Instanssiointi

Instanssiointi, also known as instantiation in English, is a fundamental concept in object-oriented programming and computer science. It refers to the process of creating an instance of a class, which is a specific realization of any object. When a class is instantiated, memory is allocated for the object, and the object's properties and methods are initialized according to the class definition.

The instantiation process typically involves calling a constructor method, which is a special function defined within the class. The constructor initializes the object's state by setting initial values for its properties. For example, in Python, the constructor method is named __init__.

Instantiation is crucial for creating multiple objects from a single class definition, each with its own unique state and behavior. This allows for the creation of complex systems where objects interact with each other through their methods and properties.

In summary, instanssiointi is the mechanism by which objects are created from class definitions, enabling the development of modular and reusable code in object-oriented programming.
