Using arrays in enums Java

Question

A part of my Java assignment requires me to create an enumeration which represents four different types of masks (shapes) which cover squares of a game board. The masks are 3x3 in measurement, with some squares of the 3x3 block missing (these do not hide squares on the game board).

1 0 1  //you can think of the 0's as missing squares, and the 1's as the mask
1 1 1
1 1 0

Now I want to attach a binary matrix to like above to each of the four unique masks using arrays like int[][], like so:

public enum Mask {
    W([[1,1,0],[1,1,1],[1,0,1]]),
    X([[1,0,1],[1,0,1],[1,1,1]]),
    Y([[0,1,1],[1,1,1],[1,1,0]]),
    Z([[1,0,1],[1,1,1],[1,0,1]]);

My IDE becomes very unhappy when I try to do this, so I'm sure I'm missing something in my understanding of enums/arrays.

I'm guessing I can't initialize the array in the enum or something like that?

How do I implement this idea?
