无法让我的代码重复问题让游戏继续

Question

我必须为我正在服用的 class 编写代码。这是一款基于投注 2 种颜色和 1 - 36 数字的游戏。用户已经给了他们一定数量的筹码，即 100。我已经编写了大部分代码，但是，我无法获得我的重复该过程的代码。我目前正在使用 Do-While 循环。但这就是行不通。

这是我的代码：

import java.util.Scanner;
import java.lang.Math;

public class Program_8 {
    public static void main(String[] args) {
        Scanner userInput = new Scanner(System.in);
        int chipsNow = 100;
        int userChoice;
        int chipsBetted = 0;
        
        
        //welcome message
        welcome();  
        
        do {
            
            
            int spinNum = (int)(Math.random() * 36) + 0;
            userChoice = getMenuChoice(userInput);
            
            //get user choice
            if (userChoice == 1) {
                int getNum = getNumber(userInput);
                int getBet = getBet(userInput, chipsNow);
                String determineColor = determineColor(spinNum);
                
                System.out.println("\nSpinning Wheel....");
                System.out.println("Spin Number: " + spinNum);
                System.out.println("Spin Color: " + determineColor);
                
                if (getNum == spinNum) {
                    
                    chipsNow += getBet;
                    chipsBetted += getBet;
                    System.out.println("Congrats, you won!");
                    System.out.println("\nYou now have: " + chipsNow + " chips");
                    ;
                }
                
                else {
                    chipsNow -= getBet;
                    
                    System.out.println("\nSorry, you lost!");
                    System.out.println("You now have: " + chipsNow + " chips");
                    
                }
            }
            
            if (userChoice == 2) {
                String getColor = getColor(userInput);
                int getBet = getBet(userInput, chipsNow);
                String determineColor = determineColor(spinNum);

                if (getColor.equals(determineColor)) {

Answer 1

所以只看代码我会：

在 do while 之外声明 int userChoice = 0;。这是 while 条件起作用所必需的。
welcome(); 和 userChoice = getMenuChoice(userInput); 应该进入 do while 因此它将重复欢迎消息并要求用户选择在执行时执行的所有操作
像这样简化你的 while 循环 while(userChoice != 3 && chipsNow > 0)。这只是为了使其更具可读性。
最后删除 if(getNum == spinNum) { } else { } 中的 break;。 break 将强制退出 while 循环，而不管 while 条件是否满足。所以基本上，如果你赢了或输了一场比赛，你的循环就会退出，我认为这不是你想要的。您只希望在 chipsNow < 0 或 userChoice == 3
时退出循环
