I wrote a something[0] that demonstrates Haskell programs side-by-side with a Java program for a super toy problem. It goes on to explore more complex Haskell abstractions which implement the same simple program using less approachable techniques.

It is primarily meant for helping people understand how the abstractions work, rather than make an argument for when they are good to use, but it might give you enough background to understand the discussion around Haskell abstractions.
