用Java设计程序(内部类，匿名类)

Question

1、三大体育媒体互联网平台,由于资源独占,有些类别的运动只能在某个平台上进行独播

2、足球赛事只能在平台A上进行独播,篮球赛事只能在平台B上进行独播,排球赛事只能在平台C上进行独播,其他赛事可以在几个平台上进行直播;

3、要求

( 1)三个体育直播平台EA、EB、EC设计为三个类

( 2)设计一个体育赛事的类SportsGame

(3)三个赛事设计为体育赛事的三个子类,分别作为三个平台的内部

(3)其他羽毛球、乒乓球等赛事设计为普通的类,继承自体育賽事( 4)可以根据不同赛事的特点,为其设计内部的成员变量和成员函数(5)利用匿名类新增其他的体育赛事

( 6)在main函数中进行测试

( 7)增加比赛规则接口IRule, 令所有的体育赛事实现该接口,重新制定各自的比赛规则
