JComboBox, trigger an action if the selected item is change or the same is selected

Question

I'm using a JComboBox that triggers the opening of another frame if the item selected is changed.

Here is an example of code.

String[] liste = {"Stack", "Over", "Flow"};
JComboBox comboBox = new JComboBox(liste);
comboBox.addItemListener(e -> {
    if(e.getStateChange() == 2) { //because that listener is called twice, when the item is unselected and the new is selected
        FramePopUp popUp1 = new FramePopUp(); //Class that extends JFrame
    }
});

My issue is that I want this Frame to be triggered too when the user select twice the same item.

For example:

The user selects in this case the item "Over", the Frame Pop's up, the user deal with the Frame and the informations he have to give and then close the Frame.

He remembered that he forgot to fill one information, so he re-select the item "Over" but nothing happens because he did not change the selected item.

To do that, select the text and click the `{}` button at the top of the message posting/editing form. — Andrew Thompson, Mar 29 '19 at 15:47

Just add an ActionListener instead of an ItemListener.
