Can you explain what a Data Class is and what it is used for in programming?

Data Class — is a special class in programming languages (for example, Kotlin) designed for storing data. The main goal of a Data Class is to simplify the creation of classes that contain only fields and automatically provide standard methods such as equals(), hashCode(), toString(), as well as methods for copying and destructuring.

For example, in Kotlin, declaring a Data Class looks like this:

data class User(val name: String, val age: Int)

Using a Data Class allows writing less boilerplate code and makes the code more readable and maintainable. Such classes are often used for passing data between layers of an application, for example, between the UI and business logic.
