Can you name the main constructors used in Data Class?

In Kotlin, a Data Class automatically generates several constructors and functions, but the main constructors that are typically used are:

• Primary constructor: declared in the class header and takes parameters for all the properties of the class.

Example:

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

Here, the primary constructor takes name and age.

• Copy constructor (copy): allows creating a copy of an object with the possibility to change some fields.

Example:

val user1 = User("Alice", 30)
val user2 = user1.copy(age = 31)

• Parameters with default values: allow creating objects with partially specified parameters.

Example:

data class User(val name: String = "Unknown", val age: Int = 0)
val user = User()

Thus, the primary constructor with parameters and the copy functionality are key constructors in a Data Class.
