How to declare a byte array in Scala?

Question

In Scala, I can declare a byte array this way

val ipaddr: Array[Byte] = Array(192.toByte, 168.toByte, 1.toByte, 9.toByte)

This is too verbo

Answer 1

You can use implicit

    implicit def int2byte(int: Int) = {
      int.toByte
    }

And that will convert all Int values in scope in places where byte is required.
