先看一下該項目的功能結構：

1.軟件啟動時，首先進入登錄界面進行注冊和登錄功能。

2.當登陸成功后，進入菜單，首先就可以對開發人員賬戶和密碼進行修改。

3.然后可以對開發人員進行增刪改操作

4.人員添加成功后，根據菜單提示，基于現有的公司成員，組建一個開發團隊以開發一個新的項目。

5.組建過程包括將成員插入到團隊中，或從團隊中刪除某成員，還可以列出團隊中現有成員的列表，開發團隊成員包括架構師、設計師和程序員。

6.團隊組建成功，則可以進入項目模塊，添加項目，分配開發團隊進行開發。

主要涉及以下知識點：

1.類的繼承性和多態性

2.對象的值傳遞、接口

3.static和final修飾符

4.特殊類的使用：包裝類、抽象類、內部類

5.異常處理

6.Java基本語法和流程控制

7.數組，ArrayList集合

該軟件由以下三個模塊組成：

com.team.view 模塊為主控模塊，負責菜單的顯示和處理用戶操作

com.team.service 模塊為實體對象（Employee及其子類如程序員等）的管理模塊， NameListService和TeamService類分別用各自的數組來管理公司員工和開發團隊成員對象

ProjectService是對項目的操作對象類

domain模塊為Employee及其子類等JavaBean類所在的包
