Write a program to input and store integer elements in a double-dimensional array of size 4 × 4 and find the sum of all the elements.


import java.util.*;
class Sum{
    public static void main(String args[]) {
        Scanner in = new Scanner (System.in);
        int a[][] = new int[4][4];
        int sum = 0;
        System.out.println("Enter 16 integers:");

        for(int i = 0; i < 4; i++){
            for(int j = 0; j < 4; j++){
                a[i][j] = in.nextInt();
                sum += a[i][j];
            }
        }
        System.out.println("Sum = " + sum);
    }
}
