通讯录管理系统设计用JAVA实现以下代码 1)录入成员信息。基本信息:姓名、现就读大学名称及班级名、专业、家庭住址、家庭联系电话、邮编、本人联系电话等。2)删除一个成员信息。3)修改成员信息并保存 4)能够按姓名对成员信息进行检索并将检索结果显示在屏幕上。 5)能够按专业对成员信息进行检索并将检索结果显示在屏幕上。6)显示所有成员信息。 7)要求利用菜单的形式进行管理。

好的，以下是通讯录管理系统的JAVA代码，包含了您提到的所有功能：

您可以将以上代码保存为一个名为 `AddressBookManagementSystem.java` 的文件，然后在命令行中使用 `javac AddressBookManagementSystem.java` 命令编译它，再使用 `java AddressBookManagementSystem` 命令运行它。

希望这个代码可以帮助到您！
