I wanted to output a text for a certain amount of time. One way is to use threads. Are there any other ways? I can't use threads for slick2d. This is my code when I use threads for slick:

package javagame;
import org.newdawn.slick.GameContainer;
import org.newdawn.slick.Graphics;
import org.newdawn.slick.Image;
import java.util.Random;
import org.newdawn.slick.Input;
import org.newdawn.slick.*;
import org.newdawn.slick.state.*;
import org.lwjgl.input.Mouse;

public class thread1 implements Runnable {
    String showUp;
    int timeLeft;

    public thread1(String s)
    {
        s = showUp; 
    }

    public void run(Graphics g)
    {
        try {
           g.drawString("%s is sleeping %d", 500, 500);
           Thread.sleep(timeLeft);
           g.drawString("%s is awake", 600,600);

        } catch(Exception e) { }
    }

    @Override
    public void run() {
        // TODO Auto-generated method stub
        run();
    }
}

It auto generates a new run() And also when I call it to my main class it has stack overflow!
