java 中label控件可以设置超链接吗？

//URLLabel.java

import java.awt.Color;
import java.awt.Cursor;
import java.awt.Desktop;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.net.URI;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.ToolTipManager;

public class URLLabel extends JLabel implements MouseListener{
private static final long serialVersionUID = 2194613519655846206L;
public static void main(String[] args) {
ToolTipManager.sharedInstance().setInitialDelay(0);
JFrame f=new JFrame("URLLabel test");
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JLabel l=new URLLabel("http://zhidao.baidu.com/question/130767272.html","百度知道");
f.add(l,"South");
f.setSize(345,123);
f.setLocationRelativeTo(null);
f.setVisible(true);
}
public URLLabel (String ustr,String ttt){
this.ustr=ustr;
this.setText(ustr);
this.setForeground(Color.blue);//设置链接颜色
this.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));//设置鼠标样式
this.setToolTipText(ttt);//设置提示文字
this.addMouseListener(this);
}

//点击时打开默认浏览器浏览指定的页面。
public void mouseClicked(MouseEvent e) {
try {
Desktop.getDesktop().browse(new URI(ustr));
} catch (Exception e1) { e.paramString();}
}
public void mouseEntered(MouseEvent e) { }
public void mouseExited(MouseEvent e) { }
public void mousePressed(MouseEvent e) { }
public void mouseReleased(MouseEvent e) { }

private String ustr;
}

可以
你设置HTML格式，有个下划线。

用RUNTIME类运行IE，参数是你的URL
