code: public static <K, V> ArrayMap<K, V> create(int initialCapacity) {
      ArrayMap<K, V> result = create();
      result.ensureCapacity(initialCapacity);
      return result;
    }
docs: Returns a new instance of an array map of the given initial capacity. For example: {@code
  ArrayMap<String, String> map = ArrayMap.create(8);}.
