Allowing players to use commands in certain areas

So I am coding a kitPVP server. I want it so that when a player is outside of spawn they can't use /kit.

Here is the code:

KitCommand:

Code:

package skits.commands;

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

import skits.util.Util;

public class KitCommand implements CommandExecutor {
    @Override
    public boolean onCommand(CommandSender  sender, Command cmd, String label, String[] args) {
        if(!(sender instanceof Player)) {
            Player player = (Player)sender;
            if(!(Util.canKit(player))) {
            return false;
            }  
        }
       
       
        Player player = (Player)sender;
        if(args.length >=1) {
            if(Util.kits.contains(args[0].toLowerCase())) { 
                Util.kitPlayer(player, args[0]);   
                player.sendMessage(ChatColor.BLUE + "KitPVP> " + ChatColor.GRAY + "You have selected the '" + args[0] + "' kit!");
                return true;
            }  
            if(args.length >=0) {   
                    player.sendMessage(ChatColor.BLUE + "KitPVP> " + ChatColor.GRAY + "The kit '" + args[0] + "' doesn't exsist!");
                    player.sendMessage(ChatColor.BLUE + "KitPVP> " + ChatColor.GRAY + "Here is a list of kits that you may use: Archer, PVP, Tank, Demon.");
                    return false;
        }
        player.sendMessage(ChatColor.BLUE + "KitPVP> " + ChatColor.GRAY + "The kit '" + args[0] + "' does not exist!");
        player.sendMessage(ChatColor.BLUE + "KitPVP> " + ChatColor.GRAY + "Here is a list of kits that you may use: Archer, PVP, Tank, Demon.");
        return false; 
            }
        return false;   
    
        }
    }

canKit:

Code:

public static boolean isCloseToSpawn(Location loc) {
        return isCloseToSpawn(loc, 5);

    }
   
    public static boolean  isCloseToSpawn(Location loc, int radius) {
        if(loc == null) {
            return false;
        }
        int x = Math.abs(loc.getBlockX() - spawn.getBlockX());  
        int z = Math.abs(loc.getBlockZ() - spawn.getBlockZ()); 
       
        return (x < radius) && (z < radius);
    } 

   
    public static boolean canKit(Player p) {
       
        if(!(p.getLocation().equals(Util.isCloseToSpawn(Util.spawn, 5)))); {
            return false;
        }
    }
