Hi sir , what should I put on user and password in the connection part ?

It's really helpful to me sir. The tutorial is comprehensible and simple. Thank you for this. Keep up.
I think we don't need to download Connector/J since it's already included in the MySQL Workbench installation. Am I right?
How do you automatically insert ID? I made the same app and have to do thing like this:
String sql = "insert into shop" + "(Name, Adress, Phone, ID_Shop)" + "values('xxx', 'xxx', '111111111', '6')";
Something like this doesn't work:
String sql = "insert into shop" + "(Name, Adress, Phone)" + "values('xxx', 'xxx', '111111111')";
I guess it's about default value of ID. But how and where can I set it?
Anyway, thanks for your lessons, they are great and very useful 🙂
