Java Program: Count and Sum of Numbers Divisible by 17

17. Write a program to find the number of and sum of all integers greater than 500 and less than 1000 that are divisible by 17.

import java.util.Scanner;
 
public class DivisibleBy17 {
    public static void main(String[] args) {
 
        int count = 0;
        int sum = 0;
 
        // Check numbers from 501 to 999
        for (int i = 501; i < 1000; i++) {
            if (i % 17 == 0) {
                count++;
                sum += i;
            }
        }
 
        // Output
        System.out.println("Number of integers divisible by 17 = " + count);
        System.out.println("Sum of integers divisible by 17 = " + sum);
    }
}

Number of integers divisible by 17 = 29
Sum of integers divisible by 17 = 21692

Explanation

• The loop runs from 501 to 999.
• i % 17 == 0 checks if the number is divisible by 17.
• count keeps track of how many such numbers exist.
• sum stores the total of these numbers.
• Final results are displayed after the loop ends.
