public class SpinnerListModel extends AbstractSpinnerModel implements Serializable
SpinnerModel whose
values are defined by an array or a List.
For example to create a model defined by
an array of the names of the days of the week:
String[] days = new DateFormatSymbols().getWeekdays(); SpinnerModel model = new SpinnerListModel(Arrays.asList(days).subList(1, 8));This class only stores a reference to the array or
List
so if an element of the underlying sequence changes, it's up
to the application to notify the ChangeListeners by calling
fireStateChanged.
This model inherits a ChangeListener.
The ChangeListeners are notified whenever the
model's value or list properties changes.

getList()
Returns the
List that defines the sequence for this model. |

getNextValue()
Returns the next legal value of the underlying sequence or
null if value is already the last element. |

SpinnerModel whose sequence of
values is defined by the specified List.
The initial value (current element)
of the model will be values.get(0).
If values is null or has zero

SpinnerModel whose sequence of values
is defined by the specified array. The initial value of the model
will be values[0]. If values is

is not copied, the model just stores a reference to it.
This method fires a ChangeEvent if list is
not equal to the current list.

ChangeListeners. If the specified
value is not equal to an element of the underlying sequence
then an IllegalArgumentException is thrown.
In the following example the setValue call
would cause an exception to be thrown:
String[] values = {"one", "two", "free", "four"};
SpinnerModel model = new SpinnerListModel(values);
model.setValue("TWO");
