I have read check documentation: https://checkstyle.org/checks/xxxxxx/nameofaffectedcheck.html I have downloaded the latest checkstyle from: https://checkstyle.org/cmdline.html#Download_and_Run I have executed the cli and showed it below, as cli describes the problem better than 1,000 words

/var/tmp $ javac YOUR_FILE.java
#[[MAKE SURE THERE IS SUCCESSFUL COMPILATION]]

/var/tmp $ cat config.xml
#[[PLACE YOUR OUTPUT HERE]]

/var/tmp $ cat YOUR_FILE.java
#[[PLACE YOU OUTPUT HERE]]

/var/tmp $ RUN_LOCALE="-Duser.language=en -Duser.country=US"
/var/tmp $ java $RUN_LOCALE -jar checkstyle-X.XX-all.jar -c config.xml YOUR_FILE.java
#[[PLACE YOUR OUTPUT HERE]]

For Windows users, please use type instead of cat and run

set RUN_LOCALE="-Duser.language=en -Duser.country=US"
java %RUN_LOCALE% -jar checkstyle-X.XX-all.jar -c config.xml YOUR_FILE.java

in place of the last 2 commands above.

Describe what you expect in detail.

Still not clear ??? see example - https://checkstyle.org/report_issue.html#How_to_report_a_bug.3F
