使用Java编写一个学生管理系统，需要包括，添加，排序，查询，修改，删除学生信息的功能

以下是一个简单的学生管理系统的Java代码实现，包括添加、排序、查询、修改和删除学生信息的功能。该程序使用了ArrayList作为学生信息的容器，使用了Scanner类来获取用户的输入。

import java.util.ArrayList;
import java.util.Collections;
import java.util.Scanner;

public class StudentManagementSystem {
    private ArrayList<Student> students = new ArrayList<Student>();
    private Scanner scanner = new Scanner(System.in);

    public void addStudent() {
        System.out.println("请输入学生姓名：");
        String name = scanner.nextLine();
        System.out.println("请输入学生年龄：");
        int age = scanner.nextInt();
        scanner.nextLine();
        System.out.println("请输入学生性别：");
        String gender = scanner.nextLine();
        System.out.println("请输入学生学号：");
        String id = scanner.nextLine();
        Student student = new Student(name, age, gender, id);
        students.add(student);
        System.out.println("学生信息添加成功！");
    }

    public void sortStudents() {
        Collections.sort(students);
        System.out.println("学生信息排序成功！");
    }

    public void queryStudent() {
        System.out.println("请输入要查询的学生学号：");
        String id = scanner.nextLine();
        for (Student student : students) {
            if (student.getId().equals(id)) {
                System.out.println(student);
                return;
            }
        }
        System.out.println("该学生不存在！");
    }

    public void modifyStudent() {
        System.out.println("请输入要修改的学生学号：");
        String id = scanner.nextLine();
        for (Student student : students) {
            if (student.getId().equals(id)) {
                System.out.println("请输入学生姓名：");
                String name = scanner.nextLine();
                System.out.println("请输入学生年龄：");
                int age = scanner.nextInt();
                scanner.nextLine();
                System.out.println("请输入学生性别：");
                String gender = scanner.nextLine();
                student.setName(name);
                student.setAge(age);
                student.setGender(gender);
                System.out.println("学生信息修改成功！");
                return;
            }
        }
        System.out.println("该学生不存在！");
    }

    public void deleteStudent() {
        System.out.println("请输入要删除的学生学号：");
        String id = scanner.nextLine();
        for (Student student : students) {
            if (student.getId().equals(id)) {
                students.remove(student);
                System.out.println("学生信息删除成功！");
                return;
            }
        }
        System.out.println("该学生不存在！");
    }

    public void printMenu() {
        System.out.println("学生管理系统菜单");
        System.out.println("1. 添加学生信息");
        System.out.println("2. 排序学生信息");
        System.out.println("3. 查询学生信息");
        System.out.println("4. 修改学生信息");
        System.out.println("5. 删除学生信息");
        System.out.println("0. 退出程序");
        System.out.println("请选择菜单项：");
    }

    public void run() {
        while (true) {
            printMenu();
            int choice = scanner.nextInt();
            scanner.nextLine();
            switch (choice) {
                case 1:
                    addStudent();
                    break;
                case 2:
                    sortStudents();
                    break;
                case 3:
                    queryStudent();
                    break;
                case 4:
                    modifyStudent();
                    break;
                case 5:
                    deleteStudent();
                    break;
                case 0:
                    System.out.println("程序已退出！");
                    return;
                default:
                    System.out.println("无效的菜单项，请重新选择！");
            }
        }
    }

    public static void main(String[] args) {
        StudentManagementSystem system = new StudentManagementSystem();
        system.run();
    }
}

class Student implements Comparable<Student> {
    private String name;
    private int age;
    private String gender;
    private String id;

    public Student(String name, int age, String gender, String id) {
        this.name = name;
        this.age = age;
        this.gender = gender;
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getGender() {
        return gender;
    }

    public void setGender(String gender) {
        this.gender = gender;
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    @Override
    public int compareTo(Student o) {
        return this.id.compareTo(o.id);
    }

    @Override
    public String toString() {
        return "学生信息：" +
                "姓名='" + name + '\'' +
                ", 年龄=" + age +
                ", 性别='" + gender + '\'' +
                ", 学号='" + id + '\'';
    }
}

在该程序中，Student类表示学生信息，具有姓名、年龄、性别和学号等属性。StudentManagementSystem类表示学生管理系统，具有添加、排序、查询、修改和删除学生信息等功能。该程序使用了ArrayList来存储学生信息，使用了Collections类的sort方法来对学生信息进行排序，使用了Scanner类来获取用户的输入。
