The primary constructor can be declared at class header level as shown in the following example. The Kotlin primary constructor initializes the class, whereas the secondary constructor helps to include some extra logic while initializing the class. Every Kotlin class needs to have a constructor and if we do not define it, then the compiler generates a default constructor.Ī Kotlin class can have following two type of constructors:Ī Kotlin class can have a primary constructor and one or more additional secondary constructors. Whenever an object is created, the defined constructor is called automatically which is used to initialize the properties of the class.

A Kotlin constructor is a special member function in a class that is invoked when an object is instantiated.
