As per spec the JSpinner does not accept keyboard input to traverse values

Use sample below and try to use up\down

Observe: No changes to value displayed

import java.awt.*;
import javax.swing.*;
import javax.swing.JSpinner;
public class JFrame2 extends JFrame {

public JFrame2() {
getContentPane().setLayout(null);
setSize(405,305);
JSpinner js = new JSpinner();
js.setSize(300, 200);
String[] values = {"one", "two", "free", "four"};
js.setModel(new SpinnerListModel(values));
getContentPane().add(js);
}

static public void main(String args[]) {
(new JFrame1()).setVisible(true);
}
}
