Hello All, I'm not very good at Java...
With this piece of Java code, how could I modify the StyleOptions.ja va program to allow the user to specify the size of the font, while using the text field to obtain the user’s input.
Thanks.

import javax.swing.*;
import java.awt.*;
import java.awt.event. *;
public class StyleOptionsPan el extends JPanel
{
private JLabel saying;
private JCheckBox bold, italic;
public StyleOptionsPan el()
{
saying = new JLabel ("Say it with style!");
saying.setFont (new Font ("Helvetica" , Font.PLAIN, 36));
bold = new JCheckBox ("Bold");
bold.setBackgro und (Color.cyan);
italic = new JCheckBox ("Italic");
italic.setBackg round (Color.cyan);
StyleListener listener = new StyleListener() ;
bold.addItemLis tener (listener);
italic.addItemL istener (listener);
add (saying);
add (bold);
add (italic);
setBackground (Color.cyan);
setPreferredSiz e (new Dimension(300, 100));
}
private class StyleListener implements ItemListener
{
//--------------------------------------------------------------
// Updates the style of the label font style.

public void itemStateChange d (ItemEvent event)
{
int style = Font.PLAIN;
if (bold.isSelecte d())
style = Font.BOLD;
if (italic.isSelec ted())
style += Font.ITALIC;
saying.setFont (new Font ("Helvetica" , style, 36));
}
}
}
