Java OCA OCP Practice Question 1102

Question

Which of the following can be inserted in the blank to make the code compile?

Choose all that apply 

public static void main(String[] args) { 
 try { 
   System.out.println("work real hard"); 
 } catch (                        e) { 
 } catch (RuntimeException e) { 
 } 
}
  • A. Exception
  • B. IOException
  • C. IllegalArgumentException
  • D. RuntimeException
  • E. StackOverflowError
  • F. None of the above. 


C, E.

Note

Option C is allowed because it is a more specific type than RuntimeException.

Option E is allowed because it isn't in the same inheritance tree as RuntimeException.

It's not a good idea to catch either of these.

Option B is not allowed because the method called inside the try block doesn't declare an IOException to be thrown.

The compiler realizes that IOException would be an unreachable catch block.

Option D is not allowed because the same exception can't be specified in two different catch blocks.

Finally, option A is not allowed because it's more general than RuntimeException and would make that block unreachable.
