How Can I Convert A Bytearray Into An String And Reverse In Kotlin?

I'm trying to convert a String to a ByteArray, and convert the ByteArray to a String in Kotlin. My program was crashing, so I decided to debug a little, and my surprise was that wh

Solution 1:

When you print out a ByteArray just using toString(), you are effectively getting its object ID (it's a bit more complicated, but that definition will work for now), rather than the contents of the ByteArray itself.

Solution 1

Pass a Charset as an argument to toString():

val bytes = "Hello!".toByteArray()
val string = bytes.toString(Charset.defaultCharset())

println(string) // Prints: "Hello!"

Solution 2

Pass the ByteArray as an argument to the String constructor:

val bytes = "Hello!".toByteArray()
val string = String(bytes)

println(string) // Prints: "Hello!"

Solution 2:

On each encoding the result changes so if you specify the encoding you would not lose any data, you can do that by using Charset

vals="this is an example"valb= s.toByteArray(Charset.defaultCharset())
 println(b)
 valss= String(b, Charset.defaultCharset())
 println(ss)
