第二次GUI作业

这次的作业使我的提升很大，尤其是树形和列表都是第一次使用，通过查阅API文档，让我清晰明了的知道了其用法，首先，对布局的应用有了进一步的提升，让我能够熟练运用了网状、流式布局，在添加事件响应的时候，不同的按钮对应不同的监听器，使我有了更加清晰的影响。

先附上GUI界面图：

}

单选按钮（JRadioButton）、复选框（JCheckBox）、组合框（JComboBox）、列表框（JList）、树形目录（JTree）等的结合，让我想到了做一个问卷调查来一起运用这些功能。问卷调查清晰明了的表达出了每个按钮的用法，在以后的运用中，能够更加熟练的进行运用。希望在下次作业中，能够继续加强旧知识的运用，并且结合新知识的运用来一起完成好下一次作业。

最后附上自拍照一张，希望老师能记住我
