Can you explain the purpose and use of the Any type in Kotlin?

In Kotlin, the Any type is the root type for all types, similar to Object in Java. Any object in Kotlin is a descendant of Any.

Purpose of Any:

• Used when working with objects of unknown type.
• Allows storing values of any type but does not have specific methods other than the basic ones (equals(), hashCode(), toString()).

Example of usage:

fun printAny(value: Any) {
    println(value.toString())
}

printAny(123)          // output: 123
printAny("Hello")    // output: Hello

If you need to work with nullable values of any type, Any? is used, which can contain null.

Thus, Any serves as a universal type for generic functions and variables.
