Answer 1

You might want to go through some Java basics:

http://docs.oracle.com/javase/tutorial/java/javaOO/index.html

You are attempting to use a property of Player in a static method. A static method is not part of an instance so it doesn't know what "cash" (as it's unique to every Player instance rather than a single variable).

Remove the "static" from wagerBet so that it becomes a method of Player. That way it's unique to every Player and so it'll know to use the "cash" of the same Player it's a part of.

Answer 2

remove static at

public static double wagerBet()

Answer 3

There is only one real problem. To understand what static is.

Basic approach, until you are good enough, is to NOT use static at all. Remove it in all cases instead of "main" (you have to keep it there).

Answer 4

The cash variable doesn't belong to any method. It is an instance member of the class. You can't access it from a static method. Make the method non-static, or pass 'cash' to it as a parameter if you only need to read its value there.
