Need help with HashMaps

Hello!

I recently made a post about players and variables and how I should store them and I was told HashMaps were the way to go. Sadly, I don't really know how to use HashMaps with Players. For example, how would I make a HashMap that stores player stats(levels & xp) so every player has their own stats? Thanks for the help!

@timtower how would I then put stuff in for each player?

HashMaps aren't too difficult, you can create one by using

Code:

HashMap<UUID,OtherClass> map = new HashMap<UUID,OtherClass>();

Then simply add things to it:

Code:

map.put(player.getUniqueId(), object_of_other_class);

To get the object back:

Code:

OtherClass object_of_other_class = map.get(player.getUniqueId());

Check out the HashMap docs to see all the methods you can use on them:
