call the profession in the main?

Well, you already have the type declaration PlayerOne player; so just call player.getProfessions() and use the array.

call the inventory in the main?

Just the same: player.getInventory().

However, note that your design is somewhat flawed (although since you're a beginner don't bother too much). The class name PlayerOne indicates any other player (e.g. PlayerTwo) would be different, but that's probably not the case. Also, AllPlayers doesn't actually indicate a class, but it looks more like a collection.

You might think about changing your class names, e.g. assuming AllPlayers will be used for NPCs as well, you could name it Character while the class for players is called Player. Doing this you could have multiple players if needed: Player playerOne, Player playerTwo etc.

this in that position references the BukkitRunnable(), not your Main class. You can fix this by passing a reference to your Plugin like so

Try this:

Let's focus on the stack trace first. If you look carefully you can see which file and line the problem originated in:

Your issue is that you have misunderstood how the add() method works with locations. You are adding the provided doubles to the current location and so you do not need to specify the coordinate again.

So to add 1 to the X coordinate, you would do so like

Well you don't need the loop at all. You can use a IN operator to get all medicinedatabases in a single query like so:

It is written as a comment in the code for method testboatStock() in your question. Namely...

Hint: parkBoatAt is not just a accessor, and not just a mutator

The requirements are not completely clear to me but I presume that method parkBoat should check whether the element in array boats at index slipNumber is null. If it is, then put the boat into the array at that index and return the boat, thus indicating that the boat was successfully parked. Otherwise, i.e. if the array index already contains a boat, that means the spot is taken and you can't park two boats in the same spot.

Your code seems solid and at first sight I don't see what could possibly be wrong with it (Unless you just didn't register the event). Though there is a flaw. You should probably check if event.getDamager() is an instance of Player before casting it. I also recommend using ageableEntity.damage(damage, player) so that the game processes it as if the player actually killed it, and it doesn't just suddenly die.

I've used your own code and made some changes to it, and added comments which should explain what everything is there for. This is just an alternative assuming the code you have really didn't work.

Since the ajax call is an async operation, the loop variable i would have changed by the time the success method gets called. There is no guarantee that the i would have reached the end. You would need to wrap the variables, in a closure so that it success methods gets the correct item. Sample code not tested.
