Modifying A 2D Array With A Method

Consider the following method.

public static void modifyMatrix(int[][] matrix) {
    for (int r = 0; r < matrix.length; r++) {
        for (int c = 0; c < matrix[r].length; c++) {
            if (r != c) {
                matrix[r][c] = -Math.abs(matrix[r][c]);
            } else {
                matrix[r][c] = Math.abs(matrix[r][c]);
            }
        }
    }
}

A 2D array, matrix, is initialized with the following values:

3 -3
-1 2
-4 4

What will be the contents of matrix after the call modifyMatrix(matrix) is executed?
