Abstract class in the Java API

[sudipto shekhar]

Hello

I wonder if there are any abstract classes in the Java API ? I have not encountered with one till now but would like to know if there are any.
All your expert comments would help increase my/everyone's knowledge.
Thank you.

Look at Calendar, Graphics, for a start.

There are actually lots of abstract classes in the API. Some of them have names starting with Abstract, some others have names ending in Adapter.
