The protected access modifier is accessible only within the same class and additionally from all the subclasses of its class. The private modifier is the most restrictive access level. Methods, variables, and constructors that are declared private can only be accessed within the declared class itself. So, the private access modifier is accessible only within the class. There are four access modifiers in Kotlin, and to be specific, the first one is private. Access modifiers are used for setting the access level to classes, variables, functions, and constructors. So, in this video here we're going to learn access modifiers or visibility modifiers in Kotlin. If you want to see more examples on Kotlin Visibility Modifiers, please go to my GitHub.Well, hello everyone. We have seen some of the basics of Visibility Modifiers in Kotlin.

N.B: Classes with private constructors cannot be instantiated using that constructor. Externally visible packages should be imported when they have to be used. If a visibility modifier is not specified, public would be used by default. A Kotlin module could be an IntelliJ IDEA module, a maven project, a gradle source set or a set of files compiled with one invocation of the Ant task. A module is a software component that contains one or more functions that are usually compiled together.

If a declaration is marked internal, it is visible everywhere in the same module.

The protected declaration is not available for packages.

If a declaration is marked private, it is visible inside the file containing the declaration.

If a declaration is marked public, it is visible everywhere.

Packages are actually used to organize a set of classes, objects, interfaces, functions and properties that are related. There are four visibility modifiers in Kotlin:Ĭlasses, Objects, Interfaces, functions and properties can be declared directly inside a package. Visibility modifiers are keywords that set the accessibility of classes, objects, interfaces, constructors, functions, properties and their setters. In this article, we would cover visibility modifiers in Kotlin. In my previous article, I wrote about classes in the Zero to Kotlin Hero series.
