adatosztályok

Adatosztályok, often translated as data classes, are a feature found in various programming languages designed to simplify the creation of classes that primarily store data. They typically reduce boilerplate code by automatically generating methods such as constructors, getters, setters, and equality checks based on the fields defined within the class. The main purpose of an adatosztály is to encapsulate data in a structured and organized manner.

The concept of adatosztályok aims to make code more readable and maintainable, especially when dealing with numerous simple data structures. Instead of manually writing repetitive code for basic object functionalities, developers can declare the data fields, and the language's compiler or runtime environment handles the rest. This leads to more concise code and fewer opportunities for common programming errors.

Different programming languages implement adatosztályok with varying syntax and capabilities. For instance, some might offer immutability by default, meaning once an adatosztály object is created, its data cannot be changed. Others might provide features for easy copying and modification of objects while preserving the original. The core idea, however, remains consistent: to provide a streamlined way to define data-holding objects. Adatosztályok are particularly useful in scenarios like representing database records, API responses, or simple configuration settings.
