Plugin issues

HI, so I have a question: Can I make a plugin work in a specific world only ? if its possible how can I make it ?
Also, i'm trying to code a plugin that will spawn a rabbit pet when a plyer throw a normal egg.
So far I've done this:

Spoiler: PlayerEggThrowEvent

Code (Text):

package me.mariozgr8.events;

import org.bukkit.Location;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.*;

public class EggThrowPlayer implements Listener {

    public EggThrowPlayer(EventsHandler plugin) {
        plugin.getServer().getPluginManager().registerEvents(this, plugin);}
   
    @EventHandler
    public void OnPlayerThrow(PlayerEggThrowEvent e){
        Player p = e.getPlayer();
        Location loc = p.getLocation();
        loc.setX(loc.getX() + 1);
        if(!(p.hasPermission("events.spawning.rabbit"))){}
        if(p.hasPermission("events.spawning.rabbit")){
            //i want to make it here so that a rabbit spawn at the location loc when the player throw the egg.
        }
       
    }
}

But I don't know how to spawn a rabbit at the location loc. Can anyone help me please ?

 

Thanks for your help guys but I can't figure out how to write it I want to spawn a rabbit at the location loc what should o write ?

EDIT: I didn't see the messaged thanks

 

When I typed this I got : The method getWorld(String) in the type Server is not applicable for the arguments (World). How can I fix this ?

 

Thanks guys for your help
