Difference between abstract class and interface

Answer Posted / aloka

INTERFACE:
1)a class can implement any number of interfaces.
2)variables declared in interfaces are by default final
3)members on interfaces are public by default
4)should be implemented using keyword "implements"
5)absolutely abstract and cannot be instantiated.
6)requires more time to find the actual method in the
corresponding class
7) if we add a new method to an interface, then we have to
track down all implementations of interface and define
implementation of the new method.
ABSTRACT CLASS:
1)a class can inherit only one abstract class
2)may contain non-final variables
3)members can be declared with any access specifier
4)should be inherited using "extends" keyword
5)cannot be instantiated but can be invoked if main() exists
6)faster than interfaces
7)if we add a new method to abstract class, then we've the
option of providing default implementation and therefore all
existing code might work properly.
