The program should have the following methods: • getTotal. This method should accept a two-dimensional array as its argument and return the total of all the values in the array. • getAverage. This method should accept a two-dimensional array as its argument and return the average of all the values in the array. • getRowTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a row in the array. The method should return the total of the values in the specified row. • getColumnTotal. This method should accept a two-dimensional array as its first argument and an integer as its second argument. The second argument should be the subscript of a column in the array.
