In this tutorial, you shall learn how to print the contents of a given array in a single line in Kotlin, using For loop, with examples.

Kotlin – Print array in single line

To print an Array in single line in Kotlin, use For Loop. Inside For Loop, write print statement to print the element. If the body of For Loop has only one statement, then it can written right after for-in.

Refer Kotlin For Loop tutorial.

Syntax

The syntax to print elements of array arr in a single line is

</>
Copy
for (x in arr) print("$x ")

Examples

1. Print the given array to output in a single line with space as separator

In the following example, we take an array of integers, and print them to standard output in a single line with space as separator between the elements.

Main.kt

</>
Copy
fun main(args: Array<String>) {
    val arr = arrayOf(2, 4, 6, 8, 10, 12)
    for (x in arr) print("$x ")
}

Output

2 4 6 8 10 12

2. Print the given array of strings in a single line

In the following example, we take an array of strings, and print them to standard output in a single line.

Main.kt

</>
Copy
fun main(args: Array<String>) {
    val arr = arrayOf("apple", "banana", "cherry")
    for (x in arr) print("$x ")
}

Output

apple banana cherry
