   So, basically what I need to do is check how many times a player interacts with a lever, for example.
   
   So, I have a PlayerInteractEvent, and I want to get the existing value (number of times the player has used a lever before) and add 1 to it.

   Yes a HashMap is good for that.
   Just do
   

   Code:

   HashMap<String, int> counter = new HashMap<String, int>();
    
   String player = event.getPlayer().getName();
   int newValue = counter.get(player)+1;
   counter.put(player, newValue);

   I get "Syntax error on token "int", Dimensions expected after this token" when copy-pasting that code in Eclipse
