It is provided in the jdbc jar provided by different vendors oracle, db2 etc.
If you have the software, you can open the jar and see the implementation for them.

Yes. As Jeevan said, the implementation is provided by the jdbc driver jar.

DriverManager provides a reference to the class, not the implementing class.
 
Yes, of course, and I accept that blame. In fact, i covet that blame. As does this tiny ad:
