java 简单 学生管理系统
这应该算是一个简单学生管理系统吧。由于没有听课，刚开始凭群文件作业要求写了一个，后来发现有点过于简单，于是小小的扩展了一下。先展示一下程序界面。
第一次手生，代码不太好看，但是有点累，也不想再改了。
可以从文件导入或导出 。文件格式是XML，如图
支持筛选操作，但是不支持模糊搜索，模糊搜索部分不想再做了，感觉很累，就先这么着吧，
选中列表某一行会及那个信息自动填充到上面的框里面，但是目前我还没有支持直接在单元格内编辑保存，不过，监听什么的我全部写好了，只要稍加十几行代码就可以实现，同样也不想再写了，虽然区区十几行代码，还是不想动手。以后随缘再说。
筛选条件选成性别女
加上姓名筛选
只有id为主键，id是唯一的，其他字段都允许重复
单元格最后一行，点击会提示是否删除改行。
这一部分代码我写的累赘了，但是，为了学有所用，用另一种方法实现，而不是在原有方法里面加条件来实现是个很好的事情，所以我没有精简代码
其他筛选条件类似
下面是代码
主类，本来是写成三个类的，student类，start类，data类，后来我觉得太长，就把他们都分开了，花了些时间，走了些弯路，现在的代码也是有点累赘，同样的 不想改了，。
写成好几个类的一大坏处就是粘贴代码都很累。
