Solved Getting Entities around a dropped item

I'm creating a plugin that when you drop an item using q (obviously) it checks the dropped items location and if it lands near an entity it reports the entities name else it returns with no entities near the item. however I everytime I send the message that there are no entities near the item is sends the message for every entity in the server which makes sense considering my code but I don't know how to get around it so it only sends the message once!

Code:

    @EventHandler
     public void onThrow(PlayerDropItemEvent event) {
         if (event.getItemDrop().getItemStack().getItemMeta().getDisplayName().equalsIgnoreCase("Radar")) {
             event.getPlayer().sendMessage("you threw a detector.");
             List<Entity> entities = new ArrayList<Entity>();
             Location iloc = event.getItemDrop().getLocation();
             for (World world : Bukkit.getServer().getWorlds()) {
                 for (Entity ent : world.getEntities()) {
                     if (!(ent instanceof Player)) {
                             if (ent.getNearbyEntities(5, 5, 5).equals(iloc)) {
                             event.getPlayer().sendMessage(ent.getName().toString());
                             } else {
                                 event.getPlayer().sendMessage("no entities near the radar.");
                         }
                     }
                 }
             }
         }
     }

Any suggestions?

Solved using the following code:

Code:

            for (World world : Bukkit.getServer().getWorlds()) {
                  for (Entity ent : world.getNearbyEntities(event.getItemDrop().getLocation(), 5, 5, 5)) {
                      if (!(ent instanceof Player)) {                          
                              event.getPlayer().sendMessage(ent.getName().toString());
                              } else {
                                  event.getPlayer().sendMessage("Miss");
                              }

Why do this through all of the worlds? Just getLocation().getWorld().getNearby...
Makes it faster, also I recommend checking if getNearbyEntities size is 0 then print miss otherwise do this.

List<entity> nearby = getLocation.getWorld.getNearbyEntities getLocation, 5, 5, 5;
if nearby size is > than 0
for Entity ent : nearby
...
end for
else say Miss
