Answer

To add an item to a set in Kotlin, you can use the add method.

✐ Examples

1 Add an Item to a Set

In this example,

We have an existing set named mySet.
We use the add method to add a new item to mySet.

Kotlin Program

fun main() {
    var mySet = mutableSetOf("apple", "banana", "orange")
    println("Set before adding item: $mySet")
    mySet.add("grape")
    println("Set after adding item: $mySet")
}

Output

Set before adding item: [apple, banana, orange]
Set after adding item: [apple, banana, orange, grape]

2 Add an Integer to a Set

In this example,

We have an existing set named numberSet.
We use the add method to add a new integer to numberSet.

Kotlin Program

fun main() {
    var numberSet = mutableSetOf(1, 2, 3, 4, 5)
    println("Set before adding integer: $numberSet")
    numberSet.add(6)
    println("Set after adding integer: $numberSet")
}

Output

Set before adding integer: [1, 2, 3, 4, 5]
Set after adding integer: [1, 2, 3, 4, 5, 6]
