get string value from HashMap depending on key name

Question

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 str

Answer 1

If you are storing keys/values as strings, then this will work:

HashMap newMap = new HashMap();
newMap.put("my_code", "shhh_secret");
String value = newMap.get("my_code");

The question is what gets populated in the HashMap (key & value)
