Create a chat client and server that can be used for communication between 2 users in different hosts. A sentence, typed by the user, will be transmitted to the server in the remote machine (only after ENTER is pressed) and the server will display the same to the screen. The server must use a welcome socket that has a dedicated port number. You can use java swing so as to create a separate display area and text area in the screen. In the text area, the client types his message and the same gets reflected in the diplay area (after ENTER is pressed), preceded by his hostname. The messages sent by the other user is also displayed in the display area.
