Bossbar error

Code:

package pearlpvp.main;

import me.confuser.barapi.BarAPI;

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

import pearlpvp.playerjoin.PlayerJoin;

public class main extends JavaPlugin {

    public void onEnable(){
        getLogger().info("PearlPVP has enabled!");
        PluginManager pm = getServer().getPluginManager();
        pm.registerEvents(new PlayerJoin(), this);
        getCommand("bbe").setExecutor(null);
        getCommand("bbd").setExecutor(null);
    }
   
    public void onDisable(){
        getLogger().info("PearlPVP has disabled!");
        }
       
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args){
        Player p = (Player) sender;
        if (label.equalsIgnoreCase("bbe")) {
            p.sendMessage(ChatColor.GOLD + "Bossbar has enabled!");
            BarAPI.setMessage(ChatColor.GOLD + "Welcome on PearlPVP");
                return false;
            }
               
        if(label.equalsIgnoreCase("bbd"))
            p.sendMessage(ChatColor.GOLD + "Bossbar has disabled!");
            if(BarAPI.hasBar((Player)sender)) {
                BarAPI.removeBar((Player) sender);
            }
           
        return false;
    }

}

When i type the command he says Unhandled exception executing command 'bbe' in plugin PearlPVP v1.0
How to fix?

 

@Racingluca2001 The executor is null.

Code:

package pearlpvp.bossbar;

import me.confuser.barapi.BarAPI;

import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;

public class Bossbar implements CommandExecutor {

    @Override
    public boolean onCommand(CommandSender sender, Command command, String label,
            String[] args) {
        if(label.equalsIgnoreCase("enable")){
            Player p = (Player) sender;
            p.sendMessage(ChatColor.GOLD + "Bossbar has enabled!");
            BarAPI.setMessage(ChatColor.GOLD + "Welcome on PearlPVP");
        }
        return false;
       
        if(label.equalsIgnoreCase("disable")){
            p.sendMessage(ChatColor.GOLD + "Bossbar has disabled!");
            if(BarAPI.hasBar((Player)sender)) {
                BarAPI.removeBar((Player) sender);
            }
        }
        return false;
    }   
       
}    

if i type at disable p.sendMessage does p not work

This should be your COMMAND, in your case I assume "bbe" and then you check for args.

So you would do:

Code:

if (label.equalsIgnoreCase("bbe") && args.length > 0) {
  if(args[0].equals("disable") {
  }
  else if(args[0].equals("enable") {
  }
}
