        } else {
            for (int i = 0; i < number; i++) {
                sum += i;
            }
        }
    }

    public static void main(String[] args) {
        Test obj = new Test();
        System.out.println("Red " + obj.sum);
        obj.doCheck(2);
        System.out.println("Orange " + obj.sum);
        obj.doCheck(3);
        System.out.println("Green " + obj.sum);

題解
