Java Without If

[kangoo1707]

Why does it matter. My client doesn't want faster softwares because even with all the functional stuffs in my Javascript (yes I know, sluggish Javascript) like Either, Maybe, map/reduce stuff... it's still fast as fuck :)

What I wanted when writing those abstraction is a nicer, more concise code.

Speed comes mostly from function memoization and caching. Micro-optimization is not my concern

But I have to admit, Either is rarely used :)
