Convert an array to a mutable set in Scala?

Question

How does one convert a Scala Array to a mutable.Set?

It's easy to convert to an immutable.Set:

Array(1, 2, 3).toSet

But I can't find an obvious way to convert to a mutable.Set.

Answer 1

scala> val s=scala.collection.mutable.Set()++Array(1,2,3)
s: scala.collection.mutable.Set[Int] = Set(2, 1, 3)
