如何在 Java 中初始化变量/增加“轮数” - 初学者,需要帮助

如何在 Java 中初始化变量/增加“轮数” - 初学者,需要帮助

烙印99 2022-06-23 08:55:03
我正在尝试创建一个在 Java 中模拟骰子游戏的程序。有两名玩家每轮掷 3 个骰子,共 6 轮。不同的数字给每个玩家不同的分数,这些分数在每一轮中累积。我需要帮助弄清楚如何增加回合数 - 老实说,我认为我的整个事情都是一团糟,但我希望这能让我走上正轨。我尝试过的内容显示在我的代码中。基本上,我可以为三个骰子生成掷骰并计算掷骰的分数,但是当我必须隔离到一个单轮然后添加这些轮时,我会卡住。您可以在我的评论中看到我的问题所在:getScore() 方法和 playBunco() 方法。[CODE REMOVED FOR BREVITY] public static int diceRoll() {  int roll;  roll = (int)(Math.random() * 6 + 1);   return roll;}public static int getScore() {  diceRoll();   int roundNumber; 我如何在 main 方法中编写这个(int roundNumber),以便我可以在这里将它用作 1 到 6 之间的数字并在其他方法中逐轮增加它?[CODE REMOVED FOR BREVITY]   int score = 0;     if(die1 == roundNumber) {       if(die2 == roundNumber) {        if(die3 == roundNumber) {          score = bunco;        }        else{          score = twoPoints;        }      }      else{        score = onePoint;      }  [CODE REMOVED FOR BREVITY]   return score;}public static void playOneRound() {  diceRoll();   int die1 = diceRoll();   int die2 = diceRoll();   int die3 = diceRoll();   getScore();   int score = getScore();   String player;   for(int roundNumber = 1; roundNumber <= 3; roundNumber ++) {    System.out.println(player + " rolled " + die1 + die2 +     die3 + " and scored " + score + " points");  }}public static void playBunco() {  String player1;   String player2; 在这里,我需要显示来自 playOneRound() 的打印语句,但我需要每轮更改它并增加分数问题:1. 显示三个卷 (abc),2. 增加轮数,3. 每轮加分.}public static void main(String[] args) {  diceRoll();   getScore();  String player1 = (args[0]);   String player2 = (args[1]);   playBunco(); //this is where I just got completely stuck}}我的代码没有崩溃(主要是因为我无法编写任何代码来解决我的问题),但它确实说 int roundNumber 没有初始化(这是我的另一个问题)。我是 Java 的新手,我知道这可能是一个相当愚蠢的问题 - 感谢您抽出宝贵的时间!

你的代码是一团糟。我已将其重新编码为接近您的代码并添加了解释。我希望你能理解并从我的代码中学习。随时发表评论以进行澄清。此外,您可能想学习 Java 基础知识。
