What's wrong!?!?

I'm making a plugin where it does not let you have enchanted swords with sharpness. If you have a sharpness enchanted sword it will remove your sword. I made this code.

Code:java

  @EventHandler
  public void onInteractEvent(PlayerInteractEvent e)
  {
        Player player = e.getPlayer();
        ItemStack DA = new ItemStack(Material.DIAMOND_SWORD, 1);
        if (player.getInventory().contains(DA)){
            if (DA.containsEnchantment(Enchantment.DAMAGE_ALL)){
      player.getInventory().remove(DA);
        }
      }
    }

Though when I try it it doesn't work. I have also tried adding sharpness into the itemstack. Doesn anybody know how to fix this?

 

Did you register the event in your main calss??

 

Did you register the event in the Main class?

 

AlexHH251997 Of course.

 

Have you implemented Listener?
What is the error you are getting?
