====Multi-dimensional arrays====
In Java, multi-dimensional arrays are represented as arrays of arrays. Technically, they are represented by arrays of references to other arrays.

<syntaxhighlight lang="java">
int[][] numbers = new int[3][3];
numbers[1][2] = 2;

int[][] numbers2 = {{2, 3, 2}, {1, 2, 6}, {2, 4, 5}};
</syntaxhighlight>

Due to the nature of the multi-dimensional arrays, sub-arrays can vary in length, so multi-dimensional arrays are not bound to be rectangular unlike C:
<syntaxhighlight lang=Java>
int[][] numbers = new int[2][]; //Initialization of the first dimension only

numbers[0] = new int[3];
numbers[1] = new int[2];
</syntaxhighlight>
