How to implement a simple student homework submission deadline reminder system in Java?

With the development and popularization of education, students need to submit various assignments to teachers. In order to better manage student homework and remind students to submit homework on time, we can use the Java programming language to implement a simple student homework submission deadline reminder system.

First, we need to design a student class and homework class.

public class Student {
    private String name;
    private String ID;
    
    public Student(String name, String ID) {
        this.name = name;
        this.ID = ID;
    }
    
    // getter and setter methods
    
    // 提醒学生提交作业的方法
    public void remindToSubmitAssignment(Assignment assignment) {
        System.out.println("Dear " + name + ", please submit your assignment before " + assignment.getDeadline() + ".");
    }
}

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

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

    // getter and setter methods
    
    public String getDeadline() {
        return deadline;
    }
}

In the main method, we can create student objects and homework objects, and call the student's reminder method to remind students to submit their homework on time.

public class Main {
    public static void main(String[] args) {
        Student student = new Student("张三", "123456");
        Assignment assignment = new Assignment("数学作业", "2021年10月10日 23:59");
        
        student.remindToSubmitAssignment(assignment);
    }
}

The above code will output: "Dear Zhang San, please submit your assignment before October 10, 2021 23:59.", reminding students to submit their assignments on time.

Of course, this is just a simple example. In actual projects, we may need more complex functions, such as storing information about multiple students and assignments, and we can use databases or files to achieve data persistence. Also consider using cron tasks to regularly check when assignments are due and send reminders to students.

To summarize, by using the Java programming language, we can easily implement a simple student homework submission deadline reminder system. This system can remind students to submit homework on time and improve students' consciousness and time management skills.
