java - 为操作监听器提供字符串质量并在 if 语句中使用这些字符串

Question

作为一种自学 Action 监听器、按钮和 Jframe 的副项目，我开始使用一些基于电视节目等的分析器。按钮和 Action 监听器可以工作，但我只是不知道如何为 Action 监听器提供字符串并调用这些字符串。我哪里错了？预先感谢您。

Answer 1

因为您将唯一的调用放在主线程中，所以您所做的就是在框架和所有监听器设置完毕后调用 GiveRecommendation 方法。

虽然您的操作监听器将正确设置本地字符串的值，但它们不会执行其他操作。

因此，如果您想调用 GiveRecommendation 方法，请将其放置在现有的操作监听器之一中，或者创建一个新的按钮和操作监听器。
