hi
well though basic working is the same but there are many difference.Major one being-

1-Abstract classes are extended and interfaces are implemented.That means you can extend only one abstract class at a time but you can implement any number of interfaces.

2-Abstract class have both abstract and normal methods where as interfaces have all their methods abstract.

There are numerous other differences.Search google and you can find more.
