I must have missed something obvious, but how do
you create a scala-tuple in Java.

I have a scala interface that is implemented in java (for now)
and includes the return of a tuple, but how do I implement it?

    Use the class scala.Tuple1, scala.Tuple2, …, scala.Tuple22.

    http://codemonkeyism.com/tuples-scala-goodness/ explains it well:

    What are tuples? Tuples are containers for values. In Scala you create a Tuple with:

    scala> val t = (1,2)
t: (Int, Int) = (1,2)

    which is syntactic sugar for

    scala> val t = new Tuple2(1,2)
t: (Int, Int) = (1,2)

    as Tuples are plain classes in the Scala library. Tuples are of type Tuple1, Tuple2, Tuple3 and so on.
