How can I convert CharArray / Array<Char> to a String?

Question

I have a CharArray whose contents are characters like:

val chars = arrayOf('A', 'B', 'C') 

or

val chars = "ABC".toCharArray() 

I want to get the string "ABC" from this. How can I do it?

chars.toString() does not work; it works as if chars was a normal integer array.

Answer 1

you can simply using Array#joinToString:

val result: String = chars.joinToString(""); 

OR convert chars to CharArray:

val result: String = String(chars.toCharArray()); 

OR declaring a primitive CharArray by using charArrayOf:

val chars = charArrayOf('A', 'B', 'C'); val result: String = String(chars);
