   this error happens when I print this.
   
   http://prntscr.com/lja012
   
   

   Code:

   System.out.println("x");
                                                   System.out.print(toolinv.get(player.getUniqueId()).getItem(1).getType());

   am I not doing this right?

   @thechrisanator toolinv.get can return null, getItem can return null.

   how do I check if getItem will return null?
   I've figured out if (toolinv.containsKey(player.getUniqueId())), but I'm not sure about getItem
   
   is it just if getitem != null?

   @thechrisanator
   if(...getItem(1) == null){
   // Item is null. Don't do anything with it.
   }
