Exam 1z0-809 topic 1 question 14 discussion

C is the correct answer. public class Test { static void doStuff() throws ArithmeticException, NumberFormatException, Exception { if (Math.random() > -1) throw new Exception("Try again"); } public static void main(String[] args) { try { doStuff(); } catch (ArithmeticException | NumberFormatException e) { System.out.println(e.getMessage()); } catch (Exception e){ System.out.println(e.getMessage()); } } }

C is correct since Exception classes in multi-catch must be unrelated. Also if superclass and sublass are caught then code must first catch subclass and then superclass.

Option C is correct despite the fact that the code wouldnt still compile because of error on line 5 (missing closing bracket in the if)

Option A can't compile Types in multi-catch must be disjoint: 'java.lang.NumberFormatException' is a subclass of 'java.lang.Exception'

Answer C is better than A. Code is more readable.

Ans: C. If you do A, you still get this exception The exception ArithmeticException is already caught by the alternative Exception
