CSC 201 Computer Science – I Homework – 2 Out: Thursday, Oct 1st 2009 Due: Thursday, Oct 13th 2009

Instructions 1) All the Homeworks are individual assignments. No group work allowed. 2) Please submit a hard copy of the assignment before start of the class by 11:05 AM. If an assignment is due Tuesday, please submit it by 10:05AM (No Exceptions). 3) Please include proper comments in your programs. 4) If it is a programming assignment, you would need to submit both electronic copy (to [email protected]) and a hard copy. Same timings apply for both the submissions. 5) Non-submission of homework electronically OR manually will result in a ‘0’ in that homework. 6) Please read and understand the Cheating Policy mentioned in the course outline document. 7) Any questions/concerns should be directed to the Professor. 8) I recommend students to start working on the assignment as early as possible. Total: 50 Points Question:

Algorithm: 10 points

Code/Program: 40 points

Write an algorithm and a Java Program for the below scenario: We simulate a Car Reservation System where in a user of this system can check the availability of a car and reserve it. The end-user will be presented with 3 options: 1) View cars 2) Reserve car 3) Exit the system. Scenario 1: View cars When the user enters option ‘1’, he can view a list of all the cars and their availability. Your output should look something like below.

Car Name Car1 Car2

Availability True True

Scenario 2: Reserve Car When user enters option ‘2’, user has the ability to reserve a car. A list of all available cars is displayed to the user. This means the cars that are already reserved should not be displayed. When user reserves a car, the availability variable becomes False. Scenario 3: Exit When user enters option ‘3’, just break out from the system and your program should end running. _______________________________________________________________________ _ Below is the skeleton I have designed. Students are free to design their own program. import scanner class; Class carrental { public static void main(String[] args) { boolean[] available = { true, true, true }; String[] carname = { “car1”, “car2”, “car3” }; System.out.println(“Welcome to ABC Car Rental Company”); System.out.println(“********************************”); System.out.println(“Menu”); System.out.println(“\n1. View Cars \n 2. Reserve Car \n 3. Exit “); do { // Scanner class to accept user input. //accept input from the user if(input == 1) { System.out.println(“ CAR NAME AVAILABILITY”); // Print out the cars and their availability. Write your code here.

} else if(input == 2) { System.out.println(“ Please enter the car number to reserve a car”); // display the available cars for the user. // If the car is not available i.e if the Boolean variable available is //‘False’ do not print that car. // If the car is available reserve that car by the setting the available //variable. } else if(input == 3) break; }while( /*condition*/); System.out.println(“You have exited the system”); }

Sample Run: Welcome to ABC Car Rental Company ********************************* MENU 1) View Cars 2) Reserve Cars 3) Exit Please enter your option: 1 **************************** CAR NAME AVAILABILITY AAA true BBB true CCC true

**************************** 1) View Cars 2) Reserve Car 3) Exit Please enter your option: 2 You want to reserve the cars: Please enter car num to reserve 0 AAA 1 BBB 2 CCC 1 Your car is reserved! 1) View cars 2) Reserve car 3) Exit Please enter your option 1 **************************** CAR NAME AVAILABILITY AAA true BBB false CCC true **************************** 1) View Cars 2) Reserve Car 3) Exit Please enter your option: 2 You want to reserve the cars: Please enter car num to reserve 0 AAA 2 CCC 0 Your car is reserved! 1) View cars 2) Reserve car 3) Exit

Please enter your option 1 **************************** CAR NAME AVAILABILITY AAA false BBB false CCC true **************************** 1) View Cars 2) Reserve Car 3) Exit Please enter your option: 3 You have exited the Car Rental system ______________________________ End ______________________________
