我刚试过这个，但在最后一个括号里，我得到一个错误，说解析时到达了文件的末尾。知道为什么吗？好吧，我忘了文件末尾的括号。我修正了那个错误。但当我添加事件句柄时，当我按下calculate方法的按钮ADD@FXML注释时，仍然没有发生任何事情，如果它不起作用，请将代码片段复制到initialize方法中。您正在使用FXML。您应该通过FXML定义一个onAction事件，就像我链接的问题注释中所定义的一样，它可能与我无法再找到的上一个问题重复。我将再次链接它。如果您不理解，请阅读文档：。您永远不会在链接到FXML的现有事件处理程序中定义新的setOnAction事件处理程序。@DaveParal我尝试添加注释，但仍然没有得到任何结果。我需要在另一个文件的main方法中添加一些内容吗？或者还有其他问题吗？要想知道按钮是否真的启动了，你只需输入一个System.out.println你只需按下按钮；在顶部的calculateTotal处理程序中。如果您在按下按钮后看到此代码，您就知道按钮正在启动，您的问题在其他地方。要尝试查看代码是否抛出了未捕获的错误，请将所有代码放在一个try块中，然后在catch框中使用Exception ex并打印ex.toString；
