I'm trying to make a Tetris game and I'm getting the compiler error

Shape is not an enclosing class

when I try to create an object

public class Test {
    public static void main(String[] args) {
        Shape s = new Shapes.ZShape();
    }
}

I'm using inner classes for each shape. Here's part of my code

public class Shapes {
    class AShape {
    }
    class ZShape {
    }
}

What am I doing wrong ?

Answer

ZShape is not static so it requires an instance of the outer class.

The simplest solution is to make ZShape and any nested class static if you can.

I would also make any fields final or static final that you can as well.
