1) All the Homeworks are individual assignments. No group work allowed.

2) This electronic version of this assignment is due Nov 15th

10:00AM(Sunday).3) Please include proper comments in your programs.

4) If it is a programming assignment, you would need to submit both electronic

copy (to pgundamraju@nvcc.edu) and a hard copy. Same timings apply for

both the submissions.

5) Non-submission of homework electronically OR manually will result in a 0

possible.

Total: 50 Points

Question: Algorithm: 10 points Code/Program: 40 points

Programming Assignment 3 simulates Java Classes. For the below assignment welearn to create/design our own data type.

Write an algorithm and aJava Program for the below scenario:

We simulate a Car Reservation System where in users 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.

There are two types of customers: Preferred (P) and Normal Customers (N).

2/8

Scenario 1: View cars

When either user (Preferred or Normal customers) enters option 1, he can view a list ofall the cars and their availability. Your output should look something like below.

Car Name Availability MemberCodeCar1 True P

Car2 True P

Car3 True NCar4 True N

The carName variable is of datatype String.

The availability variable is of data type Boolean.The MemberCode variable is of datatype String.

Scenario 2: Reserve Car

When either user enters option 2, user has the ability to reserve a car. But a normal

customer with member code = N cannot reserve a car whose member code = P.A preferred customer can reserve cars with either of the member code i.e P or N.

Scenario 3: Exit

When user enters option 3, just break out from the system and your program should end

running.
