How to get Sub Array in Kotlin

How to get Sub Array in Kotlin ?

Answer

To get a subarray from a given array in Kotlin, you can use the sliceArray() method or the array slicing syntax.


✐ Examples

1 Get Subarray from Integer Array

In this example,

  1. We create an integer array named numbers with some elements.
  2. We get a subarray of the array from index 1 to 3 using the sliceArray() method and store the result in the variable subArray.
  3. Finally, we print the subarray to standard output.

Kotlin Program

fun main() {
    val numbers = intArrayOf(1, 2, 3, 4, 5);
    val subArray = numbers.sliceArray(1..3);
    println("Subarray: ${subArray.contentToString()}");
}

Output

Subarray: [2, 3, 4]

2 Get Subarray from String Array

In this example,

  1. We create a string array named words with some elements.
  2. We get a subarray of the array from index 1 to 3 using the sliceArray() method and store the result in the variable subArray.
  3. Finally, we print the subarray to standard output.

Kotlin Program

fun main() {
    val words = arrayOf("apple", "banana", "cherry", "date", "elderberry");
    val subArray = words.sliceArray(1..3);
    println("Subarray: ${subArray.contentToString()}");
}

Output

Subarray: [banana, cherry, date]
