Introduction to Web services technologies Web Services Introduction Before understanding why web services are popular or so important, you should first assess ‘What is Web Services, what’s its use and how does it work?’ The nature and functionality of web services have made it very popular. Nowadays, our business systems have matured, transparent and more logical and high tech, and all for these are because of web services. Definition Web services are the amalgamation of eXtensible Markup Language (XML) and HyperText Transfer Protocol HTTP that can convert your application into a Web-application, which publish its function or message to the rest of the world. In other words, we can say, web services are just Internet Application Programming Interfaces (API) that can be accessed over a network, such as Internet and intranet, and executed on a remote system hosting the requested services. Web-applications are simple applications that run on the web. Web services are b...

Polymorphism in Object oriented Programming
Polymorphism in Object oriented Programming The definition of Polymorphism as per the dictionary is 'The occurrence of something in different forms,in particular' . As per biology, the polymorphism is nothing but exhibiting different forms by a species. Poly means many . The same principle is applicable in Object oriented programming where the Objects at runtime decide what behavior will be invoked. Polymorphism is implemented in Java using method overloading and method overriding concepts. Polymorphism with example: Let us Consider Car example for discussing the polymorphism . Take any brand like Ford, Honda, Toyota, BMW, Benz etc., Everything is of type Car. But each have their own advanced features and more advanced technology involved in their move behavior. Now let us create a basic type Car Car.java public class Car { ...
Encapsulation in Object Oriented Programming
Encapsulation in Object Oriented Programming Encapsulation is one of the four fundamentals of the Object oriented programming. What is Encapsulation? Encapsulation is a language mechanism to restrict the access of the Objects components to other Objects or Classes. Encapsulation helps in enforcing the security of the data related to a particular object. In the programming models like Structural, procedural and Modular programming, there was not much provision to safeguard the data from the other procedures or functions. This can lead to the misuse of data or even the design by responsibility principle of OOAD can be some times breached. Every Object in Object oriented programming has full control of what members(Fields and methods) to be accessible to its peers in a package, outside the package and should only be visible to its own members alone. Encapsulation in Object Oriented Programming is implemented by mentioning the Access Modifiers l...
