Problem of retrieving data using JComboBox

Question

I built 6 JComboBoxes for retrieving starting day and end day. They are all in the same panel. I could get correct indexes for 6 JComboBoxes, however, I couldn't get the correct object of the month of the end day. Sometimes, I could n't get the correct object of the month of the starting day too. How could I solve this problem?

Here is part of the code:
JComboBox comboToMonth = new JComboBox();
String month[] = { "-", "JAN", "FEB", "MAR", "APR", "MAY", "JUN", "JUL", "AUG", "SEP", "OCT", "NOV", "DEC"};
comboToMonth = new JComboBox(month);
comboToMonth.setFont(universe_font);
comboToMonth.setMaximumRowCount(3);
comboToMonth.addActionListener(this);
panel.add("Center", comboToMonth);
public void actionPerformed(ActionEvent e) {
if ( e.getSource() == comboFromYear) {
     int temp = comboFromYear.getSelectedIndex();
}
