Question: Develop a Java program (name it SumArrayColumns) that prints out the sum of each column of a two-dimensional array. The program defines method sumColumn ()

Develop a Java program (name it SumArrayColumns) that prints out the sum of each column of a two-dimensional array. The program defines method sumColumn() takes a two-dimensional array of integers and returns a single-dimensional array that stores the sum of columns of the passed array. The program main method prompts the user to enter a 3-by-4 array, prints out the array, and then calls method sumColumns(). Final, it prints out the array retuned by method sumColumns(). Document your code, and organize and space the outputs properly as shown below.

Sample run 1:

The entered matrix:

9 1 2 4

2 2 8 0

3 3 3 3

Sum of column 0 is 14

Sum of column 1 is 6

Sum of column 2 is 13

Sum of column 3 is 7

Sample run 2:

The entered matrix:

10 10 10 10

1 1 1 1

50 50 50 50

Sum of column 0 is 61

Sum of column 1 is 61

Sum of column 2 is 61

Sum of column 3 is 61

Sample run 3:

The entered matrix:

10 10 10 10

-10 -10 -10 -10

50 51 52 53

Sum of column 0 is 50

Sum of column 1 is 51

Sum of column 2 is 52

Sum of column 3 is 53
