Download this file in which we have started the add) method. You need to complete this method so that it allocates a new array with the same number of rows as the parameters have. Set each row to a new array with the same number of entries as the number of columns in the parameters. Set the value of each entry in your solution equal to the sum of the entries at the identical row and column in the parameters. Once this has been completed, return the new array. You can see the tests and check your solution using the MatrixAdditionTest class in this JAR file
