slider in bean

[Candy Bortniker]

I have created a bean that contains a slider that is to be used to change the color of a circle on the test program. Do I need setters/getters for the slider, label and textfield? Is that what I would call to put the slider on the frame?
Here's the code I have now:

 
import java.awt.*;
import java.beans.*;
import javax.swing.*;
import javax.swing.event.*;
class BlueSliderBean extends JFrame implements java.io.Serializable
{
JSlider slider = new JSlider(0,255);
private JPanel sliderPanel;
private JLabel integerlbl;
private JTextField textField;
private ChangeListener listener;
private int value = 0;
public BlueSliderBean()
{
sliderPanel = new JPanel();
sliderPanel.setLayout(new FlowLayout(FlowLayout.LEFT));
//listens for slider
listener = new ChangeListener()
{
public void stateChanged(ChangeEvent event)
{
//update text field when the slider value changes
JSlider source = (JSlider)event.getSource();
if (source.getValueIsAdjusting())
{
    int fps = (int)source.getValue();
}
integerlbl.setText("" + source.getValue());
}
};
//add a filled slider
slider.setPaintTicks(true);
slider.setMajorTickSpacing(20);
slider.setMinorTickSpacing(5);
slider.putClientProperty("JSlider.isFilled", Boolean.TRUE);
addSlider(slider, "Filled");

//add the text field that displays the slider value
integerlbl = new JLabel();
textField = new JTextField(5);
Container contentPane = getContentPane();
contentPane.add(sliderPanel, BorderLayout.CENTER);
contentPane.add(textField);
contentPane.add(integerlbl, BorderLayout.SOUTH);
}//close constructor
public void changeUpdate(DocumentEvent e){}
public void insertUpdate(DocumentEvent e)
{    updateSlider();
}
public void removeUpdate(DocumentEvent e)
{
updateSlider();
}
private void updateSlider()
{
int val = 0;
    try
    {
val = Integer.parseInt(textField.getText());
}
catch (NumberFormatException e){}
slider.setValue(val);
}
public void propertyChange(PropertyChangeEvent e)
{
    if (textField.equals(e.getPropertyName()))
{
    Number value = (Number)e.getNewValue();
if (slider != null && value != null)
{
   slider.setValue(value.intValue());
}
}
}
public void addSlider(JSlider s, String description)
{
s.addChangeListener(listener);
JPanel panel = new JPanel();
panel.add(s);
panel.add(new JLabel(description));
sliderPanel.add(panel);
}
public void setValue(int val)
{
value = val;
}
public int getValue()
{
return value;
}
}//close SliderBeanFrame
