Question

Create a do-while loop that asks the user to enter two numbers. The numbers should be added and the sum displayed. The loop should ask the user whether he or she wishes to perform the operation again. If so, the loop should repeat; otherwise it should terminate

Sample Run1

Enter two numbers: 3 15

Do you want another operation: Yes

Enter two numbers: 45 56

import java.util.Scanner;


public class App {


	public static void main(String[] args) {
		Scanner input = new Scanner(System.in);
		String answer = "";
		int sum = 0;
		do {
			System.out.print("Enter two numbers: ");
			int number1 = input.nextInt();
			int number2 = input.nextInt();
			sum += number1 + number2;
			input.nextLine();
			System.out.print("Do you want another operation: ");
			answer = input.nextLine();
		} while (answer.compareToIgnoreCase("yes") == 0);
		System.out.println("Sum = " + sum);
		input.close();
	}
