How to Copy a Set in Kotlin

How to Copy a Set in Kotlin ?

Answer

To copy a Set in Kotlin, you can use the copy constructor or the toSet() method.


✐ Examples

1 Copy a Set using Copy Constructor

In this example,

  1. We have an existing Set named originalSet with some elements.
  2. We create a new Set named copiedSet using the copy constructor Set(originalSet).
  3. The copy constructor creates a new Set with the same elements as the original Set.

Kotlin Program

val originalSet = setOf("apple", "banana", "cherry")
val copiedSet = HashSet(originalSet)
println("Original Set: $originalSet")
println("Copied Set: $copiedSet")

Output

Original Set: [apple, banana, cherry]
Copied Set: [apple, banana, cherry]

2 Copy a Set using toSet() Method

In this example,

  1. We have an existing Set named originalSet with some elements.
  2. We create a new Set named copiedSet using the toSet() method on the original Set.
  3. The toSet() method returns a new Set with the same elements as the original Set.

Kotlin Program

val originalSet = setOf("apple", "banana", "cherry")
val copiedSet = originalSet.toSet()
println("Original Set: $originalSet")
println("Copied Set: $copiedSet")

Output

Original Set: [apple, banana, cherry]
Copied Set: [apple, banana, cherry]
