    Default Need help populating two matrices with method

    This is the method public void populateMatrices(int [][]mat1, int [][]mat2). I know how to do it for one matrix, but what do we do for the additional matrix? Here is the code I have so far.
    for (int row =0; row<mat1.length;row++){
    for (int column = 0; column<mat1[row].length;column++){
    mat1[row][column]=1 + (int)(Math.random()*5);
    Any help would be appreciated.
    Thanks

    Welcome to the forum! Please read this topic to learn how to post code in code or highlight tags and other useful info for new members.

    Please post your code correctly per the above link.

    For the second matrix, simply add the line:

    mat2[row][column]=1 + (int)(Math.random()*5);

    to the nested for() loop body, modifying as needed the formula for the mat2 values.
