Modules like calling API needs to be in different modules and utilities in different modules type architecture and you don’t want to give access to some classes other than that module. “Internal” modifier is generally not going to use in android unless you have a modular architecture. While in Kotlin as you can see I’m having classes in the same package still it gives me an error that “Propertyone” is protected and can not be accessed unless and until you subclass it Kotlin not going to allow you to have access for that variable or functions. So as you can see on left side Java class can access “propertyOne” without inheriting the class even in the same package if it’s in different package class needs to be extended to access a protected property. Kotlin protected modifiers differs from Java Protected modifier ![]() ![]() Package-Private means that you can only use those functions and variables to a subclass which is in the same package and classes inside that package.Ī small diagram to hold or grasp above things: What is the default identifier in Java? I mean if you don’t specify the type of visibility modifier in java what java compiler does to that function or variable? It’s going to assign those functions and variables as “Package-Private”. Protected holds functions and variables visibility to subclass and the package level scope. ![]() Private on other hand holds the functions or variables visibility to that class only(except you can change using reflection but that’s not the point here) other classes or subclasses also do not get hold of private functions and variables. Let’s start with Java, In Java, we have Public, Private, Protected and Package-private(if you don’t know this exists will explain what it is in a moment).Īll know about “Public” modifier It’s basically accessed by all classes.
