  catch(Exception ex) {
  System.out.println("Exception:"+ex.getMessage());
  }
  }
  }


------解决方案--------------------
调用fun2()，然后调用fun1()，在fun1()中会抛出一个异常
MyException，但是fun2()尤其定义可知，它并不会进行处理，
而是在其执行完之后将异常再抛出去（抛给调用者），所以
fun2()会执行到finally语句块，先输出"Go through finally ..."，
然后再回到main方法中调用fun2()后捕获异常的catch(MyException)，
所以也就会输出“MyException: An MyException ...”。
------解决方案--------------------
输出:

Go through finally code in fun2().
MyException:An MyException object is thrown in fun1().
