esinepohjainen

Esinepohjainen, often translated as object-oriented, refers to a programming paradigm that organizes software design around data, or objects, rather than functions and logic. This approach centers 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). The key idea is to bundle data and the operations that can be performed on that data together into a single unit.

A fundamental principle of esinepohjainen programming is encapsulation, which hides the internal state of an object and requires all interaction to be performed through the object's methods. This promotes data integrity and simplifies code maintenance by preventing direct manipulation of internal data. Another key concept is inheritance, allowing new classes to inherit properties and behaviors from existing classes, fostering code reusability and creating hierarchical relationships between objects. Polymorphism, meaning "many forms," allows objects of different classes to respond to the same method call in their own specific ways, further enhancing flexibility and extensibility.

Esinepohjainen programming languages, such as Java, Python, and C++, are widely used in software development due to their ability to manage complexity, promote modularity, and facilitate the creation of robust and scalable applications. This paradigm has become a dominant force in modern software engineering.
