Byte declaration in Kotlin makes compile-time error "Integer literal does not match expected Byte type"
As you can see, another question at 0xFF0000FF Integer literal does not match the expected kotlin.Int type
I declare the value 0xFF as Byte
val b:Byte = 0xFF
Getting Integer literal does not match expected Byte type Compilation error
Since I have the key to the kotlin.Byte
signed byte
How to declare byte in Kotlin with 0x00
- 0xFF
unsigned byte like.net Byte b = 0xFF
?

If you need a compiler to test and answer:

Kotlin does not automatically convert between number types.
If you do val b:Byte = 0xFF.toByte()
, then it compiles and outputs a byte with a value -1
.
If you want to store the unsigned byte value, you need to store it as Char
, but you will need to convert it to another type in order to print it as a number:
val b = 0xFF.toChar()
println(b.toInt())
