1 Creating an Empty Map

We can create an empty map in Kotlin using the mapOf function, which initializes a map with no key-value pairs.

For example,

We start by declaring a variable named emptyMap. This variable will hold our empty map.
We then use the mapOf() function to create a new, empty Map object. In Kotlin, the mapOf() function initializes the map with no key-value pairs.
The newly created map is now assigned to the emptyMap variable. In this example, the map has String keys and Integer values.
We can now perform various operations on this empty map, such as adding key-value pairs, checking for the presence of keys, and retrieving values.

Kotlin Program

fun main() {
    // Declare an empty map
    val emptyMap: Map<String, Int> = mapOf()

    // Operations on the empty map
    // ...

    println(emptyMap)
}

Output

{}
