Check if there are any selected items in the combobox. 
if (box == null) {
    return false;
if (box.getModel().getSize() > 0) {
    return box.getSelectedItem() != null;
return false;
ObjectgetSelectedItem(Object combo)
get Selected Item 
return ((JComboBox) combo).getSelectedItem();
StringgetSelectedName(JComboBox comboBox)
get Selected Name 
return (String) comboBox.getSelectedItem();
StringgetSelectedString(JComboBox jcb)
get Selected String 
return (jcb.getSelectedIndex() == -1) ? null : (String) jcb.getSelectedItem();
EgetTypedSelectedItemFromCombo(JComboBox combo)
Since JComboBox.getSelectedItem() returns a plain Object, this allows us to get the appropriate type of object instead. 
int index = combo.getSelectedIndex();
return index != -1 ? combo.getItemAt(index) : null;
voidsafeSelectFirst(JComboBox cb)
safe Select First 
if (cb.getModel().getSize() > 0) {
    cb.setSelectedIndex(0);
voidselectComboBoxItem(JComboBox jComboBox, String name)
select Combo Box Item 
Optional itemToSelect = Optional.absent();
for (int i = 0; i < jComboBox.getItemCount(); i++) {
    final Object item = jComboBox.getItemAt(i);

        return;
voidselectWithoutNotifyingListeners(JComboBox comboBox, int selectedIndex)

if (il != null) {
    for (ItemListener x : il)
...
voidsetComboSelection(JComboBox cb, String sel)
