How to get a web page's source code from Java [duplicate]

I just want to retrieve any web page's source code from Java. I found lots of solutions so far, but I couldn't find any code that works for all the links below:

  • http://www.cumhuriyet.com.tr?hn=298710
  • http://www.fotomac.com.tr/Yazarlar/Olcay%20%C3%87ak%C4%B1r/2011/11/23/hesap-makinesi
  • http://www.sabah.com.tr/Gundem/2011/12/23/basbakan-konferansta-konusuyor#

The main problem for me is that some codes retrieve web page source code, but with missing ones. For example the code below does not work for the first link.

InputStream is = fURL.openStream(); //fURL can be one of the links above
BufferedReader buffer = null;
buffer = new BufferedReader(new InputStreamReader(is, "iso-8859-9"));

int byteRead;
while ((byteRead = buffer.read()) != -1) {
    builder.append((char) byteRead);
}
buffer.close();
System.out.println(builder.toString());

URL yahoo = new URL("http://www.yahoo.com/");
BufferedReader in = new BufferedReader(
            new InputStreamReader(
            yahoo.openStream()));

String inputLine;

while ((inputLine = in.readLine()) != null)
    System.out.println(inputLine);

in.close();

Try the following code with an added request property:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URL;
import java.net.URLConnection;

public class SocketConnection
{
    public static String getURLSource(String url) throws IOException
    {
        URL urlObject = new URL(url);
        URLConnection urlConnection = urlObject.openConnection();
        urlConnection.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.95 Safari/537.11");

        return toString(urlConnection.getInputStream());
    }

    private static String toString(InputStream inputStream) throws IOException
    {
        try (BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8")))
        {
            String inputLine;
            StringBuilder stringBuilder = new StringBuilder();
            while ((inputLine = bufferedReader.readLine()) != null)
            {
                stringBuilder.append(inputLine);
            }

            return stringBuilder.toString();
        }
    }
}
