Question

Write a java program to enter 10 elements in an array. Find the sum of all array elements which are divisible by 7. Also the elements along with the sum.

Answer 1

Answer:

import java.util.Scanner;

public class ArrSum {

private int[] arr;

public void input() {

Scanner sc = new Scanner(System.in);

arr = new int[10];

System.out.println("Enter 10 no.s");

for (int i = 0; i < 10;i++) {

arr[i] = sc.nextInt();

}

}

public void display() {

int sum = 0;

System.out.println("\nElements divisible by 7 are");

for (int i: arr) {

if (i % 7 == 0) {

System.out.println(i);

sum += i;

}

}

System.out.println("\nSum = "+ sum);

}

public static void main(String[] args) {

ArrSum as = new ArrSum();

as.input();

as.display();

}

}
