SpinnerListModel uses a java.util.List to store a sequence of data in
the model.
You can create a SpinnerListModel using an array or a list. For
example, the following code creates a model that consists of
values Freshman, Sophomore, Junior, Senior, and Graduate in an
array.
// Create an array
String[] grades = {"Freshman", "Sophomore", "Junior",
"Senior", "Graduate"};
// Create a model from an array
model = new SpinnerListModel(grades);
Alternatively, the following code creates a model using a list:
// Create an array
String[] grades = {"Freshman", "Sophomore", "Junior",
"Senior", "Graduate"};
// Create an ArrayList from the array
list = new ArrayList(Arrays.asList(grades));
// Create a model from the list
model = new SpinnerListModel(list);
The alternative code seems unnecessary. However, it is useful if
you need to add or remove elements from the model. The size of
the array is fixed once the array is created. The list is a
flexible data structure that enables you to add or remove
elements dynamically.
39.6.2 SpinnerNumberModel
SpinnerNumberModel (see Figure 39.12) is a concrete
implementation of SpinnerModel that represents a sequence of
numbers. It contains the properties maximum, minimum, and
stepSize. The maximum and minimum properties specify the upper
and lower bounds of the sequence. The stepSize specifies the size
of the increase or decrease computed by the nextValue and
previousValue methods defined in SpinnerModel. The minimum and
