I checked these
For Java Servlet API Version:
Check Web Container Documentation: If you’re deploying your application to a specific web container (like Apache Tomcat, Jetty, or any other), you can refer to its documentation to find out which version of the Servlet API it supports.
Check Servlet API JAR: If you have access to the libraries used in your project, you can locate the Servlet API JAR file and inspect its version. The Servlet API JAR file typically has a name like servlet-api-x.x.jar or javax.servlet-api-x.x.jar. The version can often be found in the file name or in the META-INF/MANIFEST.MF file inside the JAR.
