Java Program to add two matrices

Last Updated : 17 Mar 2025

We can add two matrices in java using binary + operator. A matrix is also known as array of arrays. We can add, subtract and multiply matrices.

To subtract two matrices, use - operator. Let's see a simple example to add two matrices of 3 rows and 3 columns.

public class MatrixAdditionExample{
public static void main(String args[]){
//creating two matrices  
int a[][]={{1,3,4},{2,4,3},{3,4,5}};  
int b[][]={{1,3,4},{2,4,3},{1,2,4}};  
  
//creating another matrix to store the sum of two matrices  
int c[][]=new int[3][3];  //3 rows and 3 columns
  
//adding and printing addition of 2 matrices  
for(int i=0;i<3;i++){  
for(int j=0;j<3;j++){  
c[i][j]=a[i][j]+b[i][j];    //use - for subtraction
System.out.print(c[i][j]+" ");  
}  
System.out.println();//new line  
}  
}}

Test it Now

Output:

2 6 8
4 8 6
4 6 9
