用JAVA获取系统字体属性!!!

import  java.awt. * ;
import  java.applet. * ;
import  javax.swing. * ;
import  java.awt.event. * ;
public   class  A2  extends  JApplet
... {
String s="";
GraphicsEnvironment e = GraphicsEnvironment.getLocalGraphicsEnvironment();
String[] f = e.getAvailableFontFamilyNames();
JComboBox box = new JComboBox(f);
JTextField txt = new JTextField(20);


public void init()
...{
  this.getContentPane().setLayout(new FlowLayout());
  this.add(box);
  box.addItemListener(new myEvent());
  this.add(txt);
  this.setBackground(Color.pink);
  txt.setFont(new Font(box.getItemAt(0).toString(),Font.BOLD,box.getFont().getSize()));
  txt.setText(box.getItemAt(0).toString());
}
class myEvent implements ItemListener
...{  
  public void itemStateChanged(ItemEvent e)
  ...{
   if(e.getStateChange()==ItemEvent.SELECTED)
   ...{
    txt.setFont(new Font(box.getSelectedItem().toString(),Font.BOLD,box.getFont().getSize()));
    s=box.getSelectedItem().toString();
    txt.setText(s);
    
   }
   
  }
}

}
