Exceptions
... When a problem occurs, Java attempts to transfer control to a method that can deal with the problem. Such methods are called exception handlers. An exception handler can either correct the problem (fault handlers), gracefully terminate the program (trap handlers), or simply ignore the problem. Java ...
