And also, if we do not specify any access modifier it. In Java, we can access a protected member from the same package, but in Kotlin a protected member is only visible in the class and its subclasses. Default: We can access the default modifier only within the same package and not from outside the package. It restricts the visibility to within the file where they are declared. In Kotlin we can use private modifier on top-level declarations, including classes, functions, and properties. In case of Java, the encapsulation can be easily broken, we can write an external code with the same packages name and thus get access to classes of that package declarations. Internal modifier provides real encapsulation in Kotlin. A module is a set of Kotlin files compiled together(like Android Studio or Eclipse Project). Kotlin has a new visibility modifier – internal. Kotlin uses packages only to organizing code it has nothing to do with visibility control like java. Similar to Java we have same public, protected, and private modifiers in Kotlin. Modifiers for class Kotlin Class Modifiers Visibility modifiers It exposes the class, field, or method to any other code outside of the class. Additionally, it works the same as in Java. We can use public, private, or internal restriction keywords. It is abstract if it has no body, but no need to specify abstract modifier. Now, let’s have a look at the default modifier in Kotlin. In case of interfaces, we don’t use final, open, or abstract. In the above program, turnOn () and turnOff () member functions are public whereas, isOn property is private. If you do not specify the visibility modifier, it will be public by default. You will learn about protected and internal modifiers later in Kotlin visibility modifiers article. The the table listed below is for modifiers for classes in Kotlin. internal - any client inside the module can access them.
