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

public static void printMatrix(double[][] matrix) {
    for (double[] row : matrix) {
        for (double element : row) {
            System.out.printf("%5.1f", element);
        }
        System.out.println();
    }
}

Function Call

printMatrix(new double[][]{2,0,0},{0,2,0},{0,0,3}});

Output:

  2.0  0.0  0.0
  0.0  2.0  0.0
  0.0  0.0  3.0
