Answer 1

I think the problem you're seeing has has to do boxing/unboxing of value types and the use of the Java class Integer.

I think the answer is here: Boxing and unboxing in Scala. There is no implict unboxing in Scala. You've defined i as the Java class Integer but in the i > 3, the 3 is being treated and an int.
