}刚学java没多久，求大神指导~~

Answer 1

就是infoPanel和changeKeyPanel之间切换
这个没有实现

Answer 2

你的代码没贴完整
还有borrower类没有
运行不起来
把所有类贴完整

Answer 3

代码太多，不好写，你就不要管borrower类，随便写点数据就可以啦，另外在吧这个BorrowerIofoPanel添加到JFrame中就可以运行啦

Answer 4

用弹出一个JDialog或者Tab布局管理器都可以啊

Answer 6

ChangeKeyPanel
还没实现ActionListener 的方法。

Answer 7

1.点击跟改密码，让原窗口隐藏，让新窗口显示setVisible（）
2.extends JFrame
3.直接用JDialog 就好啦
