Permanently add item to combobox

I have a comboBox which has a few items in it already. At Run time, I add an item to it, which gets added successfully. But when, at the end of the execution, the JFrame is loaded again, the recently added item isn't present. I used both the methods, using model.addElement() and using additem() and both have the same problem.

Here's the code: 

 int i = JOptionPane.INFORMATION_MESSAGE; 
       String a = JOptionPane.showInputDialog(null, "Enter new item", "Add", i);

       DefaultComboBoxModel model = (DefaultComboBoxModel) 
        cmbo0.getModel(); 
        model.addElement(a); 

            cmbo0.setSelectedItem(a);

At the moment, your combobox only lives as long as your application.

You'll need a permanent datasource that you can write to, i.e. file, database, etc.
