How can I extract information from a web page

Question

I wanna read some information from a webpage, and then put those information together into a table. Since I only know the url, not the file path, when I use BufferedReader(new FileReader(FilePath)), there is a FileNotFoundException. How can I do that? Thanks a lot.

You can do it in following way....
First you need to create the object of URL by specifying the URL name.
URL myurl = new URL("http://www.xyz.com/index.html"); //specify your URL path here
URLConnection conn = null;
DataInputStream data = null;
String line;
StringBuffer buf = new StringBuffer();
try {
conn = myurl.openConnection();
conn.connect();
data = new DataInputStream(new BufferedInputStream(
conn.getInputStream()));
while ((line = data.readLine()) != null) {
buf.append(line + "\n");
data.close();
catch (IOException e) {
System.out.println("IO Error:" + e.getMessage());
So, at the end, you have the data in your string buffer...you can use it wherever u want.
Hope this helps
