FIGURE 12.4: A font combo box.

Sometimes, we just want to create a font object without examining the fonts that are
available in the operating system. This is why Java always supports to following five basic
fonts: SansSerif , Serif , Monospaced , Dialog ,and DialogInput . In our example, we can
create the font combo box as follows.
JComboBox fontComboBox = new JComboBox(fontNames) ;

We will also create a combo box for the size.
JComboBox sizeComboBox = new JComboBox ( ) ;
for ( int i=8;i < =72; i++ ) {

sizeComboBox . addItem( i ) ;

}

The addItem method adds the specified object to the combo box. In our example, the
integers are automatically converted to objects of type Integer .
Here is the rewritten version of the NotepadFrame class that supports a font and size
chooser.
import java .awt . ∗ ;
import java .awt. event . ∗ ;
import javax . swing . ∗ ;

public class Notepad {
public static void main(String [] args)

{

NotepadFrame f = new NotepadFrame () ;
f . setVisible( true );

}

}
