Abstarct class is faster to load, since case for interface JRE expect the methods defined inside to override with the class which implement the interface and that class has to implement all the method defined

Using the interface is simple rather than creating an abstract classes since in the interface user only extends the super class.

HiWhy to compare accessing speed? purpose of interface and abstract class is diferent where interface leaves all the method empty where as abstract classes atleast one method must be incomplete. Well it is functionality not accessing speed to use them.OOPS ! concept

interface is faster than abstract class.Since interface has no method body it is lite weight component.where as in case of abstract class at least one method has method body. defenetly there is a difference.So interface is faster than abstract class.

Interfaces are only faster in accessing because they dont contain any undefined methods whereas abstract classes contain atleast one undefined method.

Interface is slow because it requires extra indirection to find the corresponding method in the actual class. Modern JVMs are discovering ways to reduce this speed penalty.

Abstract Class is relative faster

No, Suppose both have abstract method then ?
