1 Example

In this example,

We create a list named list containing the characters 'a', 'b', 'c'.
We call the toCharArray() function on list, which converts the list to a Char array.
The resulting Char array is stored in result.
Finally, we print the content of result to standard output using the contentToString() function.

Kotlin Program

fun main(args: Array<String>) {
    val list = listOf('a', 'b', 'c');
    val result = list.toCharArray();
    println(result.contentToString());
}

Output

[a, b, c]
