What are some examples of data classes in programming?

Data classes are a feature in many programming languages that simplify the creation of classes used to store data. For example, in Python, you can use the @dataclass decorator to automatically generate special methods like __init__() and __repr__().

Can you show me a Python example?

Sure! Here's a simple example:

from dataclasses import dataclass

@dataclass
class Point:
    x: int
    y: int

This creates a Point class with x and y attributes.

What about data classes in Java?

In Java, you can use records, which are a similar concept introduced in Java 14. Here's an example:

record Point(int x, int y) {}

This defines a Point record with x and y fields.

Are there data classes in other languages?

Yes, many languages have similar constructs. For instance, Kotlin has data classes, and C# has record types. Each serves the purpose of simplifying data handling.
