一、题目
个人(Person)与团队(Team)可以形成一个组织(Organization):组织有两种:个人组织和团队组织,多个个人可以组合成一个团队,不同的个人与团队可以组合成一个更大的团队。
使用控制台或者JavaFx界面完成以下功能:维护团队,并递归显示团队的所以成员。
控制台客户端功能提示:简化起见,采用自顶向下的方式创建团队,例如,创建“t1”团队,然后创建“t1”的子团队“t1.1”团队、“t1.2”团队,创建“t1.1”的子团队“t1.1.1”,子团队“t1.1.1”由“p1”、“p2”和“p3”三个人。创建完成后,递归输出这些对象;例如,当前情况下输出这样的消息:
团队t1有t1.1, t1.2, t1.3三个子对象;团队t1.1有t1.1.1一个子对象;团队t1.1.1有p1, p2, p3三个子对象。
在此基础上修改一个对象,例如,把p3对象从子团队“t1.1.1”中删除,然后添加到t1.1团队中;完成这些操作后,递归输出这些对象,结果应该是
团队t1有t1.1, t1.2, t1.3三个子对象;团队t1.1有p3, t1.1.1两个子对象;团队t1.1.1有p1, p2两个子对象。
JavaFx界面提示:JavaFx的基本界面如下,同学们在此基础上适当修改.
左边是创建对象的树状结构展示,右边是选中某一个节点后的操作。例如,如果选中T12。然后就可以输入T121,输入后直接刷新树状结构。
