Plugin doesn't register events.

Hi. this code is not working for some reason. The onEnable() thing works, but the EventHandler doesn't register events. I also tried PlayerMoveEvent and PlayerToggleSneakEvent, but both didn't output any message. Also, I tried to add a command, but it reads: 'Unknown command. Type "/help" for help.'

Code:

package fPlugin;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.player.PlayerDropItemEvent;
import org.bukkit.plugin.java.JavaPlugin;
import org.bukkit.ChatColor;
public class fPlugin extends JavaPlugin {
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if (cmd.getName().equalsIgnoreCase("test") && sender instanceof Player) {
            Player player = (Player) sender;
            player.sendMessage(ChatColor.GOLD +"you tested succesfully!");
            return true;
        }
        return false;
    }
    @EventHandler
    public void onDrop(PlayerDropItemEvent event) {
        Player player = event.getPlayer();
        event.setCancelled(true);
        player.sendMessage("Don't drop stuff.");
    }
    @Override
    public void onEnable() {
        getLogger().info("Plugin Enabled!");
    }
    @Override
    public void onDisable() {
        getLogger().info("Plugin Disabled!");
    }
}

Thanks in advance.

 

I hate it when my comment is under Moderator Review because no-one is going to read it. BESIDES, how do I register the event in onEnable?
getServer().getPluginManager().registerEvents(this, this);
What should "this" and "this" be?

 

put this inside onEnable()

Code:

Bukkit.getPluginManager().registerEvents(this, this);

 

@NoFontNL you should also implement CommandExecutor and Listener. And you have to register the command as well as the event as timtower said

 

oh okay
but he still has to implement listener
