 ## Policy Descriptions
 
-### Prefer instance methods [[1](https://github.com/exercism/xjava/issues/177#issuecomment-261291741)]
+### Prefer instance methods
 
-Most (all?) exercises should be implemented in the form of instance methods since they contain "domain logic" and we (Exercism) want to encourage exemplary software.

-- Exercises 1-10: provide stubs for all required methods.
-- Exercises 11-20: provide stubs for all methods required by the first test; comment-out the bodies of any tests that require non-stubbed methods.
-- Exercises 21+: provide no stubs, but mention any "interesting" interface aspects in the HINT.md file (which gets merged into the README.md for the exercise).

-All but the first test in an exercise test suite should be annotated `@Ignore`.

+### Ignore noninitial tests
 
-The first exercise in the track whose test suite mandates multiple solution files should be accompanied by a HINT.md file reminding the practitioner that the CLI supports multiple file submissions.

-Aim to keep 10-20 small and straightforward issues open at eny given time. Identify any such issues by applying the "Good first patch" label.

-The Installing Java instructions should seek to minimize the number of steps and the number of concepts a new-to-the-track practitioner needs to learn to get to coding.
