Kotlin - Inner Class Example

An inner class is a class which is created inside another class with keyword inner. In other words, we can say that a nested class which is marked as "inner" is called inner class.

Kotlin Inner Class Example

package net.javaguides.kotlin class outerClass { private var name: String = "Ramesh" inner class innerClass { var description: String = "code inside inner class" private var id: Int = 101 fun foo() { println("name is ${name}") // access the outer class member even private  println("Id is ${id}") } } } fun main(args: Array < String > ) { println(outerClass().innerClass().description) // accessing property  var obj = outerClass().innerClass() // object creation  obj.foo() // access member function  }
Output:
code inside inner class name is Ramesh Id is 101
