Hello guys,

I have to discuss one of my confusion related to the java classes. In advanced java the concept of classes are quite complicated to understand. I am getting troubled while understanding the 'SpinnerListModel class' of java. I don't have any idea about this java class. I wonder if you are able to provide me some details about the 'SpinnerListModel class' of java wit proper example. I am waiting for your reply.

Hi friend,

The SpinnerListModel class of advanced java is related to the configuration of the list array. The SpinnerListModel class is implements the 'Serializable' class. This class also extends 'AbstractSpinnerModel' class. The simple use of SpinnerListModel class is to define list or an array. The SpinnerListModel class is mostly have inheritance of a ChangeListener. This method of SpinnerListModel class is changed whenever the there is modification in it's properties.

Hi,

Please study following example of SpinnerListModel class, which will depict you the use of this class:

import javax.swing.JSpinner;
import javax.swing.SpinnerListModel;
import javax.swing.SpinnerModel;

public class MainClass1 {

  public static void main(final String args[]) {
    JFrame frameC = new JFrame("JSpinner Dates");
    frameC.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    SpinnerModel modelC1 = new SpinnerListModel();
    JSpinner spinnerC1 = new JSpinner(modelC1);
    JLabel labelC1 = new JLabel("None");
    JPanel panelC1 = new JPanel(new BorderLayout());

    panel1.add(labelC1, BorderLayout.CENTER);
    panel1.add(spinnerC1, BorderLayout.WEST);

    frame.add(panelC1, BorderLayout.NORTH);
    frame.setSize(300, 80);
    frame.setVisible(true);

  }

}

See the following example of SpinnerListModel class. In which I have used many methods of SpinnerListModel class:

import javax.swing.SpinnerModel;

public class MClass 
{
  public static void main(String arg[]) {
    JFrame fz = new JFrame("JSpinner Sample");
    fz.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    DateFormatSymbols symbolsz = new DateFormatSymbols(Locale.FRENCH);
    String days[] = symbolsz.getWeekdays();
    SpinnerModel modelz1 = new SpinnerListModel(days);
    SpinnerModel modelz2 = new SpinnerDateModel();
    JSpinner spinnerz1 = new JSpinner(modelz1);
    JSpinner spinnerz2 = new JSpinner(modelz2);
    fz.add(spinnerz1, BorderLayout.NORTH);
    fz.add(spinnerz2, BorderLayout.SOUTH);
    fz.setSize(400, 100);
    fz.setVisible(true);
  }
}

The SpinnerListModel is very often used class of java. 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. Simply this is used for the implementation of list.
