JavaSwing+derby通讯录
此通讯录为sun公司在2006年公布，它的优点有：
分层结构如上图
1.AddressFrame为主窗体它里面装入三个窗体AddressListPanel-AddressActionPanel-AddressPanel
2.AddressListPanel负责装入列表内容；AddressActionPanel负责按钮监听；AddressPanel负责编辑
3.AddressFrame负责连接数据库AddressDao
4.AddressDao又使用了Configuration.properties外部配置文件
总结：一：思路非常之清晰，就像一位朋友所说，拍《盗梦空间》的那位仁兄导演应该是学过编程的。
二：此系统看似很小，里面五脏俱全，如果每个语句与方法一句一句的分析与参透，将会受益非浅！
完整源码请在此下载：http://download.****.net/detail/youyigong/3779854 同时我将此打包，可以独立运行
