I am a beginner in Kotlin and I was trying to append bytes at the end of a ByteArray. How can I do that ?
Here is one way I tried. Does it look right?
var someByteArray = byteArrayOf(*payload, 0x01.toByte())
where payload is a ByteArray
Your help is much appreciated
ByteArray overloads the plus operator, so you can just add to the previous value directly, or assign to a new array. For example:
val startArray = byteArrayOf(0x1, 0x2, 0x3)
val newArray = startArray + 0x4.toByte()
Or if you want to keep the mutable var, you can just plus-assign it:
var array = byteArrayOf(0x1, 0x2, 0x3)
array += 0x4.toByte()
