Java Program to add two matrices

We can add two matrices in java using add(+) operator.

There two matrices a and b of same size.
Create rows and columns from sc.nextInt() method.
Declare first matrix from two for loop,one for row and another for columns.storing data in matrix b.
Declare second matrix from two for loop,one for row and another for columns.storing data in matrix c.
Create a new Matrix to store the sum of the two matrices
Traverse each element of the two matrices and add them. Store this sum in the new matrix at the corresponding index.
Print the final new matrix

				
					import java.util.Scanner;

public class AddMatrix {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int x, y;
		int a[][] = new int[4][4];
		int b[][] = new int[4][4];
		int c[][] = new int[4][4];

		System.out.println("enter the number of rows :");
		x = sc.nextInt();
		
		System.out.println("enter the number of columns :");
		y = sc.nextInt();
		
		System.out.println("enter the first matrix :");
		for (int i = 0; i < x; i++) {
			for (int j = 0; j < y; j++) {
				b[i][j] = sc.nextInt();
			}
		}
		System.out.println("enter the second matrix :");
		for (int i = 0; i < x; i++) {
			for (int j = 0; j < y; j++) {
				c[i][j] = sc.nextInt();
			}
		}

		System.out.println("Sum of two matrices is :");
		for (int i = 0; i < y; i++) {
			for (int j = 0; j < y; j++) {
				a[i][j] = b[i][j] + c[i][j];
				System.out.print(a[i][j] + " ");
			}
			System.out.println();
		}

	}

}

Output :-

enter the number of rows :
2
enter the number of columns :
2
enter the first matrix :
1
2
3
4
enter the second matrix :
5
6
7
8
Sum of two matrices is :
6 8
10 12
