Exceptions and exceptions....

I understand exceptions and their functionalities but still don't quite get why we should use them and keywords associated with them, as throws and the try-with-resources and catch block.

We need to use exceptions in a situation where the user enters the information which we do not need. For ex: We want the user to enter just alphabets but if they enter numbers which we don't need, should prompt them "Enter alphabets only" using try and catch blocks. So we are just putting the code which might cause exception in try block, when the try block throws an exception that will be handled in catch block.
