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

split on a String could do the trick:

val ipaddr: Array[Byte] = 
  "192.168.1.1".split('.').map(_.toInt).map(_.toByte)    

Breaking this down we have

"192.168.1.1"
  .split('.')    // Array[String]("192", "168", "1", "1")
  .map(_.toInt)  // Array[Int](192, 168, 1, 1)
  .map(_.toByte) // Array[Byte](-64, -88, 1, 1)
