java.sql.Connection is a standard JDK class. You cannot change that.

It's an Interface not a class.

While it is true that it is an interface, it is common practice to call both as class when the difference is irrelevant for the point in discussion. After all, there is a "class" file with extension .class, not .interface

Even so, it has been updated to make it clear.

thank you for your feedback!
