Question

Program Name: Divisible.

Write a program that calculates the number of integers in a range from 1 to some user-specified upper bound that are divisible by 3, the sum of those integers, and the number and sum of those integers not divisible by 3. Your program must display meaningful output which includes: the selected upper bound number of integers divisible by 3 sum of integers divisible by 3 number of integers not divisible by 3 sum of integers not divisible by 3

Answer 1

Source Code:

import java.util.Scanner;
class Main{
   public static void main(String[] args) {
       Scanner scnr=new Scanner(System.in);
       System.out.print("Enter an upper bound value: ");
       int upper_bound=scnr.nextInt();
       int count_divisible=0,sum_divisible=0;
       int count_notDivisible=0,sum_notDivisible=0;
       for(int i=1;i<=upper_bound;i++){
           if(i%3==0){
               count_divisible=count_divisible+1;
               sum_divisible=sum_divisible+i;
           }
           else{
               count_notDivisible=count_notDivisible+1;
               sum_notDivisible=sum_notDivisible+i;
           }
       }
       System.out.println("No. of Integers divisible by 3 from 1 to "+upper_bound+": "+count_divisible);
       System.out.println("Sum of Integers divisible by 3 from 1 to "+upper_bound+": "+sum_divisible);
       System.out.println("No. of Integers not divisible by 3 from 1 to "+upper_bound+": "+count_notDivisible);
       System.out.println("Sum of Integers divisible by 3 from 1 to "+upper_bound+": "+sum_notDivisible);
   }
