Why I Prefer Functional Programming

Meh.

  var colours = coordinates.stream().map(this::computeColour).collect(toList());

  var colours = coordinates.stream().parallel().map(this::computeColour).collect(toList());

Java doesn't do as much (well, anything) to help you make sure the implementation of computeColour is suitable for parallelisation, but that comes with the territory. On the other hand, it will automatically split the stream up appropriately for the number of cores you have.

You have just started that Java isn't as good but since it isn't, it shouldn't be judged so hardly and thus concluded that Java is as good as any (when using softer requirements just for Java)

I also think that explicit threadpool isn't the same thing as implicit one. But that's very minor issue here easily solvable by different api for parallel method

Java's type safety in general is less than Haskell's. That's a separate topic from ease of parallelization in Java and Haskell.
