Hello krishnaraoveera1294 and welcome to the Java Programming Forums.
I have uploaded some example code for you which is exactly what you are looking for.
This network application runs on 2 computers. The client side sits on the remote machine and takes screen shots. It then sends them over to the server application which processes the screen shots and displays them in a window. On the server side, events are captured like mouse movements and keystrokes and sent to the client machine. This program effectivly gives you remote control access to the client machine.
You may need to edit the code slightly to fit your specifications but all the ground work is here.
