   • In Java, what event is *continuously* fired on mouse button down?

     Top Answer

     Answered Dec 30, 2009 · 6 votes

     James Goodwin's code will not work. mousePressed and mouseReleased are both fired from the GUI thread, so blocking in mousePressed will prevent mouseReleased from ever being fired, meaning the loop will continue forever.

     If you already have a seperate thread for processing then use mousePressed to indicate to that thread that the event should start, and mouseReleased to stop.

     If you don't have a separate thread and don't want the hassle, a Timer is probably the easiest way. javadoc on Timer.

     Specifically, you should create a TimerTask that does whatever it is you want to do multiple times and queue it using Timer.schedule:

     Timer timer = new Timer();TimerTask task = new MyTimerTask();-private class MyTimerTask extends TimerTask { public void run() { // your code here }}-public void mousePressed(MouseEvent e) { timer.scheduleAtFixedRate(task, 0, 1000); // Time is in milliseconds // The second parameter is delay before the first run // The third is how often to run it}-public void mouseReleased(MouseEvent e) { task.cancel(); // Will not stop execution of task.run() if it is midway // But will guarantee that after this call it runs no more than one more time}-

     I'm pretty sure this is the simplest way, as it doesn't involve faffing around with inter-thread communication.

     Oh, and as Peter said, you will have to add code to account for the user mousing down on your app and mousing up somewhere else.

   • What is the difference between echo-server and client-server chat application in java?

     Top Answer

     Answered May 02, 2012 · 2 votes

     Single threads means 1 thread. Multi threading means multiple threads. What this means in term of your chat server is:

     If you have a single threaded server only 1 connection can be made to the server. Multithreading will allow you to create a new thread each time a new chat client connects and issue its own Input/output stream to send and receive chat messages.

     An echo server will just echo messages back from the 1 client connected where as a chat server will allow you to broadcast messages to other users and allow them to send messages to your client.

   • What is the IP address of the web server in Java Card 3.0 connected version?

     Top Answer

     Answered Jan 11, 2017 · 5 votes

     Obviously if it isn't directly connected to a network it cannot obtain an IP address by itself (it would not be much use if it could). If there is an IP address assigned to it it must be on the host machine, routing the packets to the smart card.

     Or, as the standard states in the JCRE spec of the 3.0.1 connected edition:

     A Java Card Platform implementation is not required to support the TCP/IP or UDP/IP on card. Connections over HTTP, HTTPS, and TLS protocols and datagrams over the UDP protocol MAY be supported over IP, as well as non-IP protocols, by using a gateway on the terminal or hosting device. The TLS protocol MUST be supported on card.

     But also:

     Applications MUST NOT be required to know that a non-IP protocol is being used.

     So basically the host will receive a TCP/IP stream, and convert it into packets towards the card.

   Feb 15, 2024 · Event Hubs uses Shared Access Signatures, which are available at the namespace and event hub level. A SAS token is generated from a SAS key and is an SHA hash of a URL, encoded in a specific format. Event Hubs can regenerate the hash by using the name of the key (policy) and the token and thus authenticate the sender.

   Usage example

   //<my namespace>.servicebus.windows.net/<event hub name>/publishers/<my publisher name>
