Cannot resolve symbol variable getSelectedIndex

Question

I was having trouble trying to copy and paste the code here it said something about having unformatted?? i dont know its my first time but here is the troublesome code i'll link a pastebin so you can see too

whole code: http://pastebin.com/p6RQiSLz

the problematic code:

    //City (JList with txtfield)

    pane.add(lblCity);
    lblCity.setForeground(Color.BLACK);
    lblCity.setBounds(5,260,80,25);

    pane.add(list);
    list.setSelectedIndex(0);
    list.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);
    list.setBackground(Color.BLACK);
    list.setForeground(Color.WHITE);
    list.setBounds(90,260,150,100);
    list.setEnabled(false);
    pane.add(txtCity);
    txtCity.setBounds(90,380,150,25);

//================================TROUBLED BLOCK OF CODE============================================

    list.addListSelectionListener(new ListSelectionListener(){
        public void valueChanged(ListSelectionEvent er){
            txtCity.setText(listCity[listCity.getSelectedIndex]);
        }
    });

getSelectedIndex should me a method, so "getSelectedIndex()"? — ilj, Sep 29 '15 at 17:23
its "Cannot resolve symbol variable getSelectedIndex" its the title :/ take a look at the paste bin the whole code is there — Oscar Cubz, Sep 29 '15 at 17:30
ok, so it's an array. you probably want something like "listCity[list.getSelectedIndex()]". — ilj, Sep 29 '15 at 17:31

listCity is an array and arrays don't have getSelectedIndex properties, there isn't even the concept of a "selected element" for arrays. You probably want the item that's selected on the JList made from listCity, so instead of listCity.getSelectedIndex, try list.getSelectedIndex(). That should at least compile.
