    • count

      public static <T> void count(T key, Map<T,Integer> counter)
      If the key is not in the map, it will be added with the value of 1. In any case, the value will be incremented by i.
      Type Parameters:
      T - Any kind of object. Type of the key in the counter map.
      Parameters:
      key - A key in the counter map or a value that can be used as a key of that map
      counter - A map which uses any kind of object as key and integer as value. Essentially counts the occurrences of the keys.
