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

How to Convert a Set of Floats to a Set of Strings in Kotlin ?

Answer

To convert a set of floats to a set of strings in Kotlin, you can use the map function to transform each float element into its string representation and then convert the resulting list back to a set.


✐ Examples

1 Convert Set of Floats to Set of Strings Example 1

In this example,

  1. First, we create a set named floatSet containing the float values 1.1f, 2.2f, and 3.3f.
  2. Next, we use the map function on floatSet. The map function transforms each element in the set by applying the given lambda function { it.toString() }, which converts each float to its string representation.
  3. The result of the map function is a list of strings, so we convert this list back to a set using the toSet method to ensure that the result is a set of strings.
  4. We store the resulting set of strings in a variable named stringSet.
  5. Finally, we print the value of stringSet to standard output using println.

Kotlin Program

fun main() {
    val floatSet = setOf(1.1f, 2.2f, 3.3f)
    val stringSet = floatSet.map { it.toString() }.toSet()
    println("Set of strings: $stringSet")
}

Output

Set of strings: [1.1, 2.2, 3.3]

2 Convert Set of Floats to Set of Strings Example 2

In this example,

  1. We start by defining a set named floatSet2 that contains the float values 4.4f, 5.5f, and 6.6f.
  2. We then call the map function on floatSet2. The map function iterates over each element in the set and applies the lambda function { it.toString() } to convert each float to its string representation.
  3. This map function produces a list of strings as its result. We then convert this list to a set using the toSet method to maintain the uniqueness property of the set.
  4. The resulting set of strings is stored in a variable called stringSet2.
  5. Finally, we print the value of stringSet2 to standard output using println.

Kotlin Program

fun main() {
    val floatSet2 = setOf(4.4f, 5.5f, 6.6f)
    val stringSet2 = floatSet2.map { it.toString() }.toSet()
    println("Set of strings: $stringSet2")
}

Output

Set of strings: [4.4, 5.5, 6.6]
