Spawn Egg troubles

What is the simplest way to spawn the entity that a spawn egg would spawn?

For example, spawning a zombie entity by examining a zombie egg.

I've been playing around with it but the only way I have found that is working is clunky, deprecated, and seems more like a work around than a solution.

Code:

    @SuppressWarnings("deprecation")
    @EventHandler
    public void chestClick(PlayerInteractEvent e) {
        if (e.getAction() == Action.RIGHT_CLICK_BLOCK) {
            Block b = e.getClickedBlock();
            Player player = e.getPlayer();
            if (b.getType() == Material.CHEST) {
                Chest c = (Chest) b.getState();
                if(c.getInventory().contains(Material.MONSTER_EGG)) {
                    HashMap<Integer, ? extends ItemStack> eggMap = c.getInventory().all(Material.MONSTER_EGG);
                    Set<Integer> set = new HashSet<Integer>();
                    set.addAll(eggMap.keySet());
                    for (Integer i : set) {
                        ItemStack it = eggMap.remove(i);
                        log.info("The ItemTypeId : " + it.getData().getItemTypeId());
                        log.info("The ItemTypeId : " + it.getData().toString());
                        String s = it.getData().toString();
                        s = s.substring(10);
                        s = s.substring(0, (s.length()-1));
                        log.info("String: " + s);
                        b.getWorld().spawnEntity(b.getLocation(), EntityType.fromName(s));
                        c.getInventory().removeItem(it);
                    }
                }
            }
        }
    }

 

Take a look at the docs:

Using this method you can get the type that will be spawn instead of String maniplulations etc which arent all that secure.
Also, what are you trying to do here:

 

Thank you so much. I knew there had to be an easier way that wasn't soooo terrible. The entire time I was doing the string manipulation I knew it was a horrible idea I just hadn't found an easier way and just wanted to work out further details like where to spawn them, etc.

I had googled a million different things but I guess I overlooked the old spawn eggs because it refers to them as monster eggs. Thanks again.
