    Default Paint in Thread or Runnable

    import java.awt.Graphics;
     
    import javax.swing.JFrame;
     
    class node{
    	node(int a,node next){
    		this.a=a;this.next=next;
    	}
    	int a;
    	node next;
    }
    public class df extends JFrame implements Runnable{
    	Thread t;
    	node p,q;
    	node First;
    	public df(){
    		t=new Thread(this);
    		p=new node(1,null);
    		First=p;
    		q=p;
    		p=new node(2,null);
    		q.next=p;
    		q=p;
    		p=new node(3,null);
    		q.next=p;
    		q=p;
    		p=new node(4,null);
    		q.next=p;
    		q=p;
    		p=new node(5,null);
    		q.next=p;
    		q=p;
    		t.start();
    	}
    	public void run() {
    		p = First;
    		while (p != null) {
    			try {
    				repaint();
    				t.sleep(1000);
    			} catch (Exception e) {
    			}
    			p=p.next;
    		}
    	}
     
    	public void paint(Graphics g){
    		System.out.println(p.a);
     
    	}
     
    	public static void main(String[]as)	{
    		new df();
    	}
     
     
     
    }



    The code was ran not right, I want it's result is: 1 2 3 4 5 and delay(1000) every time that it prints a number
    exemple: 1 (delay(1000)) 2 (delay(1000)) ....
    and the paint must do that

    Use a Swing Timer. Oracle has a fine tutorial on using a Swing Timer.
