hi
i m new to java programming and i want to make a voice chat which access a sql server db and extract ip 's of all clients that every one log in by ip (on LAN) and the problem face me now is to broadcast voice to all these ip 's specially time is nearly out this is a task in my class

here is the code in two classes that send and recieve voice between two pc
thanks
