Answer / sandeep pokala
Interface is a set of abstract methods,all the methods have
to be overridden by the class which ever implements the
interface.
Abstract class is collection of data and methods,which are
abstract. In abstact class some methods may contain
defination,but in interface every method should be abstract
( no definations in the methods)

Answer / hemalatha ivvala
Abstrat Class: It is a combination of Concrete Methods and
Abstract Methods.
Interface: Which class is only having abstract methods is
called interface.
Concrete Methods: Methods having declaration and definition
Abstrat Method: Methods having only declaration not having
any definition. Becuase abstract methods are used to provide
data abstractions(Means providing method definition and
hiding method declaration to provide security to the client).
