这个适用于初学者,JDBC连接MYSQL,这些是JDBC一些测试程序

package jdbc;
import java.sql.*;
public class L1{

			Class.forName(driverName);

			String url=
				"jdbc:oracle:thin:@192.168.2.125:1521:stu";
			String username="openlab";
			String pwd="open123";

			System.out.println("con->"+con);
		}catch(Exception e){
			e.printStackTrace();
		}finally{
