Randomly enchanting a book

Here's my code. The only issue (to my knowledge) is the itemstack thing. How would I fix it so it forces you to be holding a book? Thanks for the help in advance.

Code:

if (cmd.getName().equalsIgnoreCase("randomenchant")) {
            Player p = (Player) sender;
            if (p.getItemInHand() == new ItemStack(Material.BOOK)) {
                if (p.getExpToLevel() > 9) {
                ItemMeta im = p.getItemInHand().getItemMeta();
                int max = 24;
                int min = 0;
                Random randomNum = new Random();
                int val = min + randomNum.nextInt(max);
                int max2 = 4;
                int min2 = 1;
                Random randomNum2 = new Random();
                int val2 = min2 + randomNum2.nextInt(max);
                im.addEnchant(hm.get(val), val2, true);
                sender.sendMessage(ChatColor.GREEN + "You got: " + hm.get(val).toString() + ". 10 levels have been removed.");
            } else {
                sender.sendMessage(ChatColor.GREEN + "You must have atleast 10 levels to do this!");
            }
            }else {
                sender.sendMessage(ChatColor.RED + "You must be holding a book.");
                sender.sendMessage(p.getItemInHand().toString());
            }
        }

Clarify: The issue is that whatever you hold, it says you must be holding a book.
the sender.sendmessage after "you must be holding a book" is for testing purposes only

 

I think your problem lies with the else { } statements. try:

Code:

else if(p.getExpToLevel() < 10)

instead of just regular else. same concept applies with the other else:

Code:

else if(!p.getItemInHand() == new ItemStack(Material.BOOK))

 

Hey I'm pretty sure you're giving regular enchants to books which will for instance give books actual knockback with a knockback enchant. To give a book the enchant that's only used to enchant other items, you'll have to do the following:

Code:

EnchantmentStorageMeta storedEnchantMeta = (EnchantmentStorageMeta)item.getItemMeta();

Simply add enchants to the storedEnchantMeta instead.
I hope I helped somehow.
