I want to write code for login to websites with java. 

Here is the code : 

```
package login;

import java.net.*;
import java.io.*;

public class ConnectToURL {

    // Variables to hold the URL object and its connection to that URL.
    private static URL URLObj;
    private static URLConnection connect;

    public static void main(String[] args) {
        try {
            CookieManager cManager = new CookieManager();
            CookieHandler.setDefault(cManager);
            // Establish a URL and open a connection to it. Set it to output mode.
            URLObj = new URL("https://accounts.google.com/ServiceLogin?service=mail&continue=https://mail.google.com/mail/#identifier");
            connect = URLObj.openConnection();
            connect.setDoOutput(true);  
        }
        catch (MalformedURLException ex) {
            System.out.println("The URL specified was unable to be parsed or uses an invalid protocol. Please try again.");
            System.exit(1); 
        }
        catch (Exception ex) {
            System.out.println("An exception occurred. " + ex.getMessage());
            System.exit(1);
        }

        try {
            // Create a buffered writer to the URLConnection's output stream and write our forms parameters.
            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(connect.getOutputStream()));
            writer.write("Email=myemail@gmail.Com&Passwd=123456&submit=Login");
            writer.close();

            // Now establish a buffered reader to read the URLConnection's input stream.
            BufferedReader reader = new BufferedReader(new InputStreamReader(connect.getInputStream()));

            String lineRead = "";

            // Read all available lines of data from the URL and print them to screen.
            while ((lineRead = reader.readLine()) != null) {
                System.out.println(lineRead);
            }

            reader.close();
        }
        catch (Exception ex) {
            System.out.println("There was an error reading or writing to the URL: " + ex.getMessage());
        }
    }
}

```

I have tried this code on Facebook and Gmail but the problem is that it didn't work. 

It keep telling me that the cookies is not enabled. (I have used chrome browser and they were enabled).

***Is there any other ways to achieve this?***
