Java swing 实现图片闪烁

Java swing实现一闪一闪的效果，其实思路只是建立一个线程，在线程中不断地切换你想要显示的图片以此达到闪烁的效果。以下附上主要的代码。

class TwinkledThread extends Thread{        public boolean twinkledFlag=false;        private long currentTimeMillis;        public TwinkledThread(long currentTimeMillis) {            this.currentTimeMillis=currentTimeMillis;        }        @Override        public void run() {            while(!twinkledFlag){                        try {                            markstationImg= markstation;                            Thread.sleep(100);                            // 闪动消息的提示图片                            markstationImg=null;                            Thread.sleep(100);    //此处控制闪烁的时长                                              if(System.currentTimeMillis()-currentTimeMillis>2000){                                twinkledFlag=true;                 }                        } catch (InterruptedException e) {                            // TODO Auto-generated catch block                            e.printStackTrace();                        }            }        }    }

class MyLabel extends JLabel{        /**         *          */        private static final long serialVersionUID = 1L;        @Override        public void paint(Graphics g) {        super.paint(g);        Graphics2D g2=(Graphics2D) g;            g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,RenderingHints.VALUE_ANTIALIAS_ON);            if(twinkledBs!=null){                if(markstationImg!=null){                    g2.drawImage(markstationImg.getImage(),                    twinkledBs.getX(),twinkledBs.getY(), this                    );                }            }          }          }
