Il programma di mio figlio Daniele

Daniele sta costruendo un programma in Java.
Ecco il codice:

package supercraftdemo;

import java.applet.*;

public class Component extends Applet implements runnable{
    private static final long serialVersionUID = 1L;
    private static int pixelSize = 2;
    public static Dimension size = new Dimension(700,560);
    public static Dimension pixel = new Dimension(size.width / pixelSize, size.height / pixelSize);
    
    public static String name = "supercraft";
    
    public static boolean isRunning = false;
    
    private image screen;
    
    public static Level level;
    
 public Component(){
     setPreferedSize(size);
     

 }

 public void start(){
  //definire oggetti
  level = new Level();
  
  //inizio loop del gioco
  isrunning = true;
  new trhead(this).start();
 }
 
 public void stop (){
  isRunning = false;
 }
 
 public static void main(String args []) {
               Component  component = new Component();
               
               JFrame = new JFrame();
}
