我正在嘗試創(chuàng)建一個在 Java 中模擬骰子游戲的程序。有兩名玩家每輪擲 3 個骰子，共 6 輪。不同的數(shù)字給每個玩家不同的分數(shù)，這些分數(shù)在每一輪中累積。我需要幫助弄清楚如何增加回合數(shù) - 老實說，我認為我的整個事情都是一團糟，但我希望這能讓我走上正軌。我嘗試過的內(nèi)容顯示在我的代碼中。基本上，我可以為三個骰子生成擲骰并計算擲骰的分數(shù)，但是當我必須隔離到一個單輪然后添加這些輪時，我會卡住。您可以在我的評論中看到我的問題所在：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 方法中編寫這個（int roundNumber），以便我可以在這里將它用作 1 到 6 之間的數(shù)字并在其他方法中逐輪增加它？[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; 在這里，我需要顯示來自 playOneRound() 的打印語句，但我需要每輪更改它并增加分數(shù)問題：1. 顯示三個卷 (abc)，2. 增加輪數(shù)，3. 每輪加分.}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}}我的代碼沒有崩潰（主要是因為我無法編寫任何代碼來解決我的問題），但它確實說 int roundNumber 沒有初始化（這是我的另一個問題）。我是 Java 的新手，我知道這可能是一個相當愚蠢的問題 - 感謝您抽出寶貴的時間！

你的代碼是一團糟。我已將其重新編碼為接近您的代碼并添加了解釋。我希望你能理解并從我的代碼中學習。隨時發(fā)表評論以進行澄清。此外，您可能想學習 Java 基礎知識。
