Write a class called TwoDArray that has the following behaviors for an array of ints. getTotal – Accepts a 2-D array as its argument and returns the total of all the values in the array getAverage – Accepts a 2-D array as its argument and returns the average of all the values in the array getRowTotal - Accepts a 2-D array as it 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 - Accepts a 2-D array as it first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The method should return the total of the values in the specified column. getHighestInRow - Accepts a 2-D array as it 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 highest value stored in the specified row of the argument array. getLowestInRow - Accepts a 2-D array as it 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 lowest value stored in the specified row of the argument array. getElementCount - Accepts a 2-D array as its argument and returns the count of how many values are in the array.

3. 2D Array

Write a class called TwoDArray that has the following behaviors for an array of ints.

getTotal – Accepts a 2-D array as its argument and returns the total of all the values in the array
getAverage – Accepts a 2-D array as its argument and returns the average of all the values in the array
getRowTotal - Accepts a 2-D array as it 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 - Accepts a 2-D array as it first argument and an integer as its second argument. The second argument should be the subscript of a column in the array. The method should return the total of the values in the specified column.
getHighestInRow - Accepts a 2-D array as it 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 highest value stored in the specified row of the argument array.
getLowestInRow - Accepts a 2-D array as it 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 lowest value stored in the specified row of the argument array.
getElementCount - Accepts a 2-D array as its argument and returns the count of how many values are in the array.

Test Run

Processing the int array.

There are 6 elements in the array

Total value of elements in the array: 26

Average : 4.333333333333333

Total of row 0 : 12

Total of row 1 : 14

Total of col 0 : 9

Total of col 2 : 13

Highest in row 0 : 9

Highest in row 1 : 7

Lowest in row 0 : 1

Lowest in row 1 : 3
