一个基本的Java学生选课系统需要以下几个类:
1. 学生类(Student):包含学生的基本信息,如学号、姓名、性别等,以及已选课程列表。
2. 课程类(Course):包含课程的基本信息,如课程编号、课程名称、授课教师、授课地点等。
3. 教师类(Teacher):包含教师的基本信息,如工号、姓名、性别等,以及所授课程列表。
4. 选课系统类(CourseSelectionSystem):包含所有操作方法,如添加学生、添加课程、添加教师、学生选课、查看选课情况等。
下面是一个简单的Java学生选课系统的代码实现:
```
public class Student {
private String id;
private String name;
private String gender;
private List<Course> courseList;
public Student(String id, String name, String gender) {
this.id = id;
this.name = name;
this.gender = gender;
courseList = new ArrayList<>();
}
public void addCourse(Course course) {
courseList.add(course);
}
public void dropCourse(Course course) {
courseList.remove(course);
}
}
public class Course {
private String id;
private String name;
private Teacher teacher;
private String location;
public Course(String id, String name, Teacher teacher, String location) {
this.id = id;
this.name = name;
this.teacher = teacher;
this.location = location;
}
public String getId() {
return id;
}
public String getName() {
return name;
}
public Teacher getTeacher() {
return teacher;
}
public String getLocation() {
return location;
}
}
public class Teacher {
private String id;
private String name;
private String gender;
private List<Course> courseList;
public Teacher(String id, String name, String gender) {
this.id = id;
this.name = name;
this.gender = gender;
courseList = new ArrayList<>();
}
public void addCourse(Course course) {
courseList.add(course);
}
}
public class CourseSelectionSystem {
private List<Student> studentList;
private List<Teacher> teacherList;
private List<Course> courseList;
public CourseSelectionSystem() {
studentList = new ArrayList<>();
teacherList = new ArrayList<>();
courseList = new ArrayList<>();
}
public void addStudent(Student student) {
studentList.add(student);
}
public void addTeacher(Teacher teacher) {
teacherList.add(teacher);
}
public void addCourse(Course course) {
courseList.add(course);
}
public void enroll(Student student, Course course) {
student.addCourse(course);
course.getTeacher().addCourse(course);
}
public void drop(Student student, Course course) {
student.dropCourse(course);
course.getTeacher().getCourseList().remove(course);
}
public List<Student> getStudentList() {
return studentList;
}
public List<Teacher> getTeacherList() {
return teacherList;
}
public List<Course> getCourseList() {
return courseList;
}
}
```
这个学生选课系统只是一个基础框架,可以根据需求进行扩展。例如,可以添加管理员类,实现对学生、课程和教师的添加、修改和删除操作;可以添加成绩类,记录学生的课程成绩等。
