Given:

11. static void test() throws Error{

12.   if(true) throw new AssertionError();

13.   System.out.print("test ");

14. }

15. public static void main(String[] args){

16.   try{test();}

17.   catch(Exception ex){System.out.print("exception ");}

18.   System.out.print("end ");

19. }

What is the result?

A. end

B. Compilation fails.

C. exception end

D. exception test end

E. A Throwable is thrown by main.

F. An Exception is thrown by main.

 

Ans: E

 

解說:

Test方法丟出一個AssertionError物件，但此錯誤物件型態不會被17行補捉到，因此main會丟出AssertionError(Throwable的子類別)而不正常結束
