java Snake");
        this.frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);      
        this.frame.add(new Panel());

        Paint game = new Paint();

        this.frame.setResizable(false);
        this.frame.pack();
        this.frame.setVisible(true);

    }
}

And this is my paint class

package com.raggaer.frame;

public class Paint implements Runnable {

    private Thread thread;

    public Paint() {

        thread = new Thread(this);
        thread.start();
    }

    public void run() {

        System.out.println("aaa");

    }

}

But the System.out.println("aaa"); is just executing one time instead of forever.. what Im doing wrong?

Answer 1

You'll have to loop in the run() method if you want it to run forever. Otherwise the thread finishes execution and exits.

Answer 2

Try This :

           public void run() 
           {
              while(true)
              System.out.println("aaa");
            }

Answer 3

When the run() method returns/ends the thread will be terminated. If you want the thread to continue 'forever' you can use while(true) or recall the run() method inside the run() method.
