Java--第13周实验--任务2--编写一个FontFamily类，该类对象获取当前机器可用的全部字体名称，编写一个对话框FontDialog，该对话 - JAVA

class FontDialog extends JDialog implements ItemListener, ActionListener{
JComboBox list;
JLabel lable;
Mypanel panel;
public FontDialog(JFrame f, String s, boolean b) {
super(f, s, b);
panel = new Mypanel();
list = new JComboBox();
lable = new JLabel("字体的效果");
FontFamily fontFamily = new FontFamily();
String[] s1 = fontFamily.getfont();
for (int i = 0; i < s1.length; i++) {
list.addItem(s1[i]);
}

add(list,BorderLayout.NORTH);
add(lable,BorderLayout.CENTER);
add(panel,BorderLayout.SOUTH);
list.addItemListener(this);
panel.button1.addActionListener(this);
panel.button2.addActionListener(this);
setBounds(380, 380, 380, 380);
}

public void itemStateChanged(ItemEvent e) {
// TODO Auto-generated method stub
if(e.getSource()==list)
{
String name = (String)list.getSelectedItem();
//UIManager.put("Label.font", new Font(name,Font.BOLD,12));

//System.out.print(list.getItemAt(6));

}
public void actionPerformed(ActionEvent e) {
