In Kotlin, a data class is a special type of class that is primarily used to hold data. It is concise, immutable by default, and automatically provides several utility methods such as equals(), hashCode(), toString(), copy(), and component functions for property access.
To declare a data class in Kotlin, you use the data modifier before the class keyword. For example:
kotlin data class Person(val name: String, val age: Int)
In this example, Person is a data class with two properties: name and age.
Data classes automatically generate implementations for commonly used methods based on the properties declared in the primary constructor. This eliminates the need for boilerplate code and enhances productivity by focusing on the data’s essence rather than its management.
Data classes are ideal for representing entities or value objects in the domain model of an application. They encapsulate data and behavior related to the data, promoting encapsulation and separation of concerns.
