JetBrain [Easy] Simply Chatty Bot 만들기 - Stage 5

드디어 첫번째 프로젝트 마지막 스테이지 !

이번 task는 문제를 내고 맞히면 축하한다는 메세지를 틀리면 다시 하라는 메세지를 보내는 코드를 작성하는것이다.

 

import java.util.Scanner;

class ChatBot {
    final static Scanner scanner = new Scanner(System.in); // Do not change this line

    public static void main(String[] args) {
        greet("Aid", "2018"); // change it as you need
        remindName();
        guessAge();
        count();
        test();
        end();
    }

    static void greet(String assistantName, String birthYear) {
        System.out.println("Hello! My name is " + assistantName + ".");
        System.out.println("I was created in " + birthYear + ".");
        System.out.println("Please, remind me your name.");
    }

    static void remindName() {
        String name = scanner.nextLine();
        System.out.println("What a great name you have, " + name + "!");
    }

    static void guessAge() {
        System.out.println("Let me guess your age.");
        System.out.println("Enter remainders of dividing your age by 3, 5 and 7.");
        int rem3 = scanner.nextInt();
        int rem5 = scanner.nextInt();
        int rem7 = scanner.nextInt();
        int age = (rem3 * 70 + rem5 * 21 + rem7 * 15) % 105;
        System.out.println("Your age is " + age + "; that's a good time to start programming!");
    }

    static void count() {
        System.out.println("Now I will prove to you that I can count to any number you want.");
        int num = scanner.nextInt();
        for (int i = 0; i <= num; i++) {
            System.out.printf("%d!\n", i);
        }
    }

    static void test() {
        System.out.println("Let's test your programming knowledge.");
        // write your code here
        System.out.println("Why do we use methods?");
        System.out.println("1. To repeat a statement multiple times.");
        System.out.println("2. To decompose a program into several small subroutines.");
        System.out.println("3. To determine the execution time of a program.");
        System.out.println("4. To interrupt the execution of a program.");
        int choice = scanner.nextInt();
        while(choice != 2){
            System.out.println("Please, try again");
            choice = scanner.nextInt();
        }
    }

    static void end() {
        System.out.println("Congratulations, have a nice day!"); // Do not change this text
    }
}

오늘 풀었던 부분은  test() function 인데 정답을 맞출 때 까지 while roop 를 돌려주는게 핵심이었다.

static void test() {
        System.out.println("Let's test your programming knowledge.");
        // write your code here
        System.out.println("Why do we use methods?");
        System.out.println("1. To repeat a statement multiple times.");
        System.out.println("2. To decompose a program into several small subroutines.");
        System.out.println("3. To determine the execution time of a program.");
        System.out.println("4. To interrupt the execution of a program.");
        int choice = scanner.nextInt();
        while(choice != 2){
            System.out.println("Please, try again");
            choice = scanner.nextInt();
        }
    }
