java - 石头、剪刀、布游戏无法正确记录分数

Question

我的石头剪刀布游戏遇到问题。当我玩游戏时，它会将胜利或失败记录为胜利和失败。我试图让它记录一场胜利和一场失败，并且不会为胜利和失败添加分数。有什么建议吗？

import java.io.*;

public class RPS {
    static BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
    static int x;

    public static void main(String[] args) throws IOException {

        int choice;
        do {
            System.out.println("Game Menu");
            System.out.println("---------------------------------------------");
            System.out.println("1. Start Game");
            System.out.println("2. Quit Program");

            choice = Integer.valueOf(in.readLine()).intValue();

            if(choice == 1) {
                System.out.println("Welcome to Rock, Paper, Scissors");
                System.out.println("---------------------------------------------");
                System.out.println("Please enter Rock, Paper or Scissors to play");

            int wins = 0, loss = 0, ties = 0;
            String user = in.readLine();

您需要用大括号:{} 括住缩进的条件代码。与 Python 等语言不同，Java 中的缩进没有语义意义。

例如。

if (comp.equals("Rock"))
    System.out.println("Paper beats rock, congrats you win!");
    wins++;

等同于:

if (comp.equals("Rock")) {
    System.out.println("Paper beats rock, congrats you win!");
}
wins++;

即wins 无条件递增。

尝试:

if (comp.equals("Rock")) {
    System.out.println("Paper beats rock, congrats you win!");
    wins++;
}
