How to Split a List in Kotlin


How to Split a List in Kotlin ?

Answer

To split a list in Kotlin, you can use the subList method or chunked method for more complex splitting.



✐ Examples

1 Split a List Using subList

In this example,

  1. We create a list named numbers with initial integer values.
  2. We use the subList method to create a sublist from the original list, specifying the start and end indices.
  3. The subList method returns a view of the specified range within the original list.
  4. Finally, we print the sublist to standard output.

Kotlin Program

fun main() {
    val numbers = listOf(1, 2, 3, 4, 5, 6)
    val sublist = numbers.subList(2, 5)
    println("Sublist: $sublist")
}

Output

Sublist: [3, 4, 5]

2 Split a List into Chunks Using chunked

In this example,

  1. We create a list named numbers with initial integer values.
  2. We use the chunked method to split the list into smaller lists of a specified size.
  3. The chunked method returns a list of lists, where each inner list contains elements from the original list.
  4. Finally, we print the list of chunks to standard output.

Kotlin Program

fun main() {
    val numbers = listOf(1, 2, 3, 4, 5, 6, 7, 8)
    val chunkedList = numbers.chunked(3)
    println("Chunked list: $chunkedList")
}

Output

Chunked list: [[1, 2, 3], [4, 5, 6], [7, 8]]
