How to do it…

In every real-world project, you create classes that don't have any use except for storing data, like in the case of the Student class we described earlier. The number of these types of classes can be way too high in a complex project having many roles and models. This results in a lot of boilerplate code. Kotlin has a great solution for it:

data class Student(var name:String,var roll_number:String,var age:Int)

That's it!

2. Now, let's try to use the data class we just created:

fun main(args: Array<String>) {    val student=Student("Aanand","2013001",21)    println("Student: name- ${student.name}, roll_number:${student.roll_number}, age:${student.age
