Removing a specific item ID from one's inventory after use

Okay so I'm trying to make a plugin and this is what I have so far, I want the bone to make a lighting and make the anvil sound, and the stick to make an explosion and make the enderman scream sound.

Here's my code:

Code:

    @EventHandler
    public void onPlayerInteract(PlayerInteractEvent event) {
        Player player = event.getPlayer();
        int blockId = player.getItemInHand().getType().getId();
        if(blockId == 280){
            Block block = player.getTargetBlock(null, 10);
            Location location = block.getLocation();
            World world = player.getWorld();
            world.playSound(location,Sound.ENDERMAN_SCREAM, 1, 1);
            world.createExplosion(location, 5);
            blockId 280 delete
        } else if(blockId == 352){
            Block block = player.getTargetBlock(null, 10);
            Location location = block.getLocation();
            World world = player.getWorld();
            world.playSound(location,Sound.ANVIL_LAND, 1, 1);
            world.strikeLightning(location);
        }

I want it so that if I use the stick/bone it removes the stick/bone from my inventory, but if I have 2 sticks/bones it only removes one but keeps the other. I'm pretty new to plugin programming so this might be extremely simple and 'm just too stupid to figure it out.

PHP:

if(player.getInventory().contains(Material.YOUR_MATERIAL)) {
player.getInventory().removeItem(new ItemStack(Material.YOUR_MATERIAL, 1));
}

 

Basically with

Code:java

player.getInventory().clear(player.getInventory().getHeldItemSlot());

and for your case

Code:java

if (player.getItemInHand().getAmount() == 1) {
    player.getInventory().clear(player.getInventory().getHeldItemSlot());
} else {
    player.getItemInHand().setAmount(player.getItemInHand().getAmount()-1);
}

 

Thank you for both of your replies! Both ways worked!
