Java matrix addition
In this program, we are performing the addition of two matrices. Here we define two matrix one is first[][]
and another is second[][] and another one defines for summation of two entered matrices. First, we take row and column and then enter the values in two matrices. After then we sum the two matrices.
import java.util.Scanner;
