第五周作业——字体设置

下面是字体设置的代码，但是有一点小问题就是，可以显示出字体选择的框架，但是却无法现在字体，还是有待改正的说啊，

import java.awt.*;
import java.awt.font.*;
import javax.swing.*;
import java.applet.*;
import java.awt.event.*;
import javax.swing.JTextField;
import javax.swing.JScrollPane;

public class FontSet extends Applet implements ItemListener
{
	
	Label lb=new Label("请选择字体");
	//TextField tf =new TextField(50);
	Choice txt=new Choice();
	public void init()
	{
		add(lb);
		txt.addItem("黑体");
		txt.addItem("宋体");
		txt.addItem("微软雅黑");
		txt.addItem("楷体");
		add(txt);
		txt.addItemListener(this);
		//add(tf);
	}
	//@Override
	public   void itemStateChanged(ItemEvent e) {
		// TODO Auto-generated method stub
		
	}
	}
 class FontSet1
{
	
	
	public static void main(String args[])
	{
		FontFrame frame=new FontFrame();
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.show();
		
	}
	

}

	public FontFrame()
	{
	 setTitle("");
	 setSize(WIDTH,HEIGHT);
	 FontPanel panel=new FontPanel();
	 Container contentPane=getContentPane();
	 contentPane.add(panel);
	 }
	public static final int WIDTH=300;
	public static final int HEIGHT=140;
	}


class FontPanel extends JPanel
{
	
	public void paintComponent(Graphics g)
	{
		super.paintComponent(g);
		Font f=new Font("宋体",Font.BOLD+Font.ITALIC,20);
		g.setFont(f);
		g.drawString("Java欢迎您!", x, y);
	}
	public int x=55;
	public int y=50;}
