SETOF() - FUNCTION

Using the setOf() method, we can create an immutable set(i.e. A read only Set).

fun main() {
    var x = setOf(5, "John", "Kotlin")
    println(x)
}

Output :

[5, John, Kotlin]

So, in the above code we have created a Set using the setOf() method.

And put an Integer type value (i.e. 5) and two String type value (i.e. John and Kotlin)

var x = setOf(5, "John", "Kotlin")

And initialised to the variable x.

So, we can see that two different data types are assigned to a Set.

In the next line we have printed the Set using the print statement.

println(x)

Now, if we see the output,

[5, 'John', 'Kotlin']

The values are enclosed inside square brackets []. This means that the values are inside a Set.
