java编程思想第3版 第九章习题6
编译通不过....谁能告诉我是什么问题......谢谢
class myException1 extends Exception
{}
class myException2 extends Exception
{}
class T
{
  void g() throws myException1
  {
     throw new myException1();
  }
  public void f()
  {
     try{g();}
     catch(myException1 e){throw new RuntimeException(e);}
  }
}
public class Test
{
   public static void main(String[] arg)
   {
      T t=new T();
      try{
          t.f();
          if(false){throw new myException2();}
      }
      catch(RuntimeException re)
      {
          try{throw re.getCause();}
           catch(myException1 e){System.out.println(e);}
      }
      catch(myException2 e){}
    }
}

问题解决了,但是为什么在第九章最后的那个例子中并不象现在这样声明呢?

哦,谢谢了
