    int[ ][ ] X = new int[5][5];

    It can also be declared and initialized this way:

    int[][] X = {

    {1,2,3,6,8},

    {4, 5, 6, 9},

    {7,5,6,8,9},

    {8,5,8,8,9},

    {10,2,6,8,11},

    };

    Explanation:

    Above is a declaration of a two-dimensional array that can hold 5*5=25 int values. A java program is given below:

    public class JavaTwoD{

    public static void main (String args[ ]) {

    / / creating the 5X5 array

    int[ ][ ] X = new int[5][5];

    / / looping through the array to add elements

    for (int i = 0; i < X. length; i++) {

    for (int j = 0; j < X[i]. length; j++) {

    X[i][j] = i * j;

    }

    }
