Is there a way to synchronize the entry values of a hashmap with a JComboBox. This means that as i add put more items to the hash map, the JComboBox is automatically aware that new items can be selected.

You could create your own combobox model by extending
AbstractListModel<E>, implementingComboBoxModel<E>,ListModel<E>,MutableComboBoxModel<E>, and using aTreeMap<T, E>as the nucleus of the model class (TreeMap instead of HashMap since the combobox model’s data must be maintained in a certain order). Just be sure to fire the proper data change methods whenever data is added or removed from your HashMap.
