[mohan paladi]

hi friends,
I would like to know the exact difference between
an ABSTRACT class and an INTERFACE.
Which would suit the exact requirement.
thanks in advance

Hi,
interface is to help java programmers to implement multiple
inheritance.Your class has to implement an interface or
multiple interfaces.Similarly one interface can extends other interface as well

whereas "abstract"class can not be instantiated.
Hope this helps.

Hello Mohan,
I would like to add more difference,
-In interface, the methods will not be having any 'body'(definition) but in abstract classes methods r allowed to have body.
- In interface if u define any variables then it will be implicitly coderanch, as well methods also. But not so in abstract classes.
