我正在开发一个摇摆应用程序,并决定什么是保存大量 JTextField 值的最佳方法。应用程序从某个网络位置读取属性文件。属性文件为每个特定用户提供大约 10-12 个属性,例如 propertyA_1 是用户 1 的属性,propertA_2 是用户 2 的属性。一个属性中将有大约 10-12 个用户,因此它将产生大约 80 个 JTextField 来显示值。每个用户的属性都将显示在 JTabbedPane 上。我现在要做的是,当用户更改每个 JTabbedPane 中显示的任何用户的任何 JTextField 的值并单击“保存”按钮时,应该保存该属性的值。告诉我处理大量 JtextField 的最佳方法是什么。我想有两种方法
- 单击“保存”按钮时,通过从所有 JTextField 获取值来保存属性的每个值。
- 某种方法可以仅获取更改了文本的那些 JTextField 并保存它们的值。
我不确定如何通过选项 2 来做这件事。但我认为这是最好的方法。
这是我的代码:

JButton saveButton = new JButton("Click to Save");
/**
* @param args the command line arguments
*/

buttonPanel.add(saveButton);
