Exception see the slides. We didn't mention "finally" clause. Here 
is the description taken from http://java.sun.com:
  The finally block *always* executes when the try block exits. 
  This ensures that the finally block is executed even if an 
  unexpected exception occurs. But finally is useful for more 
  than just exception handling — it allows the programmer to 
  avoid having cleanup code accidentally bypassed by a return, 
  continue, or break. Putting cleanup code in a finally block is 
  always a good practice, even when no exceptions are anticipated.
