基于java的作业管理系统代码

很抱歉，由于作业管理系统是一个较为复杂的软件系统，它的代码量较大，无法在这里完整地展示。但我可以为你提供一个基于Java的作业管理系统的主要模块及其代码实现：

1. 学生账号管理模块

public class Student {
    private String name;
    private String password;
    private String email;
    private String phone;

    public Student(String name, String password, String email, String phone) {
        this.name = name;
        this.password = password;
        this.email = email;
        this.phone = phone;
    }

    // getter and setter methods
}

2. 教师账号管理模块

public class Teacher {
    private String name;
    private String password;
    private String email;
    private String phone;

    public Teacher(String name, String password, String email, String phone) {
        this.name = name;
        this.password = password;
        this.email = email;
        this.phone = phone;
    }

    // getter and setter methods
}

3. 作业任务管理模块

public class Assignment {
    private String name;
    private Date deadline;
    private String description;

    public Assignment(String name, Date deadline, String description) {
        this.name = name;
        this.deadline = deadline;
        this.description = description;
    }

    // getter and setter methods
}

4. 作业提交管理模块

public class Submission {
    private Student student;
    private Assignment assignment;
    private Date submissionTime;
    private String filePath;
    private String comment;

    public Submission(Student student, Assignment assignment, Date submissionTime, String filePath, String comment) {
        this.student = student;
        this.assignment = assignment;
        this.submissionTime = submissionTime;
        this.filePath = filePath;
        this.comment = comment;
    }

    // getter and setter methods
}

5. 作业批改管理模块

public class Grading {
    private Teacher teacher;
    private Submission submission;
    private Date gradingTime;
    private int score;
    private String comment;

    public Grading(Teacher teacher, Submission submission, Date gradingTime, int score, String comment) {
        this.teacher = teacher;
        this.submission = submission;
        this.gradingTime = gradingTime;
        this.score = score;
        this.comment = comment;
    }

    // getter and setter methods
}

6. 作业成绩管理模块

public class Grade {
    private Student student;
    private Assignment assignment;
    private int score;
    private String comment;

    public Grade(Student student, Assignment assignment, int score, String comment) {
        this.student = student;
        this.assignment = assignment;
        this.score = score;
        this.comment = comment;
    }

    // getter and setter methods
}

以上是基于Java的作业管理系统的主要模块及其代码实现。当然，这只是一个简单的示例，实际的作业管理系统还需要考虑更多的功能和安全性问题。
