I'm running into problems trying to assign a 2d array to a 3d array, so I thought i'd ask a question about 3d and 2d arrays.

Say I have a masterArray[][][] and wanted to put childArray1[][] and childArray2[][] into it. This is how I have done it and was wondering if that is the correct way of applying it:

private int[][][] masterArray;
private int[][] childArray1 = {
        {1, 1, 1, 1, 1, 1, 1, 1, 1, 1},
        {1, 1, 1, 0, 0, 1, 0, 1, 1, 1},
        {1, 1, 1, 1, 1, 1, 1, 1, 1, 1},
        {1, 0, 1, 1, 1, 1, 1, 1, 0, 1},
        {1, 0, 1, 1, 1, 1, 0, 1, 0, 1},
        {1, 0, 1, 1, 0, 1, 0, 1, 0, 1},
        {1, 0, 1, 1, 0, 1, 1, 1, 0, 1},
        {1, 0, 1, 1, 1, 1, 1, 1, 0, 1},
        {1, 0, 1, 1, 0, 1, 1, 1, 0, 1},
        {1, 0, 1, 1, 0, 1, 8, 1, 0, 1},
        {1, 0, 7, 1, 1, 1, 0, 1, 0, 1},
        {1, 0, 1, 1, 1, 1, 0, 1, 0, 1},
        {1, 0, 1, 1, 1, 1, 1, 1, 0, 1},
        {1, 0, 0, 0, 0, 0, 0, 9, 0, 1},
        {1, 1, 1, 1, 1, 1, 1, 1, 1, 1}
};
private int[][] childArray2 = {
        {1, 1, 1, 1, 1, 1, 1, 1, 1, 1},
        {1, 1, 1, 1, 1, 1, 1, 1, 1, 1},
        {1, 1, 1, 1, 1, 1, 1, 1, 1, 1},
        {1, 1, 1, 1, 1, 1, 1, 1, 1, 1},
        {1, 1, 1, 1, 1, 1, 1, 1, 1, 1},
        {1, 1, 1, 1, 1, 1, 1, 1, 1, 1},
        {0, 0, 0, 0, 0, 0, 0, 0, 1, 1},
        {1, 1, 1, 1, 7, 1, 1, 1, 1, 1},
        {1, 1, 1, 1, 1, 1, 1, 1, 1, 1},
        {1, 1, 1, 1, 0, 1, 1, 1, 1, 1},
        {1, 1, 1, 1, 0, 0, 0, 1, 1, 1},
        {1, 1, 1, 9, 1, 1, 8, 0, 1, 1},
        {1, 1, 1, 1, 1, 1, 1, 1, 1, 1},
        {1, 1, 1, 1, 1, 1, 1, 1, 1, 1},
        {1, 1, 1, 1, 1, 1, 1, 1, 1, 1},
};

Ok, so in my init method I use these some methods to set the child arrays into the master array. What I was curious about was how this exactly works. I assumed the following:

    masterLevel = new int[MAX_LEVELS][MAP_WIDTH][MAP_HEIGHT];
    for (int x = 0; x < MAP_WIDTH; x++) {
        for (int y = 0; y < MAP_HEIGHT; y++) {
            masterArray[currentLevel][x][y] = childArray1[x][y];
        }
    }

Would that work? In my application things aren't working so I picking out code that I am not 100% sure on.
