well;Abstract class must be extended/subclassed to be useful. It serves as a template. A class that is abstract may not be instantiated ie, you may not call its constructor, abstract class may contain static data. Any class with an abstract method is automatically abstract itself, and must be declared as such.A class may be declared abstract even if it has no abstract methods. This prevents

Hi SunilAn abstract method is a method which has no implementation, means an abstract method is deliberately missing its method body.An abstract method is a method that is declared without an implementation without braces, and followed by a semicolon, like this: abstract void moveTodouble deltaX, double deltaY;If a class includes abstract methods, the class itself must be declared abstract, as in

An abstract method is a dummy code method which has no implementation. It is often used as a placeholder to be overridden later by a subclass of or an object prototyped from the one that implements the abstract method. In this way, abstract methods help to partially specify a framework....well, A class that cannot be instantiated. A concept in C known as pure virtual method. A class that must be inherited

Choosing interfaces and abstract classes is not an either/or proposition. If you need to change your design, make it an interface. However, you may have abstract classes that provide some default behavior. Abstract classes are excellent candidates inside of application frameworks.Abstract classes let you define some behaviors; they force your subclasses to provide others. For example, if you have

An abstract class can have instance methods that implement a default behavior. An Interface can only declare constants and instance methods, but cannot implement default behavior and all methods are implicitly abstract. An interface has all public members and no implementation. An abstract class is a class which may have the usual flavors of class members private, protected, etc., but has some abstract

Hi FriendThe difference and similarities b/w the abstract and interface Interface contains methods that must be abstract; abstract class may contain concrete methods. interface contains variables that must be static and final; abstract class may contain non-final and final variables. members in an interface are public by default, abstract class may contain non-public members. interface is used

A class that contains the common features of components of several classes, but cannot it be instantiated by itself. It represents an abstract concept for which there is no actual concrete expression....In object-oriented programming, a class designed only as a parent from which sub-classes may be derived, but which is not itself suitable for instantiation. Often used to "abstract out" incomplete

Abstract class is a class that serves only as a base class from which classes are derived. No objects of an abstract base class are created. A base class that contains pure virtual functions in an abstract base class.Interface is the visible methods of an object....hi lucky the differences are Abstract classes Abstract classes are used only when there is a is-a type of relationship between the classes

hi,friendAbstraction in C ProgrammingIntroductionAbstract ion is a central concept in computer science. Object-oriented programming supports abstractions to a higher degree that almost all other programming paradigms. Classes model abstractions in object-oriented programming.Classes represent abstractions in object-oriented programs and are the central focus of the analysis and design done before any

Well Neha,Data abstraction is the enforcement of a clear separation between the abstract properties of a data type and the concrete details of its implementation. The abstract properties are those efficiency improvements over time. The idea is that such changes are not supposed to have any impact on client code, since they involve no difference in the abstract behaviour.For example, one could define

well,Abstraction is the process or result of generalization by reducing the information content of a concept or an observable phenomenon, typically in order to retain only information which is relevant for a particular purpose. For example, abstracting a leather soccer ball to a ball retains only the information on general ball attributes and behaviour. Similarly, abstracting happiness

abstract class - a class that serves only as a base class from which classes are derived. no objects of an abstract base class are created. a base class that contains pure virtual functions is an abstract base class....Abstract classes are classes that contain one or more abstract methods.

well, Abstraction from the Latin abs, meaning away from and trahere, meaning to draw is the process of taking away or removing characteristics from something in order to reduce it to a set of essential characteristics. In object-oriented programming, abstraction is one of three central principles along with encapsulation and inheritance. Through the process of abstraction, a programmer hides all
