Java开发中可以防止界面假死的刷新代码

try {  // 创建一个线程  Thread thread = new Thread() {  public void run() {   int i = 0;   while(true){   final long start = System.currentTimeMillis();   try {    Thread.sleep(1);   } catch (InterruptedException e) {    // TODO Auto-generated catch block    e.printStackTrace();   }   final int a = i;   if (!Display.getDefault().isDisposed()) {    Runnable runnable = new Runnable() {    public void run() {     processModel.setProcessName(start + "---" + a);    }    };    Display.getDefault().syncExec(runnable);   }   i++;   }  }  };  thread.start(); } catch (Exception e) {  e.printStackTrace(); }
