Answer to Question #268818 in Java | JSP | JSF for Chakalaka

Question

1. LOOPS&CONDITIONS: Create a program that takes in two numbers and then calculate the sum of all even numbers in between the two numbers. The program should also calculate the products of all the odd numbers between the provided numbers.

 

Sample run 1:                                                 

Enter two numbers: 2 8                                                

Output:

Even numbers: 2 4 6 8

Odd numbers: 3 5 7

Sum of even numbers = 20

Product of odd numbers = 105

Answer 1

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter two numbers: ");
        int one = in.nextInt();
        int two = in.nextInt();
        int sum = 0;
        int product = 1;
        StringBuilder oddNumbers = new StringBuilder();
        System.out.print("Even numbers: ");
        for (int i = Math.min(one, two); i <= Math.max(one, two); i++) {
            if (i % 2 == 0) {
                sum += i;
                System.out.print(i + " ");
            } else {
                product *= i;
                oddNumbers.append(i).append(" ");
            }
        }
        System.out.println("\nOdd numbers: " + oddNumbers);
        System.out.println("Sum of even numbers = " + sum);
        System.out.println("Product of odd numbers = " + product);

    }
