Thomas has newly opened a bookstore, selling at least four different categories of books - IT reference books, magazines, novels and cookery books etc. He intends to expand the variety of books that he in the near future. In order to build better rapport with the customers, Thomas is setting up a 'Book Lover's Club' to attract customers to sign up as members to his bookstore. With this 'Book Lover's Club', Thomas will be able to collect his customers' particulars, as well as their preferences for books. To become a member, the customer will have to pay a yearly subscription of $10. Thomas also intends to implement a saving scheme for his customers. For customers who are members of his 'Book Lover's Club', they will enjoy a 3% discount when they purchase any items in the bookstore. For members who have spent more than $1000 in a year, they will be deemed as Goldcard member, and they will enjoy 5% discount on any purchases in the bookstore. Thomas would like to implement an information system in keeping track of the sales of each category of books. The system should also indicate the best and worst selling category so that he can react to the market in time. Thomas would also like to computerise the enrolment of members into the 'Books Lover's Club'. The system will keep a database of the members' particulars and members' preferences in the books. Furthermore, the system should also upgrade the members to gold card members when they qualify for it. Write a JAVA program to implement a information system that is suitable for Thomas' bookstore.
