This example demonstrates how to build three kinds of spinners. A number spinner: 
    // Create a number spinner
    JSpinner spinner = new JSpinner();
    
    // Set its value
    spinner.setValue(new Integer(100));

A list spinner: 
    // Create a list spinner
    SpinnerListModel listModel = new SpinnerListModel(
        new String[]{"red", "green", "blue"});
    spinner = new JSpinner(listModel);
    
    // Set its value
    spinner.setValue("blue");

A date spinner: 
    // Create a date spinner
    SpinnerDateModel dateModel = new SpinnerDateModel();
    spinner = new JSpinner(dateModel);
    
    // Set its value to jan 1 2000
    Calendar calendar = new GregorianCalendar(2000, Calendar.JANUARY, 1);
    spinner.setValue(calendar.getTime());
