There are few differences with abstract class and interface. One obvious difference is that abstract class can implement methods it means abstract class can declare whole method body. On the other hand interfaces only declare method signature, they don�t implement method itself.

Also, you implement interface and extend abstract class. It means you have to implement all the declared methods from interface. Whereas in case of abstract class, you need to implement only abstract methods.
