This abstract class is the superclass of `Hashtable`. Other hashtable-like data structures might also extend this class. See `Hashtable` for more information.

    public abstract class Dictionary extends Object {
        // Default Constructor: public Dictionary()
        // Public Instance Methods
                public abstract Enumeration elements();
                public abstract Object get(Object key);
                public abstract boolean isEmpty();
                public abstract Enumeration keys();
                public abstract Object put(Object key, Object value);
                public abstract Object remove(Object key);
                public abstract int size();
