This document describes a project to create a simple web browser application in Java. The browser allows users to browse HTTP sites, open multiple windows, search the web, download files, and use private browsing. It was created using Java programming language and Swing for the user interface to demonstrate basic concepts of building a graphical user interface and accessing the web from a Java application.

3. OBJECTIVE
To use basic concept of java.
To Create graphical user interfaces with
various user-interface controls.
To know how web browser work.

4. INTRODUCTION
Web browser is key to internet these days ,at least for
more tasks . There are many browsers for every platform
and operating System. Here we make a simple browser.

5. FEATURES
This browser was quite simple.
Browse http:// sites.
We can open new window without closing other window.
Search anything.
Download Files save download menu.
Use private window to private Browsing.
personalize Browser with extra functionality or style use
add-ons

7. Project Description
 How we access the Web from Java
 URL is an object
 Open a connection, then a stream.
 Basically, treat it like a file.
 Creating a Web browser in Java
 JEditorPane understands HTML (Text)
 Have to deal with hyperlinks as an event

8. Design Menu
public class Menu extends JFrame
implements ActionListener{
private JEditorPane display=new JEditorPane();
public JButton cut=new JButton("CUT");
public void frameHandler() {
setTitle("Menu");
setSize(400,400);
setVisible(true);
setResizable(false);
setLayout(null);
setLocationRelativeTo(null);
addComponentsToFrame(getContentPane());
}
public void addComponentsToFrame(Container Pane) {
Insets insets=getInsets();
Pane.add(cut);
cut.setBounds(20-insets.left,30-insets.top,80,30);
}

9. Design Options
public class Options extends JFrame {
public JEditorPane display=new JEditorPane();
public JButton general=new JButton("General");
public void frameHandler() {
setTitle("Options");
setSize(400,400);
setVisible(true);
setResizable(false);
setLayout(null);
setLocationRelativeTo(null);
addComponentsToFrame(getContentPane());
}
public void addComponentsToFrame(Container Pane) {
Insets insets=getInsets();
Pane.add(general);
general.setBounds(20-insets.left,30-insets.top,150,30);
}
}

/**
* A Simple Web Browser
* Uses a JEditorPane() which knows how to interpret HTML
**/
// Lots of imports!
import java.awt.*;
import java.awt.event.*;
import java.net.*;
import javax.swing.*;
import javax.swing.event.*;
import javax.swing.text.html.*;
We need all of these for
Swing, networking, I/O
(Input/Output exceptions),
and HTML processing.
Simple Web Browser

11. *
public class Browser extends JFrame {
/// Fields
/** A field for the URL to be entered **/
private JTextField locationTextField;
private JEditorPane displayEditorPane;
Simple Web Browser

12. JEditorPane gets a
scrollpane
JScrollPanes contain
something that is scrolled—
here, a JEditorPane.
We put the JScrollPane in
the Center so that it gets
emphasized in the
BorderLayout renderer.
displayEditorPane = new JEditorPane();
displayEditorPane.setContentType("text/html");
displayEditorPane.setEditable(false);
displayEditorPane.addHyperlinkListener(this);
getContentPane().setLayout(new
BorderLayout());
getContentPane().add(buttonPanel,
BorderLayout.NORTH);
getContentPane().add(new
JScrollPane(displayEditorPane),
BorderLayout.CENTER);

13. *
private URL verifyUrl(String url) {
if (!url.toLowerCase().startsWith("http://"))
return null;
// Verify format of URL.
URL verifiedUrl = null;
try {
verifiedUrl = new URL(url);
} catch (Exception e) {
return null;
}
return verifiedUrl;
}
Dealing with exceptions in all these cases is
required. The compiler flags these as errors.
How we load pages

14. *
Accesses to the
network can (of
course!) lead to
network errors, so we
have to deal with that
possibility.
private void showPage(URL pageUrl, boolean
addToList) {
try {
displayEditorPane.setPage(pageUrl);
URL newUrl =
displayEditorPane.getPage();
locationTextField.setText(newUrl.toString());
} catch (Exception e) {
System.out.println("Unable to load
page");
}
}
But there are exceptions

16. Browsing DIU Website

17. Google and Facebook

18. Reasons of choosing
this project
 Curiosity
Integral part of internet users
It is one of the software that we use most
during internet surfing for visiting web sites or
reaching out to any information available.

19. Benefits Of The Project
 After doing this project we know how a
web browser work.
 know many features of GUI.
Getting more idea about basic concepts of
java
Getting more experience about making any
project.

20. Conclusion
Easier to develop
More useful for the users
Easier to maintains and keep secure
Easier to grow as grow
