Hands-On Object-Oriented Programming with Kotlin

The this keyword

The this keyword is used to refer to the object that we are currently talking about. In our current Person example, the this keyword refers to the Person object. Take a Person class example and append the this keyword with each property:

class Person(pName: String, pAge: Int, pHeight : Double ) {     var name : String     var age : Int     var height : Double     init {         this.name = pName         this.age = pAge         this.height = pHeight     } }

The this keyword refers to the name, age, and height properties of the current object. The this keyword is optional and the main reason to use it is to remove the ambiguity between the class property and the local parameter.
