How to create a Set of Strings in Kotlin - Step by Step Examples



How to create a Set of Strings in Kotlin ?

Answer

To create a set of strings in Kotlin, you can use the mutableSetOf function or the setOf function.



✐ Examples

1 Create Set of Strings using mutableSetOf

In this example,

  1. We use the mutableSetOf function to create a mutable set of strings.
  2. We add strings to the set using the add method.
  3. The resulting set contains unique strings in no particular order.

Kotlin Program

fun main() {
    // Create a mutable set of strings
    val stringSet = mutableSetOf<String>()

    // Add strings to the set
    stringSet.add("Apple")
    stringSet.add("Banana")
    stringSet.add("Cherry")

    // Print the set
    println(stringSet)
}

Output

[Apple, Banana, Cherry]

2 Create Set of Strings using setOf

In this example,

  1. We use the setOf function to create an immutable set of strings.
  2. The resulting set contains unique strings in no particular order.

Kotlin Program

fun main() {
    // Create an immutable set of strings
    val stringSet = setOf("Apple", "Banana", "Cherry")

    // Print the set
    println(stringSet)
}

Output

[Apple, Banana, Cherry]
