import java.util.Scanner;


public class App {


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