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:

  1. We import the joinToString function from the kotlin.collections package. This function allows us to convert a collection (in this case, a list) into a single string.

  2. We create a list called list with three elements: "Hello", "World", and "Kotlin". This list will be used to demonstrate the joinToString function.

  3. We call the joinToString function on the list variable. This function takes several parameters, but in this case, we only use the separator parameter. The separator parameter specifies the string that should be inserted between each element of the list when they are joined together.

  4. We pass the value " " (space) as the separator parameter. This means that each element of the list will be separated by a space when they are joined together.

  5. The result of the joinToString function is stored in the result variable. In this case, the result variable will contain the string "Hello World Kotlin", with each element of the list 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.
