What is enums

Answer 1

Enums are lists of constants. When you need a predefined list of values which do not represent some kind of numeric or textual data, you should use an enum. You should always use enums when a variable (especially a method parameter) can only take one out of a small set of possible values.

Answer 2

They're actually a really useful way of making your code more readable. For example, if I was using hex codes for basic colors, I could just make enums for them. That way I could just say BLACK instead of #000000 or WHITE instead of #FFFFFF.

Answer 3
