      ONE, TWO, THREE, FOUR, FIVE
   };

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

      // associate values in map1
      map1.put(Numbers.ONE, "1");
      map1.put(Numbers.TWO, "2");
      map1.put(Numbers.THREE, "3");
      map1.put(Numbers.FOUR, "4");

      // print the whole map
      System.out.println("map1:" + map1);

      // clone map1 to map2
      map2 = map1.clone();

      // print map2
      System.out.println("map2:" + map2);

   }
}

Let us compile and run the above program, this will produce the following result:

map1:{ONE=1, TWO=2, THREE=3, FOUR=4}
map2:{ONE=1, TWO=2, THREE=3, FOUR=4}
