non-static variable this cannot be referenced from a static context

Question

The error comes from this line BoardState addme = new BoardState();

For some reason the non-static variable that it is pointing at is \"new\". I am unclear of h

Answer 1

The reason it doesn't work is because your class BoardState is an inner, non-static, class inside of IntelligentTicTacToe. This means that when referring to it, you'll be referring to an instance of the class; the instance isn't available from a static context.

One solution is to declare that class as:

public static class BoardState {
