教你三分钟制作浏览器

父类,定义一个框架

import javax.swing.JFrame;

public class subJFrame extends JFrame{
 /**
  *
  */
 private static final long serialVersionUID = 1L;
 public subJFrame(){}
 public subJFrame(String title){
  super(title);
 }
 protected void frameInit(){
  super.frameInit();
  setDefaultCloseOperation(EXIT_ON_CLOSE);
 }

}

浏览器主类开始：

import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.net.*;
import javax.swing.*;
import javax.swing.event.*;

@SuppressWarnings("unused")
public class browseWeb extends subJFrame{

 /**
  *
  */
 private static final long serialVersionUID = 1L;
 /**
  * @param args
  */
 private JTextField enterField;
 private JEditorPane contentsArea;
 
 @SuppressWarnings("deprecation")
 public browseWeb(){
  super("Web browser");
  
  enterField = new JTextField( "请在此输入网址" );   
        enterField.addActionListener(  
            new ActionListener( ) {           
                public void actionPerformed( ActionEvent event ){
                    getThePage( event.getActionCommand( ) ); 
                }
             }
        );
  Container container=getContentPane();
  container.add(enterField,BorderLayout.NORTH);
  contentsArea=new JEditorPane();
  contentsArea.setEditable(false);
  
  contentsArea.addHyperlinkListener(
    new HyperlinkListener(){
    public void hyperlinkUpdate(HyperlinkEvent event){
     if(event.getEventType()==HyperlinkEvent.EventType.ACTIVATED)
      getThePage(event.getURL().toString());
    }
    });
  container.add(new JScrollPane(contentsArea),BorderLayout.CENTER);
  setSize(500,250);
  show();
  
 }
 
 private void getThePage(String location){
  setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
  try{
   contentsArea.setPage(location);
   enterField.setText(location);
   
  }catch(IOException ioException){
   JOptionPane.showMessageDialog(this,"网址错误",
     "网址出错",JOptionPane.ERROR_MESSAGE); 
  }
  setCursor(Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));
 }
 
 
 public static void main(String[] args) {
  browseWeb application=new browseWeb();
  
 }

}

生成jar文件双击即可运行，呵呵

效果:
