猪的游戏：为什么代码不工作或编译，我做错了什么？

引言猪的游戏：为什么代码不工作或编译，我做错了什么？

一个循环的做法。这个计划将会涉及到前一个。

对于这个程序，你将创建一个模拟骰子游戏猪。

该游戏的目标是让玩家在对手之前获得100分，其他细节将在任务中讨论。

在这种情况下，对手将是电脑。

任务1

这个游戏需要两个6面骰子。你需要用随机数发生器模拟这些骰子。

两个骰子（随机数生成器）必须：1-6 之间

农产品值具有140L和340L的种子，分别为模具和一个模2（用于测试目的）任务2

现在你已经有了骰子，我们可以重复你将要玩的规则。

规则：

对于每一回合，玩家将轮流滚动两个骰子。如果一个骰子没有出现在骰子上，这些值就会加到玩家的总数上。然后他们可以选择再次掷出（选择0）或将转牌传给其他玩家（选择1）。如果某个骰子出现1，则该玩家在整个回合中获得的总积分不得增加，并成为其他玩家的回合（前一回合获得的积分将依然存在于其总数中）。如果玩家掷出两个1s，则玩家的回合结束并且他们的总数被重置为0. 您需要一个随机数字生成器来确定计算机（0）或玩家（1）是否会先玩。这也将被用来模拟计算机的选择，以再次滚动或通过翻转。这台发电机的种子将是140L。

假定来自用户的有效输入。

输出应该

以下所有用户提示应该类似于语句“猪的博弈欢迎”开头：

轮到你了（目前积分：0）您推出3和2，分获得本回合：5 按0再次或1卷启动电脑的回合和所有计算机的提示应该是这样的：

电脑的回合（当前点：0）电脑推出1和4，没有点赚取的轮到你他们宣布哪个玩家的回合和当前分数。这是由什么播放器，然后

如果分荣获推出

然后是数字，显示赢得了该轮（看到用户的提示2号线）如果一个被轧总积分，宣布获得无分，接下来的玩家回合（见电脑提示2号线）如果同时的，利用显示消息“取其播放器/卷起两个1 /，点重置和/对手的/转”

“这个程序会比以前更复杂..”，请为我做作业吗？看起来你并没有付出太多努力，甚至试图自己先解决问题。即你在哪里开始和失败？ –

现在我可以添加代码。对不起，以前，它不会让我。 – Muhammad

我确实试图首先自己解决问题。现在我能够发布我的代码，可以看到我开始和失败的位置。 – Muhammad

行if (playerTotal > computerTotal)之前有一个花括号太多。删除一个，结构应该没问题。问题在于，如果你在最后一条if语句之前关闭了方法，那么该语句基本上不在Java中允许的方法之外。如果您使用IDE，它应该向您显示。

谢谢，但现在它说：计划产生太大的输出。输出限制为50000个字符。检查程序是否有任何未终止的循环产生输出。 – Muhammad

@Muhammad，您正在为您的项目使用IDE吗？ –
