Java Array Exercises: Add two matrices of the same size
Java Array: Exercise-19 with Solution
Write a Java program to add two matrices of the same size.
Pictorial Presentation:
Sample Solution:
Java Code :
import java.util.Scanner;
public class Exercise19 {
public static void main(String args[])
{
int m, n, c, d;
Scanner in = new Scanner(System.in);
System.out.println("Input number of rows of matrix");
m = in.nextInt();
System.out.println("Input number of columns of matrix");
n = in.nextInt();
int array1[][] = new int[m][n];
int array2[][] = new int[m][n];
int sum[][] = new int[m][n];
System.out.println("Input elements of first matrix");
for ( c = 0 ; c < m ; c++ )
for ( d = 0 ; d < n ; d++ )
array1[c][d] = in.nextInt();
System.out.println("Input the elements of second matrix");
for ( c = 0 ; c < m ; c++ )
for ( d = 0 ; d < n ; d++ )
array2[c][d] = in.nextInt();
for ( c = 0 ; c < m ; c++ )
for ( d = 0 ; d < n ; d++ )
sum[c][d] = array1[c][d] + array2[c][d];
System.out.println("Sum of the matrices:-");
for ( c = 0 ; c < m ; c++ )
{
for ( d = 0 ; d < n ; d++ )
System.out.print(sum[c][d]+"\t");
System.out.println();
}
}
}
Sample Output:
Input number of rows of matrix 2 Input number of columns of matrix 2 Input elements of first matrix 1 2 3 4 Input the elements of second matrix 5 6 7 8 Sum of the matrices:- 6 8 10 12

How to sort an ArrayList?
Collections.sort(testList); Collections.reverse(testList);
That will do what you want. Remember to import Collections though!
