Question

(Java in Eclipse)

 Write code that finds the sum of two matrices. Use the following method header 
public static int[][] addMatrix(int[][] a, int[][] b)


The rules for adding two matrices are:
1. both matrices should have the exact same dimensions (i.e. height and width) – you need to check for this rule in your program.
2. both matrices should have elements that have compatible types – you don’t have to add extra code to check this rule in your method as it will only accept int arrays

included is a test class and a sample run

Use the following class to test the methods you develop
public class Test {
public static void main (String[] args) {
{ 14, 11, 13, 12 },
{ 18, 15, 13, 13 },
{ 19, 16, 15, 17 } };
int [] [] ml
%3D
{ 54, 53, 51, 52 },
{ 51, 59, 52, 56 },
{ 53, 54, 52, 58 } };
int [] [] m2
System.out.println ("First array:");
displayArray (ml);
System.out.println ("Second array:");
displayArray (m2);
/* write simple code to test your method and use
displayArray to display the result if applicable
//write your methods code here.
public static void displayArray (int [) m) {
for (int r = 0; r < m.length; r++) {
for (int c = 0; c < m[r].length; c++)
System.out.print (m[r] [c] + " ");
System.out.println ();
For all questions, assume that we use only rectangular arrays (i.e., all rows have the same length).

As seen in the image below, the resulting matrix elements should be the sum of the respective pair
of elements from the two matrices (that are being added):
b1 b12 b13
aj1 + bi a12 + b12 a13 + b13
az1 + b21 a2 + b2 az3 + b3
a12
a13
b21 b2
b3

a33/
b31
b32
b33)
a31 + b31
a32 + b32 a33 + b33
Test your program using the Test class
Sample run
First array:
14 11 13 12
18 15 13 13
19 16 15 17
Second array:
54 53 51 52
51 59 52 56
53 54 52 58
The addition of the above two arrays is
68 64 64 64
69 74 65 69
