kotlin join strings from list
import kotlin.collections.joinToString
val list = listOf("Hello", "World", "Kotlin") val result = list.joinToString(separator = " ")
The above code demonstrates how to join strings from a list using Kotlin's joinToString
function. Here is an explanation of each step:
We import the
joinToString
function from thekotlin.collections
package. This function allows us to convert a collection (in this case, a list) into a single string.We create a list called
list
with three elements: "Hello", "World", and "Kotlin". This list will be used to demonstrate thejoinToString
function.We call the
joinToString
function on thelist
variable. This function takes several parameters, but in this case, we only use theseparator
parameter. Theseparator
parameter specifies the string that should be inserted between each element of the list when they are joined together.We pass the value
" "
(space) as theseparator
parameter. This means that each element of the list will be separated by a space when they are joined together.The result of the
joinToString
function is stored in theresult
variable. In this case, theresult
variable will contain the string "Hello World Kotlin", with each element of thelist
separated by a space.
That's it! The result
variable now contains the joined string from the list
using the joinToString
function with a space as the separator.
