Definition and origin of the object-oriented paradigm
Object-oriented programming (OOP) is a computer programming model that implements an object-based design. It differs from procedural programming, which is based on the use of procedures, and from functional programming, which is based entirely on the concept of function.
During the 1980s, the enthusiasm for object-oriented languages began: Eiffel, C++, or Objective C (an object extension of C used by Apple’s iOS). This enthusiasm peaked in the 1990s with the extension of object-based programming in various software development sectors and the Java language’s creation.
Even though programming was considered a tremendously challenging job, which required a lot of knowledge and hard work, OOP became an essential paradigm for any computer scientist and self-respecting application developer. And many doors of opportunities, one of which is, for example, https://wowassignment.com/computer-science-homework-help/, have opened to those who study object-oriented programming and must deal with coding tasks in any programming language.
Nowadays, many languages allow OOP principles in various domains: Java and C#, of course, but also PHP (from version 5), Python, etc. Object Oriented Programming has significantly changed how the architecture of computer applications is conceived. When modeling an application, we now think in terms of objects: this is object-oriented modeling (OOM), whose primary support is the UML modeling language.
Object-oriented languages
As mentioned above, the object-oriented language boom began in 1980 and peaked in the 1990s. Before going into the characteristics of these languages, it is good to recall the main advantages of the object-oriented paradigm:
- modularity: the objects form compact modules regrouping data and a set of operations;
- abstraction: OOP objects are close to those of the real world;
- productivity and reusability: the more complex the application is, the more interesting the OOP approach is. The level of reusability is higher than in procedural programming;
- security: the encapsulation and typing of classes offer certain robustness to applications.
Let’s go back to the object languages themselves. Simula (1967) is generally recognized as the first object-oriented language. It was created to realize simulation programs. Smalltalk (1972 to 1980) is another early example with which much of the OOP theory was developed.
There are several categories of object-oriented languages. They depend on the degree of use of objects and the level of integration of the language with the object-oriented paradigm:
- so-called “pure” OOP languages, where everything is treated as an object, from primitives such as characters and punctuation to classes, prototypes, blocks, and modules. They have been explicitly designed to facilitate or even impose object-oriented methods. Ex: Ruby, Scala, Smalltalk, Eiffel, Emerald, JADE, Self, Raku;
- languages designed mainly for OOP but with some procedural elements. Ex: Java, Python, C++, C#, Delphi/Object Pascal, and others;
- languages that are historically procedural but have been extended with some object-oriented features. Ex: PHP, Perl, Visual Basic (derived from BASIC), MATLAB, C++, C#, COBOL 2002, Fortran 2003, ABAP, Ada 95, Pascal;
- languages with most of the characteristics of objects (classes, methods, inheritance) but in an original form. Ex: Oberon (Oberon-1 or Oberon-2);
- languages with support for abstract data types that can be used to resemble OOP but without all the characteristics of object-oriented programming. Ex: JavaScript, Lua, Modula-2, CLU.
Object-oriented programming has become particularly popular in dynamic programming languages in recent years. Python, PowerShell, Ruby, and Groovy are dynamic languages built on OOP principles, while Perl and PHP have added object-oriented features since Perl 5 and PHP 4 and ColdFusion since version 6. Although there are many object-oriented languages on the market today, the market is mainly dominated by the Java language.
Conclusion
Since a lot of knowledge is required for a programmer to obtain to start working with dynamic languages, it isn’t very reasonable to consider OOP an easy pathway for a novice in coding. However, having an aspiration to build an incredibly successful career in programming, it is helpful at least to know about object-oriented programming. I hope you expanded your horizons and learned something new from this article. Remember that a good programmer always works on himself and does not avoid difficulties because the thorniest way always brings the most progress.
