숫자 2개를 받아서 합을 출력하는 간단 예제

public class Main {

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        int sum = 0;
        String input;
        int integer;
        String input_temp;

        while(true){
            input = scanner.nextLine();
            input_temp = input;


            if(input_temp.contains("exit")){
                break;
            }

            Scanner scannerDivider = new Scanner(input).useDelimiter(" ");

            while(scannerDivider.hasNext()){
                integer = scannerDivider.nextInt();
                sum += integer;
            }
            System.out.println(sum);
