代碼：

package com.sp;

import java.sql.*;

//演示JDBC連接

public class OraDemo2 {

public static void main(String[] args) throws ReflectiveOperationException, SQLException {

// TODO Auto-generated method stub

//1.加載驅動

Class.forName("Oralce.jdbc.driver.OracleDriver");

//2.得到連接

Connection ct = DriverManager.getConnection("jdbc:oracle:thin:@192.168.1.103:1158:ORCL","scott","330328");

Statement sm = ct.createStatement();

ResultSet rs = sm.executeQuery("select * from emp");

while(rs.next()){

System.out.println("用戶名："+rs.getString(2));

}

}

}
