JAVA swing界面实现数据库增删改查

1、数据库程序设计大作业班级：2012级软件外包服务一班学号：201215140117姓名： 。时间：2013-6-19 1功能描述1.1 功能简介用swing做出图形化界面形式，实现数据库的增删改查把员工表跟部门表连接起来，实现数据的增加，删除，修改，查找。1.2 实现步骤（1）安装好虚拟机，并在其下确认oracle已安装成功（可以在dos下输入相关命令来检查是否安装成功）。（2）在网络中心修改pc机上的VMware Network Adapter的IP、子网页码（默认）、网关。（3）修改虚拟机的IP、网掩码（默认）、网关，确保PC机上的网关和虚拟机的IP一致。（在控制面板>网络和共享中心

2、>本地连接3>属性中，修改IP、网掩码）（4）在PC机的dos命令控制台ping虚拟机的IP，确保正常，能ping通（即将虚拟机内外ping通）。（5）配置好虚拟机下的oracle的数据库和监听。（6）在eclipse中编写相关代码，并用jtable实现图形化界面，用以实现与数据库的连接和操作数据库等功能。（7）在eclipse中导入数据库的驱动。（8）运行eclipse，查看运行结果。2. 核心代码2.11. 数据库连接public class DatabaseConnection public static void main(String args Connection co
