You can use a Hashtable. It extends the Dictionary class.

As for everyone who says it is obsolete, it probably should be but isn't. It is used in the current OSGi api in the class ServiceRegistration, and OSGi is somewhat popular these days ;-)

Of course, since Hashtable also implements Map, at least you can treat as one in your own code and still pass it in via the OSGi api as needed.

Don't use it, it's profoundly, thoroughly, obsolete and unnecessary.

Use a Map implementation such as HashMap.

Look at java.util.HashMap and java.util.Map (I understand you are looking for a dictionary equivalent in Java, and not referring to the abstract Dictionary class which is implemented by HashTable)
