J2ME手机游戏设计：Thread类

    继承Thread类的子类，可以覆盖Thread类的run()方法，run()方法被看做线程的起点。当要运行Thread时，需要调用start()来执行线程。MIDP Thread API示例6-11中说明线程的应用方法是：
    class PrimeThread extends Thread{
        long minPrime;
            PrimeThread(long minPrime){
              This.minPrime=minPrime;
     }
     public void run (){
     …
     }
     }

    本段为线程的基本编写方法。但是此时这段内容不会真正执行，需要调用下列方法才会执行。
    PrimeThread p = new PrimeThead(143);
    p.start();

    示例6-11

    import javax.microedition.lcdui.×;
    public class threadDemo1 extends MIDlet
    {
       Display display;
    　 //声明图片显示对象
       canvasThread canvasthread;
       public threadDemo1()
       {
          canvasthread=new canvasThread();
          display=Display.getDisplay(this);
       }
       public void startApp()
       {
          display.setCurrent(canvasthread);
       }
       public void pauseApp(){}
       public void destroyApp(boolean unconditional){}
       class canvasThread extends Canvas
       {
          int  gameaction=0;
          int  view=0;
          //声明一个线程
          goCanvas gocanvas;
          boolean  again;
          Image[ ]  cloudImage;
          Image[ ]  sunImage;
          public canvasThread()
          {
            try{
    　　　　　　//建立全部云朵图片数组
