  Checkstyle configuration that checks the sun coding conventions from:

    - the Java Language Specification at
      https://docs.oracle.com/javase/specs/jls/se11/html/index.html

    - the Sun Code Conventions at https://www.oracle.com/technetwork/java/codeconvtoc-136057.html

    - the Javadoc guidelines at
      https://www.oracle.com/technetwork/java/javase/documentation/index-137868.html

    - the JDK Api documentation https://docs.oracle.com/en/java/javase/11/

    - some best practices

  Checkstyle is very configurable. Be sure to read the documentation at
  https://checkstyle.org (or in your downloaded distribution).

  Most Checks are configurable, be sure to consult the documentation.

  To completely disable a check, just comment it out or delete it from the file.

  Finally, it is worth reading the documentation.
