The client should setup a java.io.PrintWriter and a java.io.BufferedReader so it can read messages from and write messages to the client. Your client should connect to the server using the entered server host and port. If any errors exists with command line arguments exists, catch an appropriate exception, print a helpful error message, and exit. Also, check that the port number is parsable. Your client shall check that the correct number of command line arguments have been entered. Be sure your server implementation only instantiates a single Random object.Ĭlient Set-up Details Your client shall read two command line arguments: the name or the IP address of the server and the server's TCP port. For the final step in preparing for the Knock Knock message exchange is for the server to obtain a random index to the data structure and retrieve the set-up and punchline to a joke. The server should set up a java.io.PrintWriter and a java.io.BufferedReader so it can read messages from and write messages to the client. The server only needs to handle one client at a time (a single-threaded server). The server should print the client's host name and port. Your server should bind to its port and print a message to the console indicating on which port the server is listening. You may find the (regex) method helpful in parsing each line in the file. Read all of the lines from the jokes input file into an appropriate data structure that can be indexed by an integer. Each line in the jokes input file has a joke setup and a punchline separated by a '#' character. If any errors with command line arguments exists, catch the appropriate exceptions, print a helpful message to the console, and exit.
Long.parseLong(String)) and that the jokes file exists (java.io.FileReader(String)). Also, check that the numbers are parsable ((String) and java.lang. Your server shall check that the correct number of arguments have been entered on the command line.
#Knockknock could not listen on port 4444 generator#
Server Set-up Details Your server shall read three command line arguments: an integer TCP port, the name of a text file containing several knock-knock jokes, and a long seed value for a random number generator to select the next joke. Implement the knock knock joke message exchange pattern using a client-server architecture and Java sockets ( and ).
