SpinnerModel Interface
So far, you've seen how to interact with the main JSpinner class. The SpinnerModel interface is
the data model for the component. The definition of SpinnerModel follows:

public interface SpinnerModel {
// Properties
public Object getValue();
public void setValue(Object);
public Object getNextValue();
public Object getPreviousValue();
// Listeners
public void addChangeListener(ChangeListener);
public void removeChangeListener(ChangeListener);
}

The six methods of SpinnerModel map directly to those of JSpinner . The JSpinner methods
just redirect the method calls to that of the model, though in the case of the listener methods,
the event source is where you attach the listener.

AbstractSpinnerModel Class
The base implementation of the SpinnerModel interface is the AbstractSpinnerModel class. It
provides for the management and notification of the listener list. Subclasses must implement
the other four value-related methods of the interface. Three concrete implementations
of the SpinnerModel interface are provided: SpinnerDateModel , SpinnerListModel , and
SpinnerNumberModel .
