How to Declare a String Array in Kotlin ?

Answer

To declare a string array in Kotlin, you can use the arrayOf function or initialize an array of strings.

✐ Examples

1 Declare a String Array using arrayOf Function

In this example,

We use the arrayOf function to declare a string array named stringArray with specific string values.
The arrayOf function takes string values as arguments and creates an array with those values.
Finally, we print the string array to standard output.

Kotlin Program

fun main(args: Array<String>) {
    val stringArray = arrayOf("apple", "banana", "orange", "grape", "pineapple")
    println("String array: ${stringArray.joinToString()}")
}

Output

String array: apple, banana, orange, grape, pineapple

2 Declare a String Array using Array Initialization

In this example,

We declare a string array named stringArray using the Array constructor with the desired size.
We assign string values to each element of the array using array indexing.
Finally, we print the string array to standard output.

Kotlin Program

fun main(args: Array<String>) {
    val stringArray = Array<String>(5) { "" }
    stringArray[0] = "apple"
    stringArray[1] = "banana"
    stringArray[2] = "orange"
    stringArray[3] = "grape"
    stringArray[4] = "pineapple"
    println("String array: ${stringArray.joinToString()}")
}

Output

String array: apple, banana, orange, grape, pineapple
