Write a method named matrixAdd that accepts a pair of two-dimensional arrays of integers as parameters, treats the arrays as 2D matrices and adds them, returning the result. The sum of two matrices A and B is a matrix C where for every row i and column j, Cij = Aij + Bij. You may assume that the arrays passed as parameters have the same dimensions.

The code to this question can be given as follows:

Code:

int matrixAdd (int[][] a, int[][] b) / /defining method matrixAdd

{

int c[x][y]=0; //defining variable

for (int x = 0; x
{

for (int y = 0; y
{

int c[x][y] = a[x][y] + b[x][y]; / /add array elements

}

}

return c[x][y]; //return value

}

Explanation:

In the above method definition code, a method "matrixAdd" is defined that contains two integer 2D arrays "a[][] and b[][]" in its parameter, and this function returns the sum of both array.

Inside this method, another integer 2D array "c[][]" is defined that contains nothing. To add all array elements the for loop is defined, which uses the array variable "c[][]" to add all array elements and return its value.
