The easiest way to do this is by calling the getContent method

public final Object getContent()

This first method requires that you define a content handler for the content returned by the URL

The following example dumps the content of a URL to the System.out.stream by opening an input stream to the URL and reading one byte at a time.

Example

import java.net.*;

import java.io.*;
class Example1
{
public static void main(String args[]0
{
try {
URL url=new URL(getDocumentBase(),”main.html”);
InputStream in=url.openStream();
int b;
while(b=in.read()!=-1)
{
System.out.println((char)b);
} catch(Exception e)
{ System.out.println(“Exception Due to –>”+e);
e.printStackTrace();
}

After creating a URL object you can retrieve information stored in URL in one of three ways.

Use the getCotenet() method in the URL class to fetch the URL’s content directly

Use openConnection method to get URLConnection to the URL

Use openStream() method to get an InputStream to the URL

The full URL string is the form you are probably most familiar with

URL homepage=new URL(“http://www.xyz.com”);

You can create URL by giving the protocol, hostname, filename, and an optional port number

URL homepage=new URL(“http”,”www.xyz.com”,80);
