Update on first MC Plugin ever :)

Ok, Here's what I got so far for my plugin
File Name; DisguiseCraftNoDrop.java

package me.funnygatt.DisguiseCraftNoDrop;

import java.util.ArrayList;
import java.util.logging.Logger;

import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;

public class DisguiseCraftNoDrop extends JavaPlugin{

    public static DisguiseCraftNoDrop plugin;
    public final Logger log = Logger.getLogger("Minecraft");
    public boolean enabled = false;
    public final PlayerListener pl =new PlayerListener(this);
    public final ArrayList<Player> DisguiseCraftNoDropUsers = new ArrayLisy<Player>();
    public String lol = "[DCNP] ";

    @Override
    public void onEnable() {
        log.info(lol + "is now enabled. This plugin was created by Funnygatt");

        PluginManager pm = getServer().getPluginManager();
        pm.registerEvents(pl, this);
    }

    @Override
    public void onDisable() {
        log.info(lol + "is now DISABLED. Thanks for using this Plugin");
    }

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
        if(commandLabel.equalsIgnoreCase(DisguiseCraftNoDrop)) {
            if(arg.length==0) {
                if(!enabled) {
                    enabled = true;
                    ((player) sender).sendMessage(ChatColor.RED + lol + "is now enabled, Disguised players wont drop their inventory");
                }
                else {
                    enabled = false;
                    ((player) sender).sendMessage(ChatColor.RED + lol + "is now DISABLED, Why would you do that?");
                }
            }
        }
        return false;
    }

}

And here is my PlayerListener.java

package me.funnygatt.DisguiseCraftNoDrop;

import java.util.logging.Logger;

import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerInteractEvent;

public class PlayerListener implements Listener {

    public static DisguiseCraftNoDrop plugin;
    public Logger log = Logger.getLogger("Minecraft");

    public PlayerListener(DisguiseCraftNoDrop instance) {
        plugin = instance;
    }

    @EventHandler
    public void onPlayerDeath(PlayerInteractEvent event) {
        if(plugin.enabled) {
    }

}

---------
Am I going good right now?
