Microsoft Visual Basic developers have long clamored for complete objectoriented language support. Microsoft Visual Basic .NET supports all the features of an objectoriented language. In addition, the entire Microsoft .NET Framework, which includes the development support for Microsoft Windows applications, Web applications, Web services, graphics, and data access, is designed according to object-oriented principles.
Developers who have a firm grasp of object-oriented principles will be the strongest .NET
Over the past decade, PHP has transformed itself from a set of simple tools for web site development
to a full-fledged object-oriented programming (OOP) language. PHP now rivals mainstream
languages like Java and C# for web application development, with more and more enterprises
turning to it to power their web sites. The reasons for this are clear: PHP has found the right
combination of an easy-to-learn language and powerful features.
Object-oriented programming is largely about the ability to hide what's not important
to the user and to highlight what is. PHP 5 offers standardized means for specifying
the variety of property scopes typically offered by full-featured OO languages.
Most great programming books sway far more toward the realm of the practical
than of the academic. Although I have no illusions regarding my place among the
great technical authors of our time, it is always my goal to write with this point in
mind, producing material that you can apply to your own situation. Given the size
of this book, it’s probably apparent that I attempted to squeeze out every last drop of
such practicality from the subject matter.
Programming (OOP) features and popular Open Source libraries.
All solutions and code in the books have been reviewed and approved by today’s top PHP experts, including Kevin Yank, author of the best-selling "Build Your Own Database-Driven Website
While there is a study guide (available from Ventus) that focuses largely on objects and their
characteristics, it will be instructive to the learner (of the Java programming language) to understand how
the concept of an object is applied to their construction and use in Java applications.
Inheritance and Polymorphism
Welcome to the module Inheritance and
Inheritance is a process of creating a new
class from an existing class.
Inheritance allows you to inherit attributes
and methods of the base class in the newly
Polymorphism is a feature of OOP that allows
the data members of a class to behave
differently based on their parameters and
In this module, you will learn about:
When you begin a new project, one of the first things you have to consider is the structure of your
code. Whether you’re coding something as simple as an online contact form, or as complex as a
full-featured content management system, how you organize your code is going to influence the
performance and maintainability of the end product.
When you use a language like PHP, there are two main routes you can go: procedural programming
and object-oriented programming—OOP for short. Each strategy has its own benefits and
