Answer 1

网上有现成的代码，找一找就有了，可以参考下

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

public class StudentManagementSystem {
private ArrayList<Student> studentList;

public StudentManagementSystem() {
    studentList = new ArrayList<>();
}

public void showMenu() {
    System.out.println("========== 学生信息管理系统 ==========");
    System.out.println("1. 学生信息录入");
    System.out.println("2. 学生信息浏览");
    System.out.println("3. 学生信息查询");
    System.out.println("4. 学生信息删除");
    System.out.println("5. 学生信息修改");
    System.out.println("0. 退出系统");
    System.out.println("=====================================");
}
