Assessment task  
A local city council proposed an innovative plan to reduce the number of private cars on the inner-city roads.Under the new proposal residents will be given five capped free travels on the public  transport(rail/bus/ferry) during the day. Residents will be issued a membership card with a client id and  pin number to be used for sign-in and sign-off at kiosks before boarding and after exiting the service. Each  travel over the capped limit will be charged a flat rate of $3.00. The application should be implemented as  a client/server model using java UDP sockets. The client program handles all the data entry and menu  selections (1. In 2. Out 3. Exit). The java datagram packet uses connectionless communication and allows  multiple clients to communicate concurrently with the UDP server.


All validations should be processed only on the server side. 
Appropriate validation/Error messages: 
1. Invalid client (The client id does not exist on the server) 
2. Invalid password (The password for the client id does not match) 
3. Already signed-in (Attempt to sign-in without sign-off) 
4. Already signed-out (Attempt to sign-off without sign-in) 
5. Welcome  
6. Good bye
