Java Question Of Interfaces

0 Developer John · February 26, 2015
I haven't reached the difference between implementing or extending, but how can a class get information from an interface? What are the rules for what a class can implement or extend? Would about an interface itself?

I know that interfaces can only extend other interfaces, but would about implementation?

Classes implement interfaces. Classes extend classes, be it abstract or not. To be honest, that's about all I know about the difference between the two either ;).
