public class MoveThread extends Thread {
        @Override
        public void run() {
            while ((true)) {
                try {
                    sleep(10);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                repaint();
            }
        }
    }
这段有点不是很懂
整句话就了解是个增加移动线程  和 调用 Thread这个类
下面TRY什么的  
不是很懂
求大神帮忙看看

catch (InterruptedException e) {
                    e.printStackTrace();
                }
是个什么意思额
搞了好久没搞懂
