在dos命令中是可以进入MySQL的 database 有了table 也有了
JDBC:D:/Study/MySQL/mysql-connector-java-5.1.7-bin.jar 也有了
可是......
为什么就是出现错误呢，新手上路。
求各位帮帮忙啊！！！

Answer 1

connection=DriverManager.getConnection("jdbc:mysql://localhost:3306/stone,'root','371169479'"); //一般是这样写
String url = "jdbc:myql://localhost:3306/stone";   
String user = "root";   
String password = "371169479"; 
Connection conn =DriverManager.getConnection(url,user,password);
