5/26/2023 0 Comments Kotlin internal class meaning![]() ![]() Per this link, “classes, objects, interfaces, constructors, functions, properties and their setters can have visibility modifiers. Is the equivalent of this Java code: public class Person public means that any client who sees the declaring. With the exception of the names of the getter and setter functions, if you’re coming to Kotlin from Java, this Kotlin code: class Person(var firstName: String, var lastName: String) internal means that any client inside this module who sees the declaring class sees its internal members. You can think of them as being like function calls: val f = Foo() Reusability: Nested and inner classes can be reused within the same class or across multiple classes. New instances of classes are created without the new keyword. Advantages of using nested and inner classes in Kotlin: Encapsulation: Nested and inner classes allow you to group related functionality together and keep it separate from the rest of the code, improving code organization and readability. I show annotations and visibility modifiers at the end of this lesson. If the primary constructor does not have any annotations or visibility modifiers, the constructor keyword can be omitted: class Person(var firstName: String, var lastName: String) The primary constructor is part of the class header.
