Implementing a simple student management system using List in Java

As a JAVA programmer, whether a beginner or an expert, the student management system is a good example. Beginners use arrays, lists, etc. to write simple student management systems, while experts use swing databases. A student management system with an interface. Without further ado, today I will use List to implement the student management system.

The student management system is mainly aimed at students. We first write out the student objects.

package TestProject;public class student {
    String name;
    String age;    public String getName() {        return name;
    }    public void setName(String name) {        this.name = name;
    }    public String getAge() {        return age;
    }    public void setAge(String age) {        this.age = age;
    }
}

Here are some * get and set methods (I just wrote two of them because I was lazy)

    System.out.println("欢迎来到学生管理系统");
    System.out.println("【1】注册");
    System.out.println("【2】查看");
    System.out.println("【3】修改");
    System.out.println("【4】删除");
    System.out.print("请选择您的操作:");

The following is the implementation of each function on the main page. Not much nonsense. Code

package TestProject;import java.util.ArrayList;import java.util.List;import java.util.Scanner;public class Testdemo02 {
    /**
     * 操作界面
     */
    static Scanner sca = new Scanner(System.in);    static List l = new ArrayList();    static student c = new student();    static boolean stu = true;    public static void main(String[] args) {
        System.out.println("欢迎来到学生管理系统");
        System.out.println("【1】注册");
        System.out.println("【2】查看");
        System.out.println("【3】修改");
        System.out.println("【4】删除");
        System.out.print("请选择您的操作:");        while(stu) {
            String stus = sca.nextLine();            switch(stus) {            case "1":
                add();                break;            case "2":
                sel();                break;            case "3":
                set();                break;            case "4":
                del();                break;
            }
        }
    }    /***
     * 添加功能
     */
    static void add() {        while(stu) {
            System.out.println("请输入学生姓名");
            c.setName(sca.nextLine());
            System.out.println("请输入学生年龄");
            c.setAge(sca.nextLine());
            System.out.println("添加成功");
            l.add(c);            break;
        }
    }    /**
     * 查询功能
     */
    static void sel() {        for (student c : l) {
            System.out.println("姓名:"+c.getName()+" "+"年龄:"+c.getAge());
        }
    }    /**
     * 删除功能
     */
    static void del() {
        System.out.println("请输入要删除的姓名");
        String names = sca.nextLine();        for(int i=0;i
Do you think it’s very simple after reading these? It is very suitable for beginners to practice. 
Isn’t it very simple to complete a simple student management system?
