javaswing界面实现数据库增删改查

-.z.数据库程序设计大作业班级：2012级软件外包效劳一班**：7：。。。 时间：2013-6-191．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VMwareNetworkAdapter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——>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.核心代码数据库连接packageorg.l*.dbc;importjava.sql.Connection;importjava.sql.DriverManager;importjava.sql.ResultSet;importjava.sql.SQLE*ception;importjava.sql.Statement;publicclassDatabaseConnection{ publicstaticvoidmain(String[]args){ Connectionconn=null;
