Solved Point rankings for players

I have a question, would like to know how I could do so that when I do /ranking, it gives me the rankings of the players say that:

Player 1 : 20 points
Player 2 : 10 points
Player 3 : 45 points


I would like it to display like this :

----------------=RANKING=-------------------
Player 2 - 10 points
Player 1 - 20 points
Player 3 - 45 points
---------------------------------------------------

How can i do that

 

@timtower In a HashMap like:

HashMap<Player, Integer> = new HashMap<>();

 

@timtower , 1er i don't know how to find the hightest value, 2e treemap ?

 

@ScopeTowel This answer might help you.

 

Can you give me an example ?

@timtower Because I know how to display them but not to sort

Why not store the UUID instead? Unless I remember wrong, it's not recommended to store Player objects.

 

@timtower
Yes I know, but I put that, because its with an api, the real HashMap is :

HashMap<Faction, Integer>

But i need an exemple, because i don't know how to found the highest value with a loop
