我有一个主要是调查的GUI，当调查完成后，信息将被提取到一个表中，我目前无法获取所有信息，我创建了一个名为finish处理程序的Actionlistener，它附加到调查表中GUI按钮“完成”所以当单击完成按钮时，它将提取所有信息并将其存储到我的DataStorage类中。下面是我的调查GUI，actionListener类和数据存储类。

你去过的设计非常健谈。当您只需将其设置为FinishHandler时，您已为每个小部件附加了新的btnFinish。您设置的方式，对于GUI中的每个更改，您将更新DataStorage对象。相反，只需将其添加到btnFinish，您就可以减少处理程序被调用的次数，并可以简化您的过程。当然，您需要整合itemStateChanged和actionPerformed方法。这样，您就可以选择在进入DataStorage时初始化actionPerformed对象，然后可以启动持久性过程。在研究将数据从内存移动到存储时，请查看SwingWorker和concurrency in Swing周围的概念。
编辑：
通过'合并您的itemStateChanged和actionPerformed方法，'我的意思是将您的所有数据收集复选到您执行的操作方法中。这样，当您单击完成按钮时，您可以收集DataStorage对象所需的所有数据。
