msdbdemo.java

通过java连接数据库 并通过 测试 数据库名称message 表格为 person:

package dataBase;
import java.sql.*;
import java.util.ArrayList;

	final static String password = "";
	Connection conn=null;
 	MSDBdemo(){
		try{
			
			Class.forName(DB_DRIVER).newInstance();
			System.out.println("数据库驱动程序注册成功！");
			conn=DriverManager.getConnection(url, user, password);
			
			System.out.println("数据库连接成功");
			
		}
		catch(Exception e){
			
			e.printStackTrace();
			System.out.println("数据库连接失败");
			
		}
	}
	Connection getconn(){

	}
	public static void main(String[] args){
