get string value from HashMap depending on key name in java collection


I have a HashMap with various keys and values, how can I get one value out?

I have a key in the map called my_code, it should contain a string, how can I just get that without having to iterate through the map?

So far I've got..

   HashMap newMap = new HashMap(paramMap);
   String s = newMap.get("my_code").toString();
I'm expecting to see a String, such as "ABC" or "DEF" as that is what I put in there initially, but if I do a System.out.println() I get something like java.lang.string#F0454

Sorry, I'm not too familiar with maps as you can probably guess ;)
