Kotlin: Print array elements

In my previous post, I explained what is an array and how to define it in kotlin. In this post, I am going to show,how to print elements of an array.

Print elements of array using for loop

ArrayUtil.kt

fun main(args: Array<String>) {

 var arr: Array<Int> = arrayOf(1, 2, 3, 4)

 for (ele in arr) {
  println(ele)
 }
}

Output

1
2
3
4

Print array elements using 'Arrays.toString' method

ArrayUtil.kt

import java.util.Arrays

fun main(args: Array<String>) {

 var arr: Array<Int> = arrayOf(1, 2, 3, 4)

 println(Arrays.toString(arr))
}

Output

[1, 2, 3, 4]

Print array elements using array.indices

ArrayUtil.kt

fun main(args: Array<String>) {

 var arr: Array<Int> = arrayOf(2, 3, 5, 7)

 for (index in arr.indices) {
  println(arr[index])
 }
}

Output

2
3
5
7

Print array elements using array.withIndex

ArrayUtil.kt

fun main(args: Array<String>) {

 var arr: Array<Int> = arrayOf(2, 3, 5, 7)

 for ((index, value) in arr.withIndex()) {
  println("index : $index, value : $value")
 }
}

Output

index : 0, value : 2
index : 1, value : 3
index : 2, value : 5
index : 3, value : 7

Print array elements using while loop

ArrayUtil.kt

fun main(args: Array<String>) {

 var arr: Array<Int> = arrayOf(2, 3, 5, 7)

 var sizeOfTheArray = arr.size;
 
 var index : Int = 0;
 
 while(index < sizeOfTheArray){
  println("index : $index, value : ${arr[index]}")
  index++
 }
}

Output

index : 0, value : 2
index : 1, value : 3
index : 2, value : 5
index : 3, value : 7
