关于java使用extends List<>的ArrayList<>存数据库中的数据

今天老师讲了ArrayList<>所以，利用这点时间做个记录吧。希望对于初学者有些帮助。

导入测试类：

package com.sqldemo.Test;

import java.util.Scanner;

import com.sqldemo.StudentDao;
import Entity.Student;
public class TestDemo {
    
    public static void main(String[] args) {
        Student stu = new Student();
        System.out.println("--------本程序执行数据入库操作---------");
        Scanner sc = new Scanner(System.in);
        System.out.print("学生姓名：");
        String stuName = sc.nextLine();
        stu.setName(stuName);
        System.out.print("学生性别:");
        String stuSex = sc.nextLine();
        stu.setSex(stuSex);
        System.out.print("学生年龄:");
        int stuAge= sc.nextInt();
        stu.setAge(stuAge);
        sc.close();
        new StudentDao().AddStudent(stu);    
    }
}

导出测试类：

package com.sqldemo.Test;


import java.util.List;

import Entity.Student;

import com.sqldemo.studentAcquire;

public class AcquireTestDemo {

    public static void main(String[] args) {
        
        List<Student> students = new studentAcquire().getStudent();
        System.out.println("| ID | Name | sex | age|");
        for(Student stu:students){
            System.out.print("|  ");
            System.out.print(stu.getId());
            System.out.print("|  ");
            System.out.print(stu.getName());
            System.out.print("|  ");
            System.out.print(stu.getSex());
            System.out.print("|  ");
            System.out.print(stu.getAge());
            System.out.println("|");
        }
        System.out.println("打印完毕");
    }
}
