swing界面实现数据库增删改查

1、数据库程序设计大作业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>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

2、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package .dbc;import java.sql.Connection;import java.sql.DriverManager;import java.sql.ResultSet;import java.sql.SQLExc

3、eption;import java.sql.Statement;public class DatabaseConnection public static void main(String args) Connection conn = null;Statement stmt = null;ResultSet rs = null;try Class.forName("oracle.jdbc.driver.OracleDriver");String url = "jdbc:oracle:thin:28:1521/WFJ"conn =

4、 DriverManager.getConnection(url, "hr", "hr");stmt = conn.createStatement();String sql = "select * from departments"rs = stmt.executeQuery(sql);while (rs.next() System.out.print(rs.getInt("department_id");System.out.print("t");System.out.print(rs.get

5、String("department_name");System.out.print("t");System.out.print(rs.getInt("manager_id");System.out.print("t");System.out.print(rs.getInt("location_id");System.out.println(); catch (ClassNotFoundException e) e.printStackTrace(); catch (SQLException e

6、) e.printStackTrace(); finally try if (rs != null) rs.close();if (stmt != null) stmt.close();if (conn != null) conn.close(); catch (SQLException e) / TODO Auto-generated catch blocke.printStackTrace();2. 生成get set方法package edu;public class Country private String department_id; private String departm

7、ent_name; private String area; private String population; public String getdepartment_id() return department_id; public void setdepartment_id(String department_name) = department_id; public String getdepartment_name() return department_name; public void setdepartment_name(String department
