2 Dimension Array of Objects

You can not only do a two dimensional array of primitive types, but you can also do two dimensional arrays of objects/classes.

animalLocation[][] map;
map = new animalLocation[5][4];

Since we are dealing with classes, you cannot use this array right away. The code above creates the space in memory to store the objects. To have the animalLocation objects in the array, you must new each instance of the object.

for (int i = 0; i < map.length; i++) {
    for (int j = 0; j < map[i].length; j++) {
        map[i][j] = new animalLocation();
    }
}
