/** * Java allows two-dimensional arrays, that is, an array of arrays. * In mathematics, a two-dimensional array, each with the same dimension, is called a matrix. * * This assignment will have you do a number of specific operations on a matrix. * The number of rows is given by the ROWS constant. Similarly, the number * of columns is given by the COLS constant. Do NOT hard code 8 for these values! * * Wherever you see the comment: * // your code goes here * you have some coding to do to complete the method. * The documentation for the method appears above its declaration. * *
