Hi All,

I want to know where we have to use abstract class and where we have to use the Interface.

If you want to provide some/common implementations for certain behaviors you may use abstract classes whereas interfaces (being 100% abstract) you force the implemented class to implement the behavior. You may find lots of information by searching through the forums (java) here. And find this Sun tutorial which would be helpful.
