[Java] 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();
 }
