In this issue, the editor will bring you about how to learn object-oriented programming language. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

The basic theoretical points of object-oriented programming language:

Learn basic theoretical points, such as design patterns / paradigms, so that you know what you have in common in all object-oriented programming languages, rather than improving one language level. This is the most effective way to learn a programming language.

There are many types of programming languages, such as functional languages, object-oriented languages, data-oriented languages (more). By summarizing and classifying various languages, these 600 languages can be roughly divided into 50 categories. By learning the basic theoretical points of each classification, it becomes much easier to learn different languages in the classification. Let me give you an example here.

For object-oriented programming languages, there are five basic principles that can help you write clean and excellent code. These principles are summarized by Bob Martin and are called SOLID principles. Here is an article that explains these principles well in the form of pictures. These principles are:

An object has only one responsibility, and all service interfaces perform this task only through it.

Program entities, such as classes and objects, are open to extension behavior and closed to modification behavior.

A subclass should be able to replace the class it inherits.

The dependency of one class on another should be limited to minimized interfaces.

Rely on the abstraction layer (interface), not the concrete class.

By learning these principles, you can program more effectively in all object-oriented languages. Of course, you need to learn a language of this type to practice these principles, but it's totally worth it.

Differences between various object-oriented languages:

Both belong to object-oriented languages, and there are a lot of differences between them:

Grammar: there are many advantages to understanding the differences in grammatical sentence patterns between different languages, one of which can help optimize your coding. This makes the program easier to understand by keeping the behavior of a method or class similar to its behavior.

Uniqueness: each programming language has its own uniqueness compared to others. Java has the characteristics of private methods and data customization, and Ruby has a strong advantage in Web applications.

In a word, it is important to learn the differences between different languages. This language may be easier to use or more powerful than some aspects of that language.

The most effective way to learn programming languages is to learn their basic patterns / paradigms, which is more efficient than learning each language alone. By learning these basic principles, you can apply them to many other similar languages. Learning the differences between different languages can help us choose a more appropriate language in the face of various situations.

The above is the editor for you to share how to learn object-oriented programming language, if you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
