Pro Free
Learn Java is completely free to use and will always be free.
Pro Simple interface
The interface is very straight-forward and well layed out.
Pro Human review and feedback
Rather than merely test for code correctness, Exercism uses peer review to improve general programming techniques. Users are encouraged to comment on others' solutions, and refine their own based on feedback.
Pro Practice with production tools
Unlike many code practice websites, Exercism requires the user to develop and test entirely offline, submitting only the finished code. This promotes familiarity with essential tools and workflow, not just the bare language.
Cons
Con Editor not easily adjustable
The code editor at the bottom of the page, where you follow along with the tutorial, is fairly small and provides no way to adjust the size.
Con Custom commandline client
Exercism requires using a CLI utility to fetch and submit exercises. This is inconvenient compared to web-only alternatives, and poses an additional barrier to entry for some users.
