Java OCA OCP Practice Question 660

Question

What is the output of the following application? 

package mypkg; //from  w  ww  .ja  v a  2s.  c o m

class Exception1 implements RuntimeException {} 

public class Main extends Exception1 { 
   public static void main(String uhOh[]) { 
      try { 
         throw new Main(); 
      } catch (Main re) { 
         System.out.print("Exception1?"); 
      } catch (Exception1 e) { 
         System.out.print("Handled"); 
      } finally { 
         System.out.print("Fixed!"); 
      } 
   } 
}
  • A. Exception1?Fixed!
  • B. Handled.Fixed!
  • C. Exception1?Handled.Fixed!
  • D. The code does not compile. 


D.

Note

The class RuntimeException is not an interface and it cannot be implemented.

The Exception1 class does not compile, and Option D is the correct answer.

This is the only compilation problem in the application.

If implements was changed to extends, the code would compile and Exception1?Fixed! would be printed, making Option A the correct answer.
