First Contact with Switch Expressions in Java 12

With Java 12, `switch` is no longer just a statement, but becomes an expression. That means it can have a return value (instead of having to assign or return results) and with a lambda-like syntax that doesn't fall-through (no more `break` ?) and exhaustiveness checks (less `default` ) it is much more readable.
