我正在尝试制作一个非常基本的 Black Jack 游戏,我将其分为三个简单的类,但我对 Java 非常陌生,而且我是一个糟糕的编码员,但我需要学习这个才能工作。我在理解如何调用方法和类时遇到了一些重大困难。我弄清楚了游戏的基本结构,例如如何创建卡牌以及如何进入游戏和退出游戏。我只是无法弄清楚游戏本身。这就是我到目前为止所创建的。请提供任何建议和方向,以便我能理解这会很棒,我很绝望。
BlackJack.java
import java.util.*;
public class BlackJack4 {
public static void main(String[] args) {
// write your code here
Scanner keyboard = new Scanner(System.in);
Scanner scan = new Scanner(System.in);
String playGame = "";
System.out.print("Wanna play some BlackJack? \n");
System.out.print("Type yes or no \n");
playGame = keyboard.nextLine();
if (playGame.equals ("yes"))
{
/*
This is the area I need help in figuring out.
*/
}
else if (playGame.equals("no")) //Player decided to no play the game
{
System.out.print("Thank you for playing with us today.\n");
System.out.print("To exit the game please press enter.");
scan.nextLine();
System.exit(0);
}
else
{
System.out.print("Sorry you did something wrong. Please try again.\n");
System.out.print("To exit the game please press enter.");
scan.nextLine();
System.exit(0);
}
}
}
Deck.java
import java.util.*;
public class Deck {
ArrayList<Cards> cards = new ArrayList<Cards>();
String[] Suits = { "Clubs", "Diamonds", "Hearts", "Spades"};
String[] Ranks = {null, "A", "2", "3", "4", "5", "6", "7", "8", "9", "10", "J", "Q", "K"};
public Deck() {
int d = Suits.length * Ranks.length;
String[] deck = new String[d];
for (int i = 0; i < Ranks.length; i++) {
for (int j = 0; j < Suits.length; j++) {
deck[Suits.length * i + j] = Ranks[i] + " of " + Suits[j];
}
}
}
public void shuffle(){//shuffle the deck when its created
Collections.shuffle(this.cards);
}
}
Cards.java
public class Cards {
private String suit;
private String rank;
public Cards(){}
public Cards(String suit, String rank){
this.suit = suit;
this.rank = rank;
}
public String getSuit(){
return suit;
}
/* public void setSuit(String suit){
this.suit = suit;
}*/
public String getRank(){
return rank;
}
/*
public void setRank(String value){
this.rank = rank;
}*/
@Override
public String toString() {
return String.format("%s of %s", rank, suit);
}
}
最佳答案
这种任务不是很容易的关卡,这里有很多事情要做,也许你必须从一些更基础的东西开始。但如果你确定要通过,这里有一些建议和代码:
您必须将 score
字段添加到 Card 类(类的单个名称比复数名称更好,变量的首字母小写,这是一些代码约定)。这并不容易,因为 Ace 可以具有多值。
使用 LinkedList 而不是 ArrayList 作为 Deck.cards。荷官每次轮询一张牌,这与真实游戏更相似。
将 this.cards.add(cards);
替换为 'deck[Suits.length * i + j] = Ranks[i] + "of "+ Suits[j];'你根本不需要这个字符串数组。最重要的部分是你可以将骨架放在你所指的地方,最需要帮助的地方:
private static void playGame(Scanner scan) {
Deck deck = new Deck();
String playGame;
Integer yourScore = 0;
Random random = new Random();
Boolean playerEnough = false;
Boolean dealerEnough = false;
Integer dealerScore = 0;
deck.shuffle();
while ((yourScore <= 21 && dealerScore <= 21) && (!dealerEnough || !playerEnough)) {
if (yourScore == 0) {
yourScore += getCardScore(deck, "Player");
yourScore += getCardScore(deck, "Player");
}
if (dealerScore == 0) {
dealerScore += getCardScore(deck, "Dealer");
dealerScore += getCardScore(deck, "Dealer");
}
if (!playerEnough) {
System.out.println("Want a card?");
playGame = scan.nextLine();
if (playGame.equals("yes")) {
yourScore += getCardScore(deck, "Player");
} else {
System.out.println("PlayerDone");
playerEnough = true;
}
}
if (!dealerEnough) {
if (random.nextBoolean()) {
dealerScore += getCardScore(deck, "Dealer");
} else {
System.out.println("DealerDone");
dealerEnough = true;
}
}
System.out.println(yourScore + " [p] : [d] " + dealerScore);
}
// decide who is a winner
}
private static Integer getCardScore(Deck deck, String who) {
System.out.print(who + " given: ");
Cards cards = deck.cards.pollFirst();
System.out.println(cards);
return cards.getScore();
}
这可以帮助你更进一步,或者不行,那么我建议你解决一些较小的练习。
