Java連載141-編輯實體類

1、安裝mysql

• 首先在windows上安裝mysql,地址：https://mirrors.huaweicloud.com/mysql/Downloads/MySQL-8.0/,找到最新版mysql-8.0.21-winx64.zip，點擊下載

• 解壓到某一個目錄，而後設置環境變量，並生成data文件
  

• 後續操做請參考http://www.javashuo.com/article/p-rbkycqyp-ne.html
  

坑區：必定要使用管理打開的方式打開cmd再進行命令行操做，不然就會報錯

• 輸入mysql -u root -p，進入以後首次啓用無密碼，直接回車便可，執行create database ibank建立數據庫
  

2、實體類建立

• 該實體類就是用對必須存儲的信息和相關行爲進行建模。
