		String answer = "";
		do {
			System.out.print("Enter the first number: ");
			int number1 = input.nextInt();
			System.out.print("Enter the second number: ");
			int number2 = input.nextInt();
			double sum = number1 + number2;
			System.out.println("Sum = " + sum);
			input.nextLine();
			System.out.print("Do you wish to perform the operation again? (y/n): ");
			answer = input.nextLine();
		} while (answer.compareToIgnoreCase("y") == 0);
