Question

IN JAVA(NETBEANS) PLEASE:

The cost to become a member of a fitness center is as follows: (a) the Senior citizens discount is 30%; (b) if the membership is bought and paid for 12 or more months in advance, the discount is 15%; or (c) if more than 5 personal training sessions are purchased, the discount on each session is 20%. Write a menu driven program that determines the cost of a new membership. Your program must contain a method that displays the general information about the fitness center and its charges, a method to get all the necessary information to determine the membership cost, and a method to determine the membership cost. Use appropriate parameters to pass information in and out of a method. Implement the program as specified below: METHOD displayGeneralInformation - displays all of the costs and asks for the age Welcome to Fitness Center Service Costs 3 month membership $350 6 month membership $600 Java Programming: From Problem Analysis to Program Design 7-2 1 year membership $1000 (15% discount if paid in full) Personal training sessions $80/hour for each session (20% discount on each session if more than 5 sessions are purchased) ***If you are 55 years or older, you will receive a 30% discount Please enter your age: METHOD getDataMenu - shows the menu and returns the value entered 1. Purchase Membership 2. Purchase Sessions Choose from the Menu: METHOD: getMembershipCost If option 1 from menu above entered: A- 3 month membership $350 B- 6 month membership $600 C- 1 year membership $1000 (15% discount if paid in full) Choose your membership level: METHOD: getTrainingSessionsCost - returns training session cost If option 2 entered: Enter the number of sessions you would like to purchase: METHOD: totalMembershipCost Your total membership cost is: $…… Note: Senior citizens who buy a 12 month membership and pay in full will first receive 30% off the 1,000 and then 15% off the remaining balance. Senior citizens also receive 15% off training sessions. Discussion the 20% off first if more than 5 sessions and then discount the 15% from the balance.
