Java 当我运行两个类时，我的老鼠没有移动

我有一节迷宫课和一节老鼠课。它们都使用9个字符的字符串协议和套接字进行通信，老鼠告诉迷宫它想如何移动。迷宫移动它。为了显示老鼠正在我的迷宫中移动，我将迷宫路径的背景色设置为红色 每次老鼠在特定的路径上移动。但是，出于某种原因，这并没有发生。我完全不知道为什么。请帮忙

我看到的主要问题是在ratMessage方法中，您正在比较字符串值和字符

这是行不通的，因为字符串和字符永远不可能相等，它们是错误的类型。如果相反，你把它们改成更像

if (r2.equals("r"))

你应该有更多的成功

还有很多其他的陷阱会引起一些悲伤。静态不是解决方案。过度使用静电会回来狠狠地咬你。在可能的情况下，您应该依赖于传递需要与之交互的对象的有效引用

就我个人而言，我会设计一系列描述预期合同的接口，例如ratMessage。您的UI将实现这个接口，它的引用应该传递给主comms类，该类从rat读取信息

您也违反了Swing的单线程规则。Swing要求对任何UI组件的所有交互和更新必须在事件调度线程的上下文中完成。因为您正在从主线程运行主循环，并调用ratMessage，然后更新按钮，所以您违反了此规则

请查看和以了解更多详细信息

该解决方案可能涉及一个SwingWorker以实现简单性或SwingUtilities.invokeLater以实现快速更改…

您首先违反了ratMessage方法中Swing的单线程规则

if (r2.equals('r'))

if (r2.equals("r"))
