java - while 循环内的 if/else 语句

Question

我编写了一个游戏代码，模拟用户和计算机掷骰子，获胜者从失败者那里获得 1 美元，每人从 2 美元开始。代码运行良好，但当用户或计算机达到 0$ 时，它不会像我预期的那样结束。有什么建议吗？

import java.util.Scanner;

public class ALE_04_RollDice {
public static void main (String[] args) {

    Scanner input = new Scanner(System.in);
    int userMoney = 2;
    int compMoney = 2;
    int userRoll = (int) (1 + Math.random() * 6);
    int compRoll = (int) (1 + Math.random() * 6);

    System.out.print("Press 'r' if you would like to roll ");
    do {String roll = input.nextLine();
    if (roll.equals("r")); {
        if (userRoll > compRoll){
            userMoney++;
            compMoney--;
     System.out.print("The computer rolled " + compRoll + " and you rolled "       + userRoll + ". you won."
        + "\n" + "You have $" + userMoney + " & The computer has $" + compMoney);
            }

            else if (userRoll < compRoll) {
                compMoney++;
                userMoney--;
                System.out.print("The computer rolled " + compRoll + " and you rolled " + userRoll + 
                        ". you lost" + "\n" + "You have $" + userMoney + " & The computer has $" + compMoney);
            }

            else {System.out.print("The computer rolled " + compRoll + "and you rolled " + userRoll + 
                    ". it's a tie" + "\n" + "You have $" + userMoney + " & the computer has $" + compMoney);}


            }
            }while (userMoney >= 0 || compMoney >=0);
    }}

您的 while 语句正在测试 <= 0，但最初两个变量都 > 0。 while 循环永远不会触发。
