Can you name and describe the visibility scopes of various access modifiers in Kotlin?

In Kotlin, the following access modifiers define the visibility scope of elements:

• public (default): accessible from anywhere in the project.
• internal: accessible only within a single module (e.g., one Gradle module).
• protected: accessible within the class and its subclasses.
• private: accessible only within the file or class where it is declared.

Example:

class Example {
    private val secret = "private"
    protected val semiSecret = "protected"
    internal val moduleSecret = "internal"
    val publicInfo = "public" // public by default
}

Thus, modifiers allow controlling where and how variables, functions, and classes can be used, ensuring encapsulation and code security.
