用Java开发C/S应用（三）：计时器稍加改动，改为一个动态时钟

这里直接贴代码了，在上一篇文章的基础上，就不做解释了：

        Runnable runnable = new Runnable() {
            public void run() {
                while (true) {
                    Display.getDefault().asyncExec(new Runnable() {
                        public void run() {
                            
                            java.text.DateFormat df = new java.text.SimpleDateFormat( "yyyy-MM-dd HH:mm:ss"); 
                            String s = df.format(new java.util.Date()); 
                            
                            text.setText(s);
                        }
                    });

                    try {
                        Thread.sleep(1000);
                    } catch (InterruptedException e) {
                    }
                }
            }
        };
        Thread clock = new Thread(runnable);
        clock.start();
