Konstruktoralapú

Konstruktoralapú refers to a programming paradigm or approach where object-oriented programming relies heavily on constructors for object initialization. In this paradigm, the primary mechanism for creating and setting up new objects is through specialized methods called constructors. These constructors are typically named the same as the class they belong to and are automatically invoked when an instance of the class is created.

The core idea behind a konstruktoralapú approach is that an object's state should be defined or at least significantly influenced at the moment of its creation. This often involves passing parameters to the constructor, which are then used to set the initial values of the object's attributes or properties. This contrasts with approaches where objects might be created with default values and then modified through separate setter methods.

This paradigm promotes encapsulation by ensuring that objects are always in a valid and well-defined state upon instantiation. It can lead to more robust and easier-to-understand code, as the initialization logic is centralized within the constructor. Many popular object-oriented languages, such as Java, C++, and C#, naturally support and encourage a konstruktoralapú style of programming through their constructor mechanisms. The use of constructors can also facilitate code reusability and the implementation of design patterns like the factory pattern.
