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<a.length; x++)  //loop for add rows

   {

       for(int y= 0; y<a[i].length; y++) //loop for add column

       {

           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.
