Java OCA OCP Practice Question 1060

Question

What is the output of the following snippet, assuming a and b are both 0? 

3:     try { 
4:       return a / b; 
5:     } catch (RuntimeException e) { 
6:       return -1; 
7:     } catch (ArithmeticException e) { 
8:       return 0; 
9:     } finally { 
10:      System.out.print("done"); 
11:    }
  • A. -1
  • B. 0
  • C. done-1
  • D. done0
  • E. The code does not compile.
  • F. An uncaught exception is thrown. 


E.

Note

The order of catch blocks is important because they're checked in the order they appear after the try block.

Because ArithmeticException is a child class of RuntimeException, the catch block on line 7 is unreachable.

If an ArithmeticException is thrown in try try block, it will be caught on line 5.

Line 7 generates a compiler error because it is unreachable code.
