The throws statement is how you create an exception stack trace.

The throws statement is how you create an exception stack trace. There isn't much magic in java--it's not some underlying system mystery that creates an exception, it is simply a "Throw" statement, and therefore the last few entries in any stack trace will probably be throw. It's not JUST the last one because in many cases exception handling consists of something like this: try { do something that might cause an exception catch(ExpectedException e) { throw new DifferetnException(e); } This lets you change what type of exception it was or add a better textual description or even handle some of the exceptions while re-throwing the others. Because of this it is often the last few levels (and maybe some in-between) that are caused by the "Throw" statement. read less

If a function is not handling the exception throws clause can be added to the function signature. This includes the list of exceptions which can be thrown by the function

The throw keyword is used to throw an exception from within a method. When a throw statement is encountered and executed, execution of the current method is stopped and returned to the caller. Whereas the throws keyword is used to declare that a method may throw one or some exceptions.
