Java program to add two matrices

Java program to add two matrices


Output:

Enter the row size: 3
Enter the column size: 3
Enter the elements of matrix A:
1 2 3
4 5 6
7 8 9
Enter the elements of matrix B:
1 2 3
4 5 6
7 8 9
The resultant matrix is
2 4 6
8 10 12
14 16 18

Implementation:

import java.util.*; import java.lang.*; import java.io.*; class CodeRegister { public static void main (String[] args) throws java.lang.Exception { Scanner in = new Scanner(System.in); int r,c; System.out.println("Enter the row size:"); r=in.nextInt(); System.out.println("Enter the column size:"); c=in.nextInt(); int a[][]=new int[r][c]; System.out.println("Enter the elements of matrix A:"); for(int i=0;i<r;i++) { for(int j=0;j<c;j++) { a[i][j]=in.nextInt(); } } int b[][]=new int[r][c]; System.out.println("Enter the elements of matrix B:"); for(int i=0;i<r;i++) { for(int j=0;j<c;j++) { b[i][j]=in.nextInt(); } } int sum[][]=new int[r][c]; for(int i=0;i<r;i++) { for(int j=0;j<c;j++) { sum[i][j]=a[i][j]+b[i][j]; } } System.out.println("The resultant matrix is"); for(int i=0;i<r;i++) { for(int j=0;j<c;j++) { System.out.print(sum[i][j]+" "); } System.out.print("\n"); } } }
