Question

Can somebody explain me what is the use of throws Exception in java?
Its just used to indicate that the method will throw the exception specified? The calling method need to catch the exception specified?

So instead of throws we can use a try-catch block to catch the exception?

How it differs from throw?
Thanks

Answer 1

Java uses explicit exception handling – except of RuntimeExceptions, every exception thrown [by the method itself, or a method it invokes declares it throws it]- must be handle or declared in the method signature.

It allows safety, since when you invoke a method you know exactly which errors might occur, which you can then either handle locally with try/catch blocks, or declare as part of your method signature.
