    What methods throw an exception?
    What do you want to do if one of them throws an exception?
    For example if a method throws an exception you might want to provide a default value
    or end the program.

    I put try; right before the if statements and I get an error saying I need to put finally after the last closing bracket. I'm familiar with catch(Exceptions e) but not finally can someone explain why you need finally?

    When you get errors, please copy the full text and paste it along with the source that caused it.

    See the tutorial: The Catch or Specify Requirement (The Java™ Tutorials > Essential Classes > Exceptions)
