REMOVE() - FUNCTION

The remove() Function can be used to remove an item from the Map.

Let us say, we want to remove the entry where the Key is 5 and Value is Is a Number.

5, Is a Number

fun main() {

    var x = mutableMapOf(5 to "Is a Number", "John" to "Is a Name", "Kotlin" to "Is a Language")
    x.remove(5)
    println(x)
}

Output :

{John=Is a Name, Kotlin=Is a Language}

So, in the above code we have created a Map using mutableMapOf and Key and Value pairs.

var x = mutableMapOf(5 to "Is a Number", "John" to "Is a Name", "Kotlin" to "Is a Language")

And initialised to the variable x.

Now, we are supposed to delete the value of the Key, 5.

So, we have used the below way to update it.

x.remove(5)

And the entry for the Key 5 is deleted for the Map.

And we get the below output,

{John=Is a Name, Kotlin=Is a Language}
