Problem connecting to bukkit listener

I am new to coding and i was following a tutorial to make a scoreboard to count my steps i take. I put it on my server and i got an error saying "java.lang.ClassCastException: me.storm2.info.main cannot be cast to org.bukkit.event.Listener" heres the full error and my main class. I am new to coding so im not very good at debugging and trying to find the problem so i thought anyone that could help find this problem would help me gain more experience with it.

Code:

[18:26:19 ERROR]: Error occurred while enabling Scoreboard v1.0 (Is it up to date?)

Remove the Listener cast at line 27 and have your class implement Listener:

Code:java

public class main extends JavaPlugin implements Listener
