Sometimes we require to release a specific port from the system. This is to find out how to kill the process using port 8080.

I am trying to run my tomcat on port 8080. But I received the error "Web server failed to start. Port 8080 was already in use." Also mentioned the Action as "Identify and stop the process that's listening on port 8080 or configure this application to listen on another port." Please help with how to do it in macOS?
