Question

Write a java program that reads from the user two integers n1 & n2, in order to display the
numbers between n1 and n2 (both included) that are multiple of 3, and display their count.

Answer 1

Answer:

import java.util.*;

public class Main

{

public static void main(String[] args) {

    ArrayList<Integer> list = new ArrayList<Integer>();

    int threes = 0;

 System.out.print("Enter a number:");

 Scanner sc = new Scanner(System.in);

 int n1 = sc.nextInt();

 System.out.print("Enter another number:");

 int n2 = sc.nextInt();

 System.out.println("The numbers divisible by 3 between " + n1 + " and " + n2 + " are-");

     for(int i = n1; i < n2; i++){

         if(i%3 == 0){

             list.add(i);

             threes++;

         }

     }

     for (int i : list){

         System.out.println(i);

     }

     System.out.println("The count of numbers divisible by 3 is: " + threes);

}

}
