Enumeration - a collection of items that is a complete, ordered listing of all of the items in that collection.

[Wikipedia - Enumeration]

Sounds simple isn't it? Even if, Enums in Java allows us for many things and it's a really great language's feature, which can increase quality of our code.

What happens in try-catch-finally?

let's talk about basics

Try-catch is the most popular way to handle exceptions and with finally block you can really make your code cleaner and make life of all developers who will use it - easier.
As usual I will cover whole code with tests to proof that it works as expected (this time without TDD, because it wouldn't give us any advantages).
