Example of deleting email in Java

 String user= "dwivedicyberdairy@completejavaschool.blogspot.com";//change accordingly  

   String password="xxxxx";//change accordingly  

  

    //1) get the session object  

   Properties properties = System.getProperties();  

   Session session = Session.getDefaultInstance(properties);  

  

   //2) create the store object and connect to the current host   

   Store store = session.getStore("pop3");  

   store.connect("mail.completejavaschool.blogspot.com",user,password);  

  

   //3) create the folder object and open it  

    Folder folder = store.getFolder("inbox");  

  

   if (!folder.exists()) {  

   System.out.println("inbox not found");  

   System.exit(0);  

   }  

  

   folder.open(Folder.READ_WRITE);  

  

   //4) Get the message to delete  

   Message[] msg = folder.getMessages();  

  

    //System.out.println((messages.length+1)+" message found");  

   for (int i = 0; i < msg.length; i++) {

   }//end of for loop  

  

     // get the message number to delete (optional)  

  System.out.println("Enter message number to delete :");  

  BufferedReader br = new BufferedReader(new InputStreamReader(System.in  ));  

  String no = br.readLine();  

  //5) delete the message using setFlag method  

  msg[Integer.parseInt(no) - 1].setFlag(FLAGS.Flag.DELETED, true);  

    

  System.out.println("Message Deleted .....");  

  

  folder.close(true);  

  store.close();  

  }
