Answer / dhanya
Any class with one or more abstract method is called an abstract class.It can have data attributes,concrete methods and constructors.Abstract class can differ the implementation
by declaring the method to be abstract,and a Java interface declares only the contract and no implementation.All methods declared in interface are public and abstract.All attributes are public,static and final.
