when to use abstract class and when to use interface?

Answer Posted / rod

The above answer is wrong because it uses the word
"interface" to define itself. You simply cannot say "which
are available in the interface go for interface" because you
cannot use a word in the description of itself. It is like
saying a what is a ball...well a ball is a ball. Which is
correct but does not answer the question.
Whoever wrote the above answer does not speak english as a
first language and therefore they are confusing the issue.
