Requirements
- Implement a class called ClientPeer with the following characteristics:
- The class constructor takes as arguments a String (the user/sender name) and a reference to a pre-initialized Socket.
- The class implements two methods:
void sendMessage(String message)- creates a Message object and serializes it, utilising the available Socket.void sendMessage(String message, String receiver)- creates a PrivateMessage object and serializes it, utilising the available Socket.
- Implement a class called TextClient, which is executable (has a main method), with the following characteristics:
- The main method opens a Socket on the localhost (127.0.0.1) on port 9000
- While the socket connection is active, read strings of characters from the keyboard (utilizing the Console class - see System.console()) and call the sendMessage methods specified above (Note: You may choose any formatting to identify a private message, but please describe this format in the homework submission e-mail; one example is
/w John Hello!which identifies a private message to user John, with the content "Hello!").
- Implement a class called ServerPeer with the following characteristics:
- The class constructor takes as argument a reference to a pre-initialized Socket.
- While the socket connection is active, it deserializes objects of type Message and prints their formatted contents to the screen.
- Implement a class called Server, which is executable (has a main method), with the following characteristics:
- The main method must utilize an object of type ServerConfig to read a port number from a configuration file
- Utilizing the identified port number, opens a ServerSocket and listens to connections,
- Once a client is connected, creates a ServerPeer object, which utilizing the Socket obtained from the ServerSocket, reads objects from the stream, according to point 3 above.
- Modify the Message and PrivateMessage classes such that they are serializable.
Submitting
- The assignment will be evaluated automatically by the Web-CAT platform.
- You could access the Web-CAT platform using the username and the password with which you acces the electronica.curs.pub.ro intranet.
