A little odd workaround(mine :)), might useful to you 

final JComboBox lstA = new JComboBox();
String[] arr={"ab","cd","ef"};
lstA.setModel(new JComboBox(arr).getModel());

final JComboBox lstA = new JComboBox();
void bind()
{
  String[] arr={"ab","cd","ef"};
  // bind arr to lstA 
  lstA.setModel(new DefaultComboBoxModel<String>(arr));    
}

build your JComboBox with a dynamic ComboBoxModel

JComboBox(ComboBoxModel<E> aModel)

like http://docs.oracle.com/javase/7/docs/api/javax/swing/DefaultComboBoxModel.html 

m=new DefaultComboBoxModel();
j=JComboBox(m);

you can then add and remove elements: 

m.addElement("ab")
m.addElement("cd")

or, if you only need to put the array in the combox:

new JComboBox(new Sring[]{"ab","cd","ef"})
