Doesn't display text when the event is executed

Hi all. I am quite new to plugin development. I'm trying to create a very simple plugin, which should write text to the player when the player enters and display the second text when the right mouse button is pressed. Here is the code:

package spamshit.yadebil;

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.block.Action;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.plugin.java.JavaPlugin;


public final class Yadebil extends JavaPlugin {

@Override
public void onEnable() {
getLogger().info("SpamGovno is working!");}
@Override
public void onDisable() {
getLogger().info("SpamGovno is disabled!");}
@EventHandler
public void onJoin(PlayerJoinEvent event) {
Player player = event.getPlayer();
player.sendMessage(ChatColor.GREEN + "text1");}
@EventHandler
public void onItemClick(PlayerInteractEvent e) {
if(e.getAction() != Action.RIGHT_CLICK_AIR && e.getAction() != Action.RIGHT_CLICK_BLOCK) return;
ItemStack item = e.getItem();
if(item == null) return;
if(item.getType() == Material.DIRT){
e.getPlayer().sendMessage("ты хуесос");
}
}
}

 

@KoT_B_MaMe Your class needs to implement the Listener interface. You also need to register the listener in the onEnable.

 

why is your class final?

 

Thank You!
