How to read data from a website based on user inputs through java programmi

Question

Hi
I want to get information from a website based on some inputs that I have. The inputs change everytime and based on them, different output is expected. How do I go about with it? Please advice...
Will data mining help in this? or is it used only for analysis and predictions?

you can get the webpage you need very simply like this :
Test.java
public class Test{
          public static void main(String[] args) {
               URLClient client = new URLClient();
                        // URL of a webpage
               String webPage = client.getDocumentAt("http://content-ind.cricinfo.com/slvind/engine/current/match/343730.html?template=desktop;view=main;wrappertype=desktop");
               System.out.println(webPage);
     }URLClient.java
     import java.net.*;
     import java.io.*;
     public class URLClient {
          protected URLConnection Connection;               
               public String getDocumentAt(String urlString) {
                         StringBuffer document = new StringBuffer();
                         try {
                                        URL url = new URL(urlString);
                                        URLConnection conn = url.openConnection();
                                        BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
                                        String line = null;
                                        while ((line = reader.readLine()) != null)
                                             document.append(line + "\n");
                                        reader.close();
                                   } catch (MalformedURLException e) {
                                   System.out.println("Unable to connect to URL: " + urlString);
                                   } catch (IOException e) {
                                   System.out.println("IOException when connecting to URL: " + urlString);
                              return document.toString();
          }
