Paint in Thread or Runnable

[EdgeThach]

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
please help me!

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