用java实现简单的教室管理系统

好的，教室管理系统可以包括以下功能：

1. 学生管理：添加、删除、修改学生信息
2. 教师管理：添加、删除、修改教师信息
3. 课程管理：添加、删除、修改课程信息
4. 教室管理：添加、删除、修改教室信息
5. 课表管理：排课、修改课表信息
6. 成绩管理：录入学生成绩、查询学生成绩

下面是一个简单的教室管理系统的Java代码：

import java.util.List;
import java.util.Scanner;

public class ClassroomManagementSystem {
    private List<Student> students;

    }

// 类似于 Student 类，定义 Teacher、Course、Classroom、Schedule 和 Score 类

这只是一个简单的示例，实际的教室管理系统可能需要更多的功能和更复杂的实现。
