Copilot Kotlin: Convert a list of numbers to string

In Kotlin, converting a list of numbers into a single string is a common task that can be done efficiently using built-in functions. This example demonstrates how to transform a list of integers into a formatted string, making it easy to display or log the values.

Code

fun main() {
  val numbers = listOf(1, 2, 3, 4, 5)

  // Convert the list of numbers to a comma-separated string
  val result = numbers.joinToString(separator = ", ")

  println(result)  // Output: 1, 2, 3, 4, 5
}

Key Points

• The Kotlin function joinToString() converts collections into formatted strings easily.
• You can specify a separator such as a comma, space, or any string between elements.
• This method works with any collection of elements, not just numbers.
• Using joinToString() keeps code concise and readable compared to manual loops.
