How to get Sub Array in Kotlin - Step by Step Examples
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,
- We create an integer array named
numbers
with some elements. - We get a subarray of the array from index 1 to 3 using the
sliceArray()
method and store the result in the variablesubArray
. - 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,
- We create a string array named
words
with some elements. - We get a subarray of the array from index 1 to 3 using the
sliceArray()
method and store the result in the variablesubArray
. - 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]
