怎么用Java写 ：一个班级包含一些学生，每个学生有固定的学号与姓名，有JAVA，计算机网络，英语三门课的成绩。试采用面向对象程序设计方法，实现如下功能：
分别找出班上总成绩及单科成绩最高的学生（若有多个，应都找出来），并输出这些学生的信息；分别找出班上至少有一门课成绩低于60分、至少有两门课成绩低于60及三门课成绩均低于60分的学生，并输出这些学生的信息。允许通过输入一个学生的学号或姓名（姓名可能重复，因此可能找到多个学生）寻找学生，并输出其信息（或找到多个，则都输出）。

上述代码中，Student类表示一个学生，包含学号、姓名和三门课的成绩。main方法中创建了一个学生列表，然后分别找出班上总成绩及单科成绩最高的学
