Create DTOs (POJOs/POCOs) in Kotlin

A Data Transfer Object (DTO) is a class that is used to transfer data between two systems. In Kotlin, a DTO is an object that represents data that will be sent to or received from another system.

The purpose of a DTO is to encapsulate data so that it can be transferred between two systems in a format that is convenient for both systems. In Kotlin, a DTO can be used to transfer data between two systems by using the data class keyword.

data class Account(val username: String, val email: String, val password: String, val active: Boolean)
data class Product(
var id: Int,
var description: String,
var price: Long
)

Defining as above provides an Account and Product class with the following features:

• getters and setters.
• equals()
• hashCode()
• toString()
• copy()
• component1(), component2(), …componentN()
