How to force developers use only 'yyyy' instead of 'YYYY' in simpleDateFormat?












1















Since YYYY is week based year and yyyy is yearly, we need any of these:
1. Force developers to never enter 'YYYY' in simpleDateFormat("YYYY") in code OR
2. Write a test case, which will scan the code and inform user in case they used simpleDateFormat with YYYY to correct it.



We are trying Sonarqube custom rules. And scan the project during build.
Need to know if anyother way we can force it during development or during git commit to bitbucket.



SimpleDateFormat sdf=new SimpleDateFormat("MM/dd/YYYY");



We need in such scenario or any scenario where developer uses "YYYY" to block it or convert it to "yyyy"

    Semi-related: You should also get your developers not to use SimpleDateFormat, as this is legacy. You should be using the java.time package instead.

  • If you care about enforcing yyyy over YYYY, why not enforce dd over DD, and MM over mm? Instead, why not teach your developers to write good code.
