   public static void main(String[] args) {
      EnumMap<Tutorial, String>  map1 =
              new EnumMap<Tutorial, String> (Tutorial.class);
      EnumMap<Tutorial, String>  map2 =
              new EnumMap<Tutorial, String> (Tutorial.class);

      map1.put(Tutorial.CSS, "1");
      map1.put(Tutorial.Python, "2");
      map1.put(Tutorial.PHP, "3");
      map1.put(Tutorial.Java, "4");

      map2.put(Tutorial.CSS, "1");
      map2.put(Tutorial.Python, "2");
      map2.put(Tutorial.PHP, "3");
      map2.put(Tutorial.Java, "4");

      System.out.println("map1:" + map1);
      System.out.println("map2:" + map2);

      boolean equal = map1.equals(map2);

      System.out.println("Map1 and map 2 are equal:" + equal);

      map2.put(Tutorial.Javascript, "5");

      equal = map1.equals(map2);

      System.out.println("Map1 and map 2 are equal:" + equal);
   }
}

The code above generates the following result.
