What are some examples of data class usage in programming?

Data classes are used to create classes that primarily store data. For example, in Python, you can define a data class to represent a point in 2D space.

Can you show me a code example of a data class in Python?

Sure! Here's a simple example:

from dataclasses import dataclass

@dataclass
class Point:
    x: int
    y: int

This defines a data class Point with two attributes, x and y.

What are the benefits of using data classes?

Data classes reduce boilerplate code, provide a clear structure for data, and automatically generate methods like __init__, __repr__, and __eq__.

Are there data classes in other programming languages?

Yes, many languages have similar constructs. For example, Kotlin has data classes, and C# has record types that serve a similar purpose.
