Introduction to Java Programming.

 Developing applications requires much forethought and planning. This project will guide you through the various steps of designing a program that meets a set of requirements. When requirements are understood, software development techniques and tools can be applied to design the objects needed by the program. Once the design has been determined, program logic can be defined. Finally, writing source code can begin. For this assignment, you will need to refer to a set of requirements, design the program, and then create the code. Application Requirements You have been requested to develop a Java application for a large company that provides members and the general public an online product catalog for ordering items like books, DVDs, clothes, household products, and so forth. There are several levels of users, including public (user has not registered), level 1 member, level 2 member, and level 3 member. The level 1 member pays a small monthly subscription fee. Level 2 members are associated with a small business who pays an annual fee covering less than 100 members. Level 3 members are employees of large corporations (more than 100 members) who subscribe annually. As the level increases, so does the discount. The following list highlights these requirements. The requirements for the application are as follows: •The application will act as an online ordering system. •The company accepts orders online and ships those items to the customer address. •Customers must create a line of credit prior to placing an order. •Customers view products from the catalog of items. •Customers place orders. •The administrator updates account information on behalf of members. •Administrators add, delete, and modify items in the catalog. •The application is able to run under most operating systems, including UNIX and Windows, and has a modern graphical user interface. •The application is designed for future growth.
