How many ways can we extend a class ?

Can i say that we can extend a class in two ways :
1. using extends
2. using anonymous inner class

You can extend an exception class as the same way as you extend any other class.
An anonymous inner class implicitly extends another class - so it can be used.

@ jose

yes ofcourse you can extend a class using extends ...

anonymous innner classes serve as an implicit datatype for the class they are constructed in ... having access to all its (data/method) members.
