How to Split an Array in Kotlin ?

Answer

To split an array in Kotlin, you can use the sliceArray method to create subarrays from the original array.

✐ Examples

1 Split Array of Integers into Two Subarrays

In this example,

We create an array named arr with integer values.
We use the sliceArray method to create a subarray containing the first three elements of arr. This is done by passing a range (0..2) to the sliceArray method.
We use the sliceArray method again to create another subarray containing the remaining elements of arr. This is done by passing a range (3 until arr.size) to the sliceArray method.
Finally, we print both subarrays to standard output.

Kotlin Program

fun main(args: Array<String>) {
    val arr = arrayOf(1, 2, 3, 4, 5, 6)
    val firstHalf = arr.sliceArray(0..2)
    val secondHalf = arr.sliceArray(3 until arr.size)
    println("First half: ${firstHalf.joinToString()}")
    println("Second half: ${secondHalf.joinToString()}")
}

Output

First half: 1, 2, 3
Second half: 4, 5, 6

2 Split Array of Strings into Two Subarrays

In this example,

We create an array named arr with string values.
We use the sliceArray method to create a subarray containing the first two elements of arr. This is done by passing a range (0..1) to the sliceArray method.
We use the sliceArray method again to create another subarray containing the remaining elements of arr. This is done by passing a range (2 until arr.size) to the sliceArray method.
Finally, we print both subarrays to standard output.

Kotlin Program

fun main(args: Array<String>) {
    val arr = arrayOf("apple", "banana", "cherry", "date")
    val firstHalf = arr.sliceArray(0..1)
    val secondHalf = arr.sliceArray(2 until arr.size)
    println("First half: ${firstHalf.joinToString()}")
    println("Second half: ${secondHalf.joinToString()}")
}

Output

First half: apple, banana
Second half: cherry, date
