Answer Posted / aruna raman
Actually abstract are faster than interfaces classes.
interfaces are Slow, requires extra indirection to find the
corresponding method in the actual class. Modern JVM's are
discovering ways to reduce this speed penalty.
Abstract Class ::
- It cannot defines all the methods
- It has subclass.
- Here, Subclass is useless
- A class can be extend an abstract class
Interface ::
- It defines all the methods
- It must have implementations by other classes, But there
will be no use of that.
- Only an interface can extend another interface.
