如何使用線程異常？

解決方法

這個例子顯示了如何處理異常及處理線程。

class MyThread extends Thread{
   public void run(){
      System.out.println("Throwing in " +"MyThread");
      throw new RuntimeException();
   }
}
class Main {
   public static void main(String[] args){
      MyThread t = new MyThread();
      t.start();
      try{
         Thread.sleep(1000);
      }
      catch (Exception x){
         System.out.println("Caught it" + x);
      }
      System.out.println("Exiting main");
   }
}

結果

上麵的代碼示例將產生以下結果。

Throwing in MyThread
Exception in thread "Thread-0" java.lang.RuntimeException
        at testapp.MyThread.run(Main.java:19)
Exiting main
