    That is too complicated a project for someone that wants to learn java.
    Start with the basics and build your knowledge before trying something so complicated.

    I think sockets can be used to send and receive data between internet sites.

    Sockets are a basic class. Other classes build on them. I imagine that someone has written some higher level classes and methods that will help you. Those classes are not part of Java SE. You'll have to do a search on the internet to see what is available.

    The Socket class is part of the Java SE. Not the others.

    Sorry, video chat is too complicated. I don't know if I have seen code to do that.
    There are lots of text chat examples here on the forum and on the internet. Do a Search for them.

    the code is not working
    Can you explain what "not working" means?
    If there are error messages, copy the full text and paste it here.
