objektikoodista

Objektikoodi, also known as object-oriented programming (OOP), is a programming paradigm based on the concept of "objects", which can contain data in the form of fields (often known as attributes or properties), and code, in the form of procedures (often known as methods). In OOP, computer programs are designed by making them out of objects that interact with one another. There are four basic principles of OOP: encapsulation, abstraction, inheritance, and polymorphism.

Encapsulation is the bundling of data with the methods that operate on that data. It restricts direct access to some of an object's components, which is a means of preventing accidental interference and misuse of the methods and data. Abstraction is the concept of hiding the complex implementation details and showing only the essential features of the object. Inheritance is a mechanism where one class acquires the properties and methods of another class. It promotes code reusability. Polymorphism allows methods to do different things based on the object it is acting upon, meaning that a call to a member function will cause a different function to be executed depending on the type of object that invokes the function.

OOP is used in many programming languages, including Java, C++, Python, and Ruby. It is particularly useful for large, complex software systems, as it allows for better organization and management of code. However, it can also be more complex and harder to learn than other programming paradigms.
