 <!--
  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/java/technologies/javase/codeconventions-contents.html
    - the Javadoc guidelines at
      https://www.oracle.com/technical-resources/articles/java/javadoc-tool.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.
  To suppress certain violations please review suppression filters.
  Finally, it is worth reading the documentation.
