[Frozen Sea]

Dear Students, 

GDB for this subject will open for two days from 25^th February 2015 to 26^th February 2015.(48 Hours only ), you will be required to post your comments on topic in GDB only.

Topic for GDB is

Can Aspect Oriented Programming (AOP) replace Object Oriented Programming (OOP). Give your opinion with solid arguments.

 Note 1:- Keep you comment brief and to the point

Note 2:- GDB will not be accepted via email in any case.

oye guys ye topic handouts me kis lecture me he ??? :-D

[Oggy,,]

Bro its so simple u just read the advantags and dsadvatages on google of both aop and oop,, u finly got the reason,,oky,,, Best of luck for all students

AOP vs OOP

AOP (Aspect-oriented programming) and OOP (Object-oriented programming) are two programming paradigms. A programming paradigm is a fundamental style of computer programming. Programming paradigms differ in how each element of the programs is represented and how each step is defined for solving problems. As the name suggests, OOP focuses on representing problems using real-world objects and their behavior, while AOP deals with breaking down the programs in to separate crosscutting concerns.

What is AOP?

AOP is a programming paradigm, which deals with breaking down a program in to cohesive areas of functionality (called concerns) that cut across multiple areas, in order to increase modularity. Support for abstractions (such as classes, methods, etc.) to group and encapsulate concerns in to unique entities is provided in many other programming paradigms. But concerns (such as “Logging”) are examples of crosscutting concerns, because every logged part of the system is affected by the strategy used for logging. The main focus of all AOP implementations is to have suitable crosscutting expressions to capture all concerns in a single location.

What is OOP?

In OOP, the focus is on thinking about the problem to be solved in terms of real-world elements, and representing the problem in terms of objects and their behavior. Classes depict the abstract representations of real world objects. Classes are like blueprints or templates, which gather similar items or things that can be grouped together. Classes have properties called attributes. Attributes are implemented as global and instance variables. Methods in the classes represent or define the behavior of these classes. Methods and attributes of classes are called the members of the class. An instance of a class is called an object. Therefore, an object is a data structure that closely resembles some real-world object.

There are several important OOP concepts such as Data abstraction, Encapsulation, Polymorphism, Messaging, Modularity and Inheritance. Typically, encapsulation is achieved by making the attributes private, while creating public methods that can be used to access those attributes. Inheritance allows the user to extend classes (called sub classes) from other classes (called super classes). Polymorphism allows the programmer to substitute an object of a class in place of an object of its super class. Typically, the nouns found in the problem definition directly become classes in the program. And similarly, verbs become methods. Some of the most popular OOP languages are Java .

First of all AOP will not replace OOP. AOP extends OOP. The ideas and practices of OOP stay relevant. Having a good object design will probably make it easier to extend it with aspects.

I think the ideas that AOP brings are important. We need to work out ways to implement cross-cutting-concerns over different classes in your program without having to change the classes themselves. But I think the AOP will eventually just become part of other tools we use and not a separate tool or technique. We already see this happening.
