      Description

      Use the entrySet() iterator when retrieving values from a Map, instead of retrieving values from the Map while iterating over the Map keys using keySet(). Performance of this is better than calling Map.get(key) for each entry while iterating also.

      Example:

      bad performance:

      for (String name : map.keySet()) {
       String value = map.getValue(name);
      ...
      }
      

       

      good performance:

       

      for (Map.Entry<String, String> entry : map.entrySet()) {
       String value = entry.getValue();
      ...
      }
