What is the differences between Int and Integer in Scala?

Question

I was working with a variable that I had declared as an Integer and discovered that > is not a member of Integer. Here\'s a simple example:

scala> i

Answer 1

Integer gets imported from java.lang.Integer and is only for compatibility with Java. Since it is a Java class, of course it can't have a method called "<". EDIT: You can mitigate this problem by declaring an implicit conversion from Integer to Int.

 implicit def toInt(in:Integer) = in.intValue()

You'll still get deprecation warning though.
