java - 如何返回我的 getWin 并不仅仅是 true 或 false

Question

我试图让我的程序采用多个不同的返回语句，这样我就可以有一个胜利分割和失败，而不仅仅是胜利或失败，而且似乎不知道如何做到这一点。我的程序是为了让你赢或者让你的赌注加倍而设计的。如果打平了，你就可以拿回你的钱。如果你输了，你就输了你的赌注。我之前曾通过使用 boolean 值并返回 true 或 false 来获得胜利和失败，但需要一种方法来添加进行分割的方法。

我已经尝试了网上看到的多种方法，但都没有效果，我们将不胜感激。

//Import Random Number Generator
import java.util.Random;

   //Keep the data secure by using private

}//end class

我希望能够得到不同的返回语句，这样我实际上可以将胜利方面设置为失败方面，但如果两个玩家平局，也可以设置 split 方面。

Answer 1

您需要返回三个结果，分别是:获胜、失败和平局，对吗？

在这种情况下，您必须使用三个不同的变量，例如，

public String Win = "Win",Lose = "Lose",Split = "Split"; 

并使用其他变量来存储结果，例如result，并在getWin()中返回该结果。参见下面的代码:

import java.util.Random;
import java.util.Scanner;
class BlackJackPlayer{
   //Keep the data secure by using private
   private String hand;
   private int sum;
   private int numAces;
   private static Random gen = new Random();
   public String Win = "Win",Lose = "Lose",Split = "Split";
   private String result = "";
   private final int ACE = 1;
   private final int JACK = 11;
   private final int QUEEN = 12;
   private final int KING = 13;

   //constructor
   public BlackJackPlayer(){
      hand = "";
      sum = 0;
      numAces = 0;
   }

   //Getter for hand variable
   public String getHand(){
      return hand;
   }

   public String setHand(){
      hand = " ";
      return hand;
   }

   //Getter for sum variable
   public int getSum(){
      return sum;
   }

   public void hit(){
      //local variable
      int currentCard = gen.nextInt(13) + 1;

      if(currentCard > ACE && currentCard < JACK){
         sum += currentCard;
         hand += currentCard + "   ";
      }
      else if(currentCard == ACE){
         sum += 11;
         numAces++;
         hand += "A  ";
      }

      else if(currentCard == QUEEN){
         sum += 10;
         hand += "Q  ";
      }

      else if(currentCard == QUEEN){
         sum += 10;
         hand += "Q  ";
      }

      else if(currentCard == KING){
         sum += 10;
         hand += "K  ";
      }//Ends Else If

      //Is Ace 1 or 11
      if(sum > 21 && numAces > 0){
         numAces--;
         sum -= 10;
      }

    }//ENDS HIT

   public String getWin(BlackJackPlayer other) {
      if(sum > 21){
         result = Win;
      }
      else if(sum < other.getSum()){
          result = Lose;
      }
      else if(sum == other.getSum()){
          result = Split;
      }
   return result;
  }
}//end main

class BlackJackGame{
    public static void main(String args[]){
       BlackJackPlayer you = new BlackJackPlayer();
       BlackJackPlayer enemy = new BlackJackPlayer();
       int chips = 100,bet,winnings,multiply = 2;
       String qORc;
       Scanner in = new Scanner(System.in);

       String choice;
       do{
          you.setHand();

          while(enemy.getSum() < 16){

          String result = you.getWin(enemy);
