bismillah..

Ok.. the case is, there is someone.. um.. ok.. some people I want to monitor when they got online. Not as invisible, just the regular online. So, here are the code :

MonitorThread.java

/*  * To change this template, choose Tools | Templates  * and open the template in the editor.  */

//package yahoostatusmonitor;

import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.net.URL; import javax.swing.JOptionPane;

/**  *  * @author Z10MQ.ATQ3B1T  */ public class MonitorThread extends Thread{     String names[] = null;     String listOfOnlines = null;     boolean isRunning = true;

    public MonitorThread(String nameList[]){

        this.names = nameList;     }

    public void run(){

        while (isRunning) {

            //list of online users             listOfOnlines = "";

            for (String i:names){

                System.out.println("monitoring : "+i);                 try{

                    // Create a URL for the desired page                     URL url = new URL("http://mail.opi.yahoo.com/online?u="+i+"&m=a&t=1");

                    // Read all the text returned by the server                     BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));                     String str;                     str = in.readLine();

                    if (str.equals("01")){                         listOfOnlines += "    + " + i + "n";                     }

                    in.close();

                }catch (IOException ioe) {                     ioe.printStackTrace();                 }             }

            if(!listOfOnlines.equals("")){                 //show the message status                 JOptionPane.showMessageDialog(null, "These people are online:n"+listOfOnlines);             }

            try{                 Thread.sleep(180000);             }catch (InterruptedException ie) {                 ie.printStackTrace();             }

        }

    }

    public void setRunning( boolean isRunning){         this.isRunning = isRunning;     }

}

And here is the Manager thread, just the base for another advance features :

MonitorManager.java

/*  * To change this template, choose Tools | Templates  * and open the template in the editor.  */

//package yahoostatusmonitor;

/**  *  * @author Z10MQ.ATQ3B1T  */ public class MonitorManager {

    public static void main(String args[]){

        Thread m1 = new MonitorThread(args);

        m1.start();     }

}

And to run the java class is by :

java MonitorManager <list of  users>
