Null pointer

Im getting a null pointer on my plugin error:http://dpaste.com/04BYKNJ code: http://dpaste.com/0K8BBH7

 

You have Player player = null. Thats your issue because null pointer means somethings null.
Change to Player p = (Player) sender;

Or instead of initializing your Inventory object "i" outside of the if statement, do so after you assign a value to player that isn't null.

 

If I do that all the "player" then error out

 

Change to Player player = (Player) sender;

 

THANK YOU SO MUCH

You need to make sure to check that sender is instance of Player as well.

 

Okay so heres my code,How would I make it say "you have that already" if they have the book when they type the command
