先通过ScoreInformation来建立类来帮助存储记录信息。

1解题思路显示用一个单独的类来帮忙记录一下信息
2在ScoreManagement中使用几个类似于全局变量的ScoreInformation数组来计入学生的 信息，和用scanner全局null来减少次数，用judge的String类型帮忙记录Y和N。
3使用多个菜单来来刷屏帮助实现界面。
4在录入和 修改和绩点分别单独写了函数主要是用switch来分别使用不同选项来实现不同功能还用switch来实现Y/N的功能。
5算绩点就是通过两个普通函数来实现功能，是否符合毕业绩点直接使用if语句。

成绩录入
2、成绩修改
3、成绩绩点
4、退出
