map Size in Kotlin

In Kotlin, the size of a hash can be obtained by using the size property of a HashMap. Here's an example:

fun main() {
   val hash = hashMapOf("apple" to 2, "orange" to 4, "banana" to 1)
   val size = hash.size
   println("The size of the hash is: $size")
}

In this example, we have created a HashMap that contains three key-value pairs. We have then used the size property to obtain the size of the hash. The println statement prints the size of the hash.

Output:

The size of the hash is: 3
