使用命令行界面创建 Black Jack 游戏

Question

我的 Java 1 class 中有一个作业。它是创建一个带有命令行界面的 Black-Jack 游戏。

但是我的书只有一页专门介绍命令行参数。这个项目是一个额外的功劳，所以我想我们应该去别处寻找这个信息。我已经完成了我的程序。它运行并工作。我敢肯定我的代码对于已经这样做了一段时间的任何人来说都会显得笨拙。

任何人都可以就这个主题启发我，主题是命令行界面吗？

这是我的代码：

package blackjack;

import java.util.Scanner;

public class BlackJack {

public static void main(String[] args) {
    boolean play = true;

    while (play == true) {
        Game game1 = new Game();
        Scanner keyboard = new Scanner(System.in);
        Deck deck1 = new Deck();
        deck1.createDeck();
        deck1.shuffleDeck(deck1.getDeck1());
        game1.setDeck(deck1.getDeck2());
        System.out.println("Welcome to BLACKJACK!");
        System.out.println("------------------------");
        System.out.println("Enter 1 to Start: ");
        int start = keyboard.nextInt();

        if (start == 1) {
            deck1.createDeck();
            System.out.println("Shuffling Deck");
            deck1.shuffleDeck(deck1.getDeck1());
            System.out.println("Shuffling Deck");
            System.out.println("Shuffling Deck");
            System.out.println("Shuffling Deck");
            System.out.println("Shuffling Deck");
            System.out.println("Shuffling Deck");

            System.out.println("Lets Play!");

            game1.dealOneCardPlayer(game1.getCardCounter());
            game1.setCardCounter(game1.getCardCounter() + 1);
            game1.dealOneCardPlayer(game1.getCardCounter());
            game1.setCardCounter(game1.getCardCounter() + 1);
            game1.dealoneCardDealer(game1.getCardCounter());
            game1.setCardCounter(game1.getCardCounter() + 1);
            game1.dealoneCardDealer(game1.getCardCounter());
            game1.setCardCounter(game1.getCardCounter() + 1);
            game1.check();
        }

        while (game1.isEndGame() == false) {
            game1.displayPlayer();
            game1.turnLoop();

        }
        if (game1.isEndGame() == true) {
            System.out.println("FINAL HANDS");
            System.out.println("");
            game1.displayPlayer();
            System.out.println("");
            System.out.println("Do you want to Play again? 1 = yes or 2 = no");
            int answer = keyboard.nextInt();
            if (answer == 1) {
                play = true;
            } else if (answer == 2) {

Answer 1

我认为这里 "command line interface" 的意思是命令行参数和从 System.in 读取并写入 System.out 的混合。也就是说，用户可以通过命令行终端或 window 与程序交互。

此外，它可能暗示用户通过 window 发出命令，程序在从 System.in 读取后解释这些命令。

我想这里的术语 "command" 可以按照您喜欢的方式进行解释，但您可能知道您的导师会期望什么。
