import java.awt.AWTException;
import java.awt.Rectangle;
import java.awt.Robot;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.util.Date;

2. Schedule Program

##############################################################################

 import java.awt.Toolkit;

import java.util.Timer;

import java.util.TimerTask;

/**

 * Simple demo that uses java.util.Timer to schedule a task to execute once 5

 * seconds have passed.

 */

public class ReminderBeep {

  Toolkit toolkit;

  Timer timer;

  public ReminderBeep(int seconds) {

    toolkit = Toolkit.getDefaultToolkit();

    timer = new Timer();

    timer.schedule(new RemindTask(), seconds * 1000);

  }

  class RemindTask extends TimerTask {

    public void run() {

      System.out.println("Time's up!");

      toolkit.beep();

      String args[] = new String[3];

      main(args);

      //timer.cancel(); //Not necessary because we call System.exit

      //System.exit(0); //Stops the AWT thread (and everything else)

    }

  }

  public static void main(String args[]) {

    System.out.println("About to schedule task.");

    new ReminderBeep(5);

    System.out.println("Task scheduled.");

  }

}

3. Send Mail

For this we need 2 Jars:

   a. javax.mail.jar

   b. activation-1.0.2.jar

Then we need: SMTP host, port

import java.util.*;

import javax.mail.*;

import javax.mail.internet.*;

import javax.activation.*;

public class SendFileEmail

{

   public static void main(String [] args)

   {

      

      // Recipient's email ID needs to be mentioned.

      String to = "pavan.x.mr@oracle.com";

      // Sender's email ID needs to be mentioned

      String from = "web@gmail.com";

      // Assuming you are sending email from localhost

      String host = "localhost";

      // Get system properties

      Properties properties = System.getProperties();

      // Setup mail server

      properties.setProperty("mail.smtp.host", host);

      properties.setProperty("mail.smtp.port", "465");

      // Get the default Session object.

      Session session = Session.getDefaultInstance(properties);

      try{

         // Create a default MimeMessage object.

         MimeMessage message = new MimeMessage(session);

         // Set From: header field of the header.

         message.setFrom(new InternetAddress(from));

         // Set To: header field of the header.

         message.addRecipient(Message.RecipientType.TO,

                                  new InternetAddress(to));

         // Set Subject: header field

         message.setSubject("This is the Subject Line!");

         // Create the message part

         BodyPart messageBodyPart = new MimeBodyPart();

         // Fill the message

         messageBodyPart.setText("This is message body");

         

         // Create a multipar message

         Multipart multipart = new MimeMultipart();

         // Set text message part

         multipart.addBodyPart(messageBodyPart);

         // Part two is attachment

         messageBodyPart = new MimeBodyPart();

         String filename = "file.txt";

         DataSource source = new FileDataSource(filename);

         messageBodyPart.setDataHandler(new DataHandler(source));

         messageBodyPart.setFileName(filename);

         multipart.addBodyPart(messageBodyPart);

         // Send the complete message parts

         message.setContent(multipart );

         // Send message

         Transport.send(message);

         System.out.println("Sent message successfully....");

      }catch (MessagingException mex) {

         mex.printStackTrace();

      }

   }
