豬的遊戲：爲什麼代碼不工作或編譯，我做錯了什麼？

引言豬的遊戲：爲什麼代碼不工作或編譯，我做錯了什麼？

一個循環的做法。這個計劃將會涉及到前一個。

對於這個程序，你將創建一個模擬骰子游戲豬。

該遊戲的目標是讓玩家在對手之前獲得100分，其他細節將在任務中討論。

在這種情況下，對手將是電腦。

任務1

這個遊戲需要兩個6面骰子。你需要用隨機數發生器模擬這些骰子。

兩個骰子（隨機數生成器）必須：1-6 之間

農產品值具有140L和340L的種子，分別爲模具和一個模2（用於測試目的）任務2

現在你已經有了骰子，我們可以重複你將要玩的規則。

規則：

對於每一回合，玩家將輪流滾動兩個骰子。如果一個骰子沒有出現在骰子上，這些值就會加到玩家的總數上。然後他們可以選擇再次擲出（選擇0）或將轉牌傳給其他玩家（選擇1）。如果某個骰子出現1，則該玩家在整個回合中獲得的總積分不得增加，併成爲其他玩家的回合（前一回合獲得的積分將依然存在於其總數中）。如果玩家擲出兩個1s，則玩家的回合結束並且他們的總數被重置爲0. 您需要一個隨機數字生成器來確定計算機（0）或玩家（1）是否會先玩。這也將被用來模擬計算機的選擇，以再次滾動或通過翻轉。這臺發電機的種子將是140L。

假定來自用戶的有效輸入。

輸出應該

以下所有用戶提示應該類似於語句「豬的博弈歡迎」開頭：

輪到你了（目前積分：0）您推出3和2，分獲得本回合：5 按0再次或1卷啓動電腦的回合和所有計算機的提示應該是這樣的：

電腦的回合（當前點：0）電腦推出1和4，沒有點賺取的輪到你他們宣佈哪個玩家的回合和當前分數。這是由什麼播放器，然後

如果分榮獲推出

然後是數字，顯示贏得了該輪（看到用戶的提示2號線）如果一個被軋總積分，宣佈獲得無分，接下來的玩家回合（見電腦提示2號線）如果同時的，利用顯示消息「取其播放器/捲起兩個1 /，點重置和/對手的/轉」

「這個程序會比以前更復雜..」，請爲我做作業嗎？看起來你並沒有付出太多努力，甚至試圖自己先解決問題。即你在哪裏開始和失敗？ –

現在我可以添加代碼。對不起，以前，它不會讓我。 – Muhammad

我確實試圖首先自己解決問題。現在我能夠發佈我的代碼，可以看到我開始和失敗的位置。 – Muhammad

行if (playerTotal > computerTotal)之前有一個花括號太多。刪除一個，結構應該沒問題。問題在於，如果你在最後一條if語句之前關閉了方法，那麼該語句基本上不在Java中允許的方法之外。如果您使用IDE，它應該向您顯示。
