Kotlin Data Class

Many times in the real world, we create classes solely for the purpose of holding data and nothing else. Kotlin provides a compact way of creating such classes called Data class.

Example:- Customer class, Employee class etc.
Data classes in Kotlin allow us to create class with only data.

Example of Data class in Kotlin.
In the following example, we created a data class Employee with employee Id and employee Name. We are then able to create and access the employee object just like a regular class object.

data class Employee(val empId: Int, val empName: String)

fun main(args: Array<String>)
{	
 	var employee = Employee(1723, "Mugambo")
    
    println(employee.empId)
    println(employee.empName)
}

Output:
1723
Mugambo
