printing out a 2-D array in Matrix format

Question

How can I print out a simple int [][] in the matrix box format like the format in which we handwrite matrices in. A simple run of loops doesn\'t apparently work. If it helps

Answer 1

final int[][] matrix = {
  { 1, 2, 3 },
  { 4, 5, 6 },
  { 7, 8, 9 }
};

for (int i = 0; i < matrix.length; i++) {
    for (int j = 0; j < matrix[i].length; j++) {
        System.out.print(matrix[i][j] + " ");
    }
    System.out.println();
}

Produces:

1 2 3
4 5 6
7 8 9
