    Well, it uses Java Socket Programming to perform the above mentioned tasks.

    Wanna know more? Well, it creates a multicast object and uses the methods like InetAddress.getByName() and other similar other methods to meet its ends. You can search for the InetAddress class to get more info 😁 .

    Still want more? As this software is open source, u too can check the code for urself!! 😎 and ask any difficulties u face here.

    Still got some doubts? You can ask us and we would be happy to help!👍

    I think it happens in the following manner:
    • When the software starts, it broadcasts the packet to all computers on the Lan and those which have same software running responds.
    • Thus it gets a list of active users as hostnames are received as the response by the other computers.
    • Then it calculates the IP Addresses from the hostnames using getbyname() function told above.
    • The chat server starts running on a predetermined port to address the communication.
    The software uses multithreading to handle different operations separately.
    Hope it answers your query!😀
