哪位大哥哥可以给我关于jdbc的源程序？

package com.db.dbHelp;

import java.sql.*;

public class DBAccess {
String sDBDriver = "oracle.jdbc.driver.OracleDriver";
String url = "jdbc:oracle:thin:@localhost:1521:xdf";
String sHint = "";
ResultSet rs = null;
Connection conn = null;
Statement stmt = null;
String user = "scott";
String pwd = "tiger";

public String getSHint(){
return sHint;
}

public void setSDBDriver(String dbDriver){
sDBDriver = dbDriver;
}

public String getSDBDriver(){
return sDBDriver;
}

public String getUrl(){
return url;
}

public void setUrl(String s){
url = s;
}

public ResultSet getResultSet(){
return rs;
}

//初始化
public boolean initialize(String dbDrive,String dbConn,String user,String pwd){
