Java applet不会显示图像

Question

I was trying to program my first Java applet and shortly after I started, I already have 2 problems.

1. The images won't show
2. Whenever I use the while-loop, which is converted into a comment in the following code, the applet won't do anything after initialising and won't react, too.

I already searched for the problem, but I can't find anything.

import java.awt.Graphics;
import java.awt.Image;
import java.awt.image.CropImageFilter;
import java.awt.image.FilteredImageSource;

import javax.swing.ImageIcon;
import javax.swing.JApplet;


public class start extends JApplet implements Runnable{


    public boolean pause = false;

    public Image bg;
    public Image back;
    public Image ground;
    public Image front;

    public void init(){

        setSize(800, 450);
        bg = getImage(getCodeBase(),"res/bg.PNG");      
        back = getImage(getCodeBase(),"res/back.PNG");
        ground = getImage(getCodeBase(),"res/ground.PNG");
        front = getImage(getCodeBase(),"res/front.PNG");
    }

    public void start(){
        Thread game = new Thread();
        game.start();
        run();
    }

    public void stop(){
    }

    public void destroy(){

    }

    public void run(){
        Thread.currentThread().setPriority(Thread.MIN_PRIORITY);

//      while(!pause){
//          repaint();
//          
//          try{
//              Thread.sleep(25);
//          }catch(InterruptedException e){
//              
//          }

//      }

        Thread.currentThread().setPriority(Thread.MAX_PRIORITY);
    }



    public void paint(Graphics g){
        g.drawImage(bg, 10, 10, this);
        g.drawImage(back, 10, 10, this);
        g.drawImage(ground, 10, 10, this);
        g.drawImage(front, 10, 10, this);
    }

}

I think that you're trying to do what the example in here: Java: In what order are the methods called in an Applet? does, if you note, the constructor of Thread used have reference to this and by the way, you don't need to call run yourself as this is part of the Thread class.
