Next Steps in Scala les are very useful, for example,
if you need to return multiple objects from a method. Whereas in Java
you would often create a JavaBean-like class to hold the multiple return values, in
Scala you can simply return a tuple. And it is simple: <span>to instantiate a new tuple that holds some objects, just place the objects in parentheses, separated by
commas. Once you have a tuple instantiated, you can access its elements individually with a dot, underscore, and the one-based index of the element.
