PermissionsEx Group Create

Hello, I Have A Problem. I Tried To Make A Little Script Where I Can Easily Create Pex Groups With A Short Command The Script:

Code:

package de.Groupcreate.commands;

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

import de.Createpexgroup.main.Main;

public class CMD_creategroup implements CommandExecutor {

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
     
        Player Player = (Player)sender;
     
        if (cmd.getName().equalsIgnoreCase("creategroup")) {
            if (args.length == 0) {
                if (Player.hasPermission("Groupcreate.creategroup")) {
                    Player.sendMessage(Main.prefix + "Usage: /creategroup (Groupname)");
                    Player.playSound(Player.getLocation(), Sound.ANVIL_USE, 3, 1);
                } else {
                    Player.sendMessage(Main.noPerms);
                    Player.playSound(Player.getLocation(), Sound.BLAZE_DEATH, 3, 1);
                }
            } if (args.length == 1) {
                if (Player.hasPermission("Groupcreate.creategroup")) {
                    Player.sendMessage(Main.prefix + "Creating Group...");
                    Player.performCommand("pex group" + args[1] + "create");
                    Player.sendMessage(Main.prefix + "§aSUCCESS!");
                    Player.playSound(Player.getLocation(), Sound.LEVEL_UP, 3, 1);
                }
            } if (args.length > 1) {
                Player.sendMessage(Main.error);
            }
        }
     
        return false;
    }
 
}

But Always When I Run The Command This Happens:

If You Could Help Me That Would Be Great

@Hectiq

1. All variables should start with a lower case letter. "Player" should be "player"
2. The sender can be a player, but it can also be the console, a command block, or any other entity that can send commands. Do an instanceof check before you cast sender to a player.
3. Main problem: Arrays start at 0. To get the first object in the args array (the group name), use args[0]

 

Well, I Tried The Main Problem Still The Same.
Also I Tried 2 Still The Same.
But Ill Test 1 Now
