A protocol defines the format of messages exchanged between two computers that allow the computers to communicate with one another. The table below defines a protocol for a simple guessing game (\n indicates a newline). Description Start or restart a new game. Quit the game. Guess a number. Bad request. Request (from client) restartin quit\n guess #\n Anything other than the above. Response (from server) restarted\n game_over\n i. ii. toolow\n toohigh\n correct\n out_of_guesses\n error\n For this assignment, you will implement a networked guessing game. The client will connect to a server, at which point a new game will begin. The client will have a limited number of guesses to guess a number. The client may start a new game or quit at any time. Hint use PrintWriter and BufferedReader to send/receive lines of text terminated by newlines. 1. Create a GuessingGameServer class that implements the server-side of the protocol. a. Wait for a client to connect on port 6355. b. In a loop, read requests from the client and respond to each request accordingly. c. For each new game, a new secret number between 1 and 100 must be generated. The client will have 6 guesses to guess the number. Respond with the appropriate message from the above table. If the client continues to guess after running out of guesses, treat it like a bad request. iii. The client can restart at any time (even in the middle of a game). d. If the client quits, the program should exit. 2. Create a Guessing GameClient that provides a command-line interface for the human user to play a game. a. The hostname of the server is a command-line argument. b. Connect to port 6355. c. Prompt the user to enter guesses. d. Print the appropriate output to the user (e.g. "Too low!", "Too high!", "Out of guesses!"). e. If the user quits, send the quit message to the server, close the socket, and exit the program.
