Beginners question about the ports of Tomcat and http

[strange river]

Per default, Tomcat starts like this:
Tomcat started on port(s): 8080 (http)
As far as I know, http always has port 80
So how can Tomcat have port 8080 and communicate via http at the same time?
Is it possible that a communication involves TWO ports? First it goes to port 80 and then from there it goes to 8080?

you misunderstand how ports work

the standard http port is merely a suggestion

not providing any port in a compliant url parser will assume port 80 for http and port 443 for https

http://abc.com implies port 80
http://abc.com:1234 specifies port 1234

you can specify ports explicitly by adding a : after the host
