Hi.
The JComboBox uses a model to get its hands on the elements to be displayed. Thus you must search the model to see if the string is already contained.
Use something like this:
    public boolean contains(JComboBox comboBox, String s) {
        int elementCount = comboBox.getModel().getSize();
        for (int i = 0; i < elementCount; i ++) {
            String t = (String)comboBox.getModel().getElementAt(i);
            if (t.equals(s))
                return true;
        return false;
    }Hope this helps,
