Answer

java.lang.Object

public class Answer extends Object

Purpose:Stores the answer to a simple yes/no question.

Superior to Boolean in that you can pass it to a method as a parameter, that method sets the value to either true or false, and then see the answer after.

I.e. if a method finds the answer to a question while doing some calculations, it can mark the answer so another method doesn't need to do those calculations again just to see what the answer is.

I.e. in a method that gets something, might want some clue after as to from where that something was gotten from.
