TOMUTABLEMAP() - FUNCTION

The toMutableMap() method is used to copy one Map to the other creating a mutable Map.

Example :

fun main() {

    var x = mutableMapOf(5 to "Is a Number", "John" to "Is a Name", "Kotlin" to "Is a Language")
    var y = x.toMutableMap()
    println("The Copied Map is "+y)
}

Output :

The Copied Map is {5=Is a Number, John=Is a Name, Kotlin=Is a Language}

So, in the above code we have created a Map and initialised to the variable x.

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

Then we have taked the Map x and called the toMutableMap() method that creates a new Map that would be the exact copy of x.

Then assign it to y.

	var y = x.toMutableMap()

And if we see the below output,

The Copied Map is {5=Is a Number, John=Is a Name, Kotlin=Is a Language}

The new variable y is an exact copy of x.
