### Java Program to perform Matrix Addition

In this post we will implement addition of two matrices with Java programming.

PROGRAM :
```package codingcorner.in;

import java.util.Scanner;

public static void main(String[] args) {
int i, j, rows1, rows2, columns1, columns2;

Scanner scan = new Scanner(System.in);

System.out.println("Enter order of matrix 1 :\t");

rows1 = scan.nextInt();
columns1 = scan.nextInt();

System.out.println("Enter order of matrix 2  :\t");
rows2 = scan.nextInt();
columns2 = scan.nextInt();

int[][] matrix1 = new int[rows1][columns1];
int[][] matrix2 = new int[rows2][columns2];
int[][] result = new int[rows1][columns1];

if (rows1 != rows2 || columns1 != columns2) {
System.out.println("Both matrices must have same  of order ");

} else {
System.out.println("Enter elements of matrix 1:");
for (i = 0; i < rows1; i++) {
for (j = 0; j < columns1; j++) {
System.out.print("Enter element m" + (i + 1) + (j + 1));

matrix1[i][j] = scan.nextInt();

}
}
System.out.println("Enter elements of matrix 2:");
for (i = 0; i < rows2; i++) {
for (j = 0; j < columns2; j++) {
System.out.print("Enter element m" + (i + 1) + (j + 1));
matrix2[i][j] = scan.nextInt();

}
}

scan.close();

System.out.println("MATRIX 1 is :");
for (i = 0; i < rows1; i++) {
for (j = 0; j < columns1; j++) {
System.out.print(matrix1[i][j]+"\t");
}
System.out.println("\n");
}
System.out.println("MATRIX 2 is :");
for (i = 0; i < rows2; i++) {
for (j = 0; j < columns2; j++) {
System.out.print( matrix2[i][j]+ "\t");
}
System.out.println("\n");
}
for (i = 0; i < rows1; i++) {
for (j = 0; j < columns1; j++) {
result[i][j] = matrix1[i][j] + matrix2[i][j];
}
}
System.out.println("The Addition of two Matrices is : ");
for (i = 0; i < rows1; i++) {
for (j = 0; j < columns1; j++) {
System.out.print("\t" + result[i][j]);
}
System.out.println("\n");
}
}
}
}```
OUTPUT :
