Abstraction
It is not a mandatory feature of OOP, but it is an important part of it. Abstraction implies a set of significant characteristics of an object that are identified in the process of abstraction (separation of significant properties from insignificant ones).
Each of these concepts seems quite simple, however, when you start working, it is quite difficult to adhere to them. You need to know how classes work technically, how to implement the inheritance of a certain object, how to save a class in memory, how to build the interaction of classes, how objects should be transferred and used, and much more. You can learn all the principles of object-oriented programming from scratch in special courses . will make the start in programming easier and faster.
Advantages and disadvantages
The main advantages of OOP include:
Clarity. The code becomes simpler and easier iran email list to read. The code immediately makes it clear what a certain object is responsible for and what rules all program components interact with.
Speed of writing. This method of programming is convenient because you can immediately create the required number of blocks, filling them with minimal content, and specify the rules of operation. In the future, each component can be refined, filled with methods and properties.
Functionality. Saving time on developing the basis allows you to devote more time to content, add features, increase productivity, and diversify methods.
Reusability. There is no need to write the same functions for different components if they are duplicated.
The disadvantages include:
Complexity of the approach. In order to start working, it is necessary to study the theory, know the basics, and learn the rules.
Memory load on the device. The properties and methods inherent to each object take up much more memory than regular functions.
Due to the specifics of the approach, performance may be lower. That is why it happens that an OOP program works slower than a procedural one (although with modern processor power, this hardly bothers anyone).
Despite certain difficulties, OOP is a fairly effective approach to programming.
