A Data Class is a special type of class in programming, particularly in languages like Python and Kotlin, designed to hold and manage data. It automatically generates common methods such as __init__, __repr__, and __eq__, which simplifies the process of creating classes that primarily store values. This reduces boilerplate code and makes it easier to work with data structures. Data classes are useful for organizing related data in a clear and concise manner. They allow developers to define attributes and their types, making the code more readable and maintainable. By using data classes, programmers can focus on the logic of their applications without getting bogged down by repetitive code.
