Java连载141-编辑实体类

一、安装mysql

• 首先在windows上安装mysql,地址：https://mirrors.huaweicloud.com/mysql/Downloads/MySQL-8.0/,找到最新版mysql-8.0.21-winx64.zip，点击下载

• 解压到某一个目录，然后设置环境变量，并生成data文件
  

• 后续操作请参考https://www.cnblogs.com/yunlongaimeng/p/12558638.html
  

坑区：一定要使用管理打开的方式打开cmd再进行命令行操作，否则就会报错

• 输入mysql -u root -p，进入之后首次启用无密码，直接回车即可，执行create database ibank创建数据库
  

二、实体类创建

• 该实体类就是用对必须存储的信息和相关行为进行建模。
