Question

How to get the previoulsy selected value in a combobox. i WANT the current and the previously selected value of the combobox.

Answer 1

Just add to combobox ItemListener. When item is changing in itemStateChanged arrives 2 events. ItemEvent.DESELECTED and ItemEvent.SELECTED with corresponding item's values. Just write something like this:
        comboBox.addItemListener(new ItemListener() {
            Object prevValue;
            public void itemStateChanged(ItemEvent e) {
                if (e.getStateChange() == ItemEvent.SELECTED) {
                    //do what you need with prevValue here
                } else {
                    prevValue = e.getItem();
        });
