Question

Write a java application to input 2 positive integers X and Y such that X is less than Y.
Then the program should do the following:
1. Output the sum of even integers between 1 and X.
2. Output the average of odd integers between 1 and Y.
3. Output the common divisors of X and Y.

Given below is the code for the question. Please do rate the answer if it helped. Thank you.

MyNumbers.java
======
import java.util.Scanner;

public class MyNumbers {
   public static void main(String[] args) {
       int X, Y;
       int evenSum = 0;
       double oddAverage =0 ;
       int count = 0;
       Scanner in = new Scanner(System.in);

       System.out.print("Enter X: ");
       X = in.nextInt();
      
       System.out.print("Enter Y: ");
       Y = in.nextInt();
      
       for(int i = 1; i <= X; i ++) {
           if(i % 2 == 0)
               evenSum += i;
       }
       System.out.println("Sum of even numbers between 1 and " + X + " = " + evenSum);
      
      
       for(int i = 1; i <= Y; i++) {
           if(i % 2 == 1) {
               oddAverage += i;
               count++;
           }
       }
      
       oddAverage = oddAverage / count;
       System.out.println("Average of odd numbers between 1 and " + Y + " = " + oddAverage);
      
       System.out.println("Common diviors of " + X + " and " + Y);
       for(int i = 1; i <= X && i <= Y; i++) {
           if(X % i == 0 && Y % i == 0)
               System.out.print(i + " ");
       }
       System.out.println();
   }
}

output
====
Enter X: 12
Enter Y: 15
Sum of even numbers between 1 and 12 = 42
Average of odd numbers between 1 and 15 = 8.0
Common diviors of 12 and 15
