The classes, methods, packages and other properties can be declared with a private modifier. Though above example can be written with public modifier explicitly as follows: In the above example, we have not mentioned any modifier, so the method and variable defined here, are by default public. Following is an example to understand more on how to declare a public variable or method. In all our previous examples, we have not mentioned any modifier, hence, all of them are in the public scope. If no access modifier is specified, then by default it will be in the public scope. Public modifier is accessible from anywhere in the project workspace.
Let's look into the detail of these modifiers: Public Modifier These modifiers can be used at multiple places such as class header or method body. There are four visibility modifiers in Kotlin: Setters are the functions which are used to set the values of the properties, where as getters are the functions which are used to get the values of those properties. Though getters always have the same visibility as their properties, so we can not set their visibility.
The Kotlin visibility modifiers are the keywords that set the visibility of classes, objects, interface, constructors, functions as well as properties and their setters.
