Java 从CSV读取以填充包含复选框和字符串的tableview

我有一个JavaFX桌面应用程序，我正在尝试更新/重新创建，我在读取csv和填充包含复选框列和字符串列的tableview时遇到问题

在使用上面的布尔值（false）和csv文件中字符串的第二部分创建之前，我尝试在第91-92行设置列行的布尔值，但这会导致错误：“无法将BooleanProperty转换为boolean”

我还尝试通过将其添加到第1列的csv中来设置false，即：

虚假的；“NameString1”（换行符） 虚假的；“NameString2”等这将导致程序运行，但列表为空

我希望上面在第一列中用一个未选中的复选框和csv中的相关名称字符串填充tableView

它应该像下面的例子一样工作，除了在csv内设置初始值false不是一个要求：

如果我删除csv inputstream并使用上面的方法填充表格，那么一切都正常工作

有什么想法吗？最好在csv中添加'false'还是修复BooleanProperty>boolean问题？我已经阅读并测试了一些东西，如.booleanValue（），.getValue（）

非常感谢所有人和这个伟大的社区！！

错误是我试图从一个我不应该的目录编译控制器。我现在已经让csv读取工作和一个全选复选框工作。目前我正在处理表列复选框的侦听器，以便显示关于哪个组h的状态消息已选定的对象及其布尔值

好的，我能让它像这样工作：
