Hi All,
Can any one tell me how to develop a Messenger using which technology (In Java)
Do you mean an Instant Messenger? Are you planning to use an existing network (like the ICQ network, the MSN network, the Jabber network...) or are you thinking of creating your own system?
If it's the second, have you thought about how the system should be structured? Should every user connect to a server or do you just want to use it for the communication between you and one other person?
If you're thinking of something like that, I would certainly use Sockets and ServerSockets (look at the
api for java.net.*). Those classes can create the communication between two computers over the internet.
If however you want to write a Client for an existing network, you'll have to look at the networks specifications (or the source code of an open source Client, if it exists).
Then there's the question of the UI (user interface) - do you want a GUI (graphical user interface) or should it be console based? For a GUI, you should use AWT or Swing, for the console version
System.in,
System.out and
java.util.Scanner should be sufficient.
