Convert Byte Array to String in Kotlin

In this tutorial, you shall learn how to convert a given byte array to a string in Kotlin, using String() constructor, with examples.

Kotlin – Convert Byte Array to String

To convert a byte array to string in Kotlin, use String() constructor. String() constructor can take a Byte Array as argument and return a new string formed with the bytes in the given array.

Syntax

The syntax to call String() constructor with Byte Array bytes passed as argument is

String(bytes)

Examples

1. Create a string from given byte array

In the following example, we take an array of bytes, and convert this byte array to string using String().

Main.kt

fun main() {
    val bytes = byteArrayOf(97, 98, 99, 65, 66, 67)
    val str = String(bytes)
    println(str)
}

Output

abcABC

Conclusion

In this Kotlin Tutorial, we learned how to convert a Byte Array to a String using String() constructor, with examples.
