操作画面：

按空格开始，按空格向上跳动

可以在control方法里设置birdY后的数字来改变每次空格鸟跳动的高度

 public void control() {

        System.out.println("hello");
        //加键盘的监视器,后面就是键盘监视器的类
        addKeyListener(new KeyAdapter() {

            public void keyPressed(KeyEvent e) {
                System.out.println(e.getKeyCode());
              if(e.getKeyCode()==32) {
                  birdY -= 70;
                  welcom1=false;
                  start=true;
              }else if(e.getKeyCode()==82)
              {
                  start=false;
                  welcom1=true;
                  show=false;
                  FlappyBird c=new FlappyBird();
                  mainWindows();
              }
            }
        });
    }

可以更改bird方法下的birdY+=之后的数字来更改鸟的下落速度

同理可更改pipe方法下的
