Get the hashmap highest value

Hey!I am making a bukkit minigame plugin.So i am stucked here:

When a player kills other player, must add a point to the Hashmap <String, Integer>.
And when some player arrives 10 kills, the game ends.Please, help.

 

Code:Java

 
int highestNumber = 0;
String highestPlayer = null;
 
for (String player : hashMap.keySet()) {
if(hashMap.get(player) > highestNumber) 
highestNumber = hashMap.get(player);
highestPlayer = player;
}
 

 

Okay, but when the player kills other player must be added to the hashmap in this way?
hashMap.put(killer.getName(), +1) ?

Anyone? Please respond.

Get their current score and add one
Score++
Score = Score + 1

 

Code example?

What have you tried? It seems you don't have an understanding of Java, so maybe try learning some of that first.

FisheyLP Huge spoonfeed .

 

tryfme To add one to their HashMap value, get their current kills value, add 1 to it, then put that new value in the map.
During that process you could add a check to see if the new value is 10 (or old value is 9) and if so, end the game.

 

How must be look like?

 

tryfme As above, please learn Java first. Nobody should be willing to provide the code for you, that's entirely your job.

 

tryfme However it's correct java and does what it should
This shouldn't be to hard to figure out if you know what you're doing
