Valid Java programming language code must honor the Catch or Specify Requirement. This means that code that might throw certain exceptions must be enclosed by either of the following:
*A try statement that catches the exception. The try must provide a handler for the exception, as described in Catching and Handling Exceptions.
*A method that specifies that it can throw the exception. The method must provide a
throws clause that lists the exception, as described in Specifying the Exceptions Thrown by a Method.
Code that fails to honor the Catch or Specify Requirement will not compile.
