Make a player able to gain more playtime?

I have this code:

So when a player joins, they get added to a list which lets them play for 500 minutes. I want to know how I can make it so :
If they kill a mob, they get more time.
Thanks!
(If you have a better way, let me know)

Ahhh what are you doing! Dont put actual player instances in maps or lists. Instead store their names.

But to answer your question, what I would do is make a HashMap instead of an Arraylist. That way you can store the times of players with the actual players themselves.

Example:
HashMap<String, Integer> playerTimes = new HashMap<String, Integer>();

Then you can have a setter method and when it gets to zero kick the player. Or you can even try out MetaData for this. Not sure but from what it sounds like you can use it for players as well.

 

Tooner101 Please give me an example? I am kind of having an issue understanding.

What happened to creepers code... I was gonna say that you don't need to remove a key from a hashmap, then put it back. .put() will replace the key if its already in the HashMap
