How to design a simple student course selection and classroom adjustment system in Java?

Introduction

With the improvement of education level and the increasing abundance of educational resources, student course selection has become an indispensable part of college life. However, there are some problems in student course selection, such as classroom capacity limitations and student course selection conflicts. In order to solve these problems, we can use Java language to design a simple student course selection classroom adjustment system.

System Design

The system is mainly composed of three categories: students, teachers and classrooms.

Student class

The student class (Student) contains attributes such as the student's name, student number, and selected course information. Students can select and withdraw from courses through methods.

public class Student {
    private String name;
    private int studentId;
    private List<Course> courses;
    
    // constructors, getters, setters, etc.
    
    public void selectCourse(Course course) {
        // 选课逻辑
    }
    
    public void dropCourse(Course course) {
        // 退课逻辑
    }
}

Teacher class

The teacher class (Teacher) contains attributes such as the teacher’s name, job number, and course information. Teachers can create, modify, and delete courses through methods.

public class Teacher {
    private String name;
    private int teacherId;
    private List<Course> courses;
    
    // constructors, getters, setters, etc.
    
    public void createCourse(String courseName, int capacity) {
        // 创建课程逻辑
    }
    
    public void modifyCourse(Course course, int newCapacity) {
        // 修改课程容量逻辑
    }
    
    public void deleteCourse(Course course) {
        // 删除课程逻辑
    }
}

Classroom class

The classroom class (Classroom) contains attributes such as the number and capacity of the classroom. Classrooms can query the current course schedule and adjust course schedules through methods.

public class Classroom {
    private String classroomId;
    private int capacity;
    private List<Course> courses;
    
    // constructors, getters, setters, etc.
    
    public List<Course> getCurrentCourses() {
        // 查询当前课程安排逻辑
    }
    
    public void adjustCourse(Course course, Classroom newClassroom) {
        // 调整课程安排逻辑
    }
}

Course Class

Course class (Course) contains attributes such as the name, capacity, and teacher information of the course.

public class Course {
    private String courseName;
    private int capacity;
    private Teacher teacher;
    
    // constructors, getters, setters, etc.
}

System Process

1. Students use their student ID and password to log in to the system.
2. Students choose courses of interest.
3. The system creates courses through the createCourse method of the teacher class.
4. Teachers can modify the course capacity through the modifyCourse method.
5. Teachers use the adjustCourse method of the classroom class to adjust the course schedule.
6. Students can withdraw from courses through the dropCourse method.
7. Teachers use the getCurrentCourses method of the classroom class to query the current course schedule.

Summary

Designing a simple student course selection classroom adjustment system through Java language can effectively solve problems such as student course selection conflicts and classroom capacity limitations. The design idea of ​​the system is to realize the functions of course selection and classroom adjustment through the interaction of students, teachers and classrooms. Through reasonable system processes, students and teachers can easily select courses and adjust course schedules. This simple system can provide a better user experience for students during the course selection process.
