How to convert an Array[Byte] to an Array[Int] in scala/spark?

I have an Array[Byte] and I want to convert it to an Array[Int]:

for example,

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

val y : Array[Int] = Array(192, 168, 1, 9)

How can I convert x to y ?

I tried this and it works:

val y = x.map(_.toInt & 0xff).deep

You can use simply map

val y:Array[Int] = x.map(_.toInt)
