MUTABLESETOF() - FUNCTION

Using the mutableSetOf() method, we can create a mutable set(i.e. The Set values can be changed/replaced).

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

Output :

[5, 'John', 'Kotlin']

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

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

var x = mutableSetOf(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.
