I want to write a program similar to Google Talk, but much easier. An application that gives a warning message whenever users have a new message. What language would be best for me?
What the Ravi said that is absolutely right.In java Socket program you can do the chatting in the same location or region but if you want to do chatting with two person in two different location then at that time you have to purchase some space from internet.However you can get the JAVA SOCKET PROGRAMMING code from any of the J2SE book like The Complete Reference of Java. Thanks.
