You can create a class like this:
data class MyClass(
val department: String? = null,
val data: Array<Employee>? = null
)
Comments
Write a data class, which will generate several things for you including a constructor and just give it an Array<Employee>:
/**
* A data class accepting an array of employees as constructor argument
*/
data class MyClass(val department: String, val employees: Array<Employee>)
/**
* Dummy class to make this work
*/
data class Employee(val name: String)
/**
* Main function
*/
fun main() {
// create an array of employees
var a1 = Array(5) {
Employee("Mister Money");
Employee("Monsieur Monétaire");
Employee("Señor Dinero");
Employee("Herr Geld");
Employee("Signore denaro")
}
// and pass it to a new instance of Employee
val myInstance = MyClass("Finance", a1)
// then print that instance
println(myInstance)
}
Output of printing the created instance of MyClass:
myClass(department=Finance, employees=[Employee(name=Signore denaro), Employee(name=Signore denaro), Employee(name=Signore denaro), Employee(name=Signore denaro), Employee(name=Signore denaro)])
