When I was coding in Java I used to build Classes just to return multpile values and also sometimes used pass by reference (by means of using Objects). I really missed a permanent solution 😦 Scala has a solution for this- It supports something called “Tuples” which is created with the literal syntax of a comma-separated list of the items inside parentheses like (x1,x2,x3 …). The items in the parantheses may not be related to each other in terms of the type, which means that we can have String’s, Int’s and so on. These literal “groupings” are instantiated as scala.TupleN instances, where the N is the number of items in the tuple. The Scala API defines separate TupleN classes for N between 1 and 22, inclusive. Tuples can be assigned to variables, passed as values or return them from the methods.
