如何在Java中初始化变量/增加“回合”次数-入门,需要帮助

[英]How to initialize variable / have increasing “rounds” in Java - Beginner, need assistance

I'm attempting to create a program that simulates a dice game in Java. 我试图创建一个程序来模拟Java中的骰子游戏。 There are two players that roll 3 dice each round, for six rounds. 有两个玩家每轮掷3个骰子,持续6个回合。 Various numbers give various points to each player, which accumulate each round. 不同的数字会给每个玩家不同的分数,这些分数会在每个回合中累积。

I need help figuring out how to have increasing rounds - Honestly, I think my entire thing is a mess, but I'm hoping this will get me on the right track. 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一团糟,但是我希望这能使我走上正确的道路。

What I've tried is shown in my code. 我尝试过的内容显示在我的代码中。 Basically, I can generate rolls for the three dice and calculate the score for the roll, but I get stuck when I have to isolate to a single round, and then add those rounds. 基本上,我可以为三个骰子生成掷骰,并计算掷骰的得分,但是当我不得不隔离到一个回合然后加进这些回合时,我陷入了困境。

You can see where I have trouble in my comments, found in: method getScore() and method playBunco(). 您可以在方法中找到我遇到麻烦的地方:方法getScore()和方法playBunco()。

[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; 

How do I write this (int roundNumber) in the main method so I can use it in here as a number between 1 and 6 & increase it round by round in other methods? 如何在主要方法中编写此(int roundNumber),以便可以在此处将其用作1到6之间的数字,并在其他方法中逐个增加?

[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; 

Here, I need to display the print statement from playOneRound(), but I need to change it each round with an increasing score PROBLEMS: 1. displaying the three rolls (abc), 2. Having increasing rounds, 3. adding points each round. 在这里,我需要显示playOneRound()的打印语句,但是我需要在每个回合中以增加的分数来更改它。问题:1.显示三卷(abc),2.增加回合,3.每个回合添加点。

}

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
}

} }

My code isn't crashing (mainly because I couldn't write any to solve my problem), but it does say that int roundNumber is not initialized (which is my other problem). 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),但是它确实说int roundNumber未初始化(这是我的另一个问题)。

I'm very new at Java, and I know this might be a rather dumb question - Thank you for taking the time! 我是Java的新手,我知道这可能是一个愚蠢的问题-感谢您抽出宝贵的时间!
