Java如何处理多线程的异常呢？

下文讲述Java中多线程处理异常的方法分享，如下所示：

class thisThread extends Thread{
   public void run(){
      System.out.println("即将抛出异常！");
      throw new RuntimeException();
   }
}
class testClass {
   public static void main(String[] args){
      thisThread  t = new thisThread();
      t.start();
      try{
         Thread.sleep(800);
      }
      catch (Exception x){
         System.out.println("异常:" + x);
      }
      System.out.println("程序运行结束！");
   }
}
