Abstraction is a filtering action. It is performed by Computer Programmers. Filtering helps Programmers in coding. Coding supported by Abstraction lays emphasis on inclusion of code in a Computer Program that is essential.
Code that can shift the focus away from the problem is simply shown the door. Capability of a code to add value is the criterion for filtering. Coding away from the focal point hardly serves the problem. Relevant coding helps to perform Object Oriented Programming.
If our coding activity is based on the golden principle of Abstraction, a good Program is born. Good quality code is produced if our ideas are short and smart. Indeed it's good to play with Abstraction right from the very beginning of coding activity. Sticking to Abstraction till the end of coding activity is strongly recommended.
The simplicity and compactness that result from Abstraction marvels Object Oriented Programming Paradigm. Abstraction allows us to make the best use of Computing power. We save memory space and this helps.
Abstraction is readily supported by Programming Languages like C++ and Java. C++ and Java come with a superb layout called 'class'. 'class' concept helps to translate Abstraction activity that forms a concise solution.
The data set of the problem and coded operation units are available in the form of a capsule. This capsule of combined data and code is our 'class'. This act of combining is called Encapsulation of data and code. Yes, Encapsulation is putting together the data part and the code segment in a block.

The 'class' structure supports Abstraction in a big way. Our ideas take the form of a code very easily. This code is characterised by compactness. The code is well-proportioned. So, life with the 'class' concept is easygoing.
