java学生信息管理系统截图

很抱歉，我无法提供截图。但是我可以为您提供一个简单的Java学生信息管理系统的示例代码，供您参考：

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

class Student {
    private String sid;
    private String name;
    private int age;
    private String address;

    public Student(String sid, String name, int age, String address) {
        this.sid = sid;
        this.name = name;
        this.age = age;
        this.address = address;
    }

    public String getSid() {
        return sid;
    }

    public String getName() {
        return name;
    }

    public int getAge() {
        return age;
    }

    public String getAddress() {
        return address;
    }
}

public class StudentManagementSystem {
    public static void main(String[] args) {
        ArrayList<Student> studentList = new ArrayList<>();
        Scanner sc = new Scanner(System.in);

        while (true) {
            System.out.println("请选择操作：");
            System.out.println("1. 添加学生信息");
            System.out.println("2. 修改学生信息");
            System.out.println("3. 删除学生信息");            System.out.println("4. 查看所有学生");
            System.out.println("0. 退出系统");

            int choice = sc.nextInt();
            sc.nextLine();

            switch (choice) {
                case 1:
                    addStudent(studentList);
                    break;
                case 2:

                    break;
                default:
