    You could get the keySet() from the Map, and loop through all the values and display the 3 highest ints after the loop is done.

    Having used @2008Choco's example, you would next just need to get the first 3 entries in the LinkedHashMap. You could have some sort of counter variable and a list variable that stores the top 3 players and then begin a for loop going through the "results" LinkedHashMap using #keySet() until you have 3 results. Increment the counter variable and add to your list variable until you have 3. Next, just use the #get() method on the "results" LinkedHashMap to obtain the integer value that corresponds to a player.
