I need help writing this code

UUM Sport Center provides sport facilities to its customers who are either students, staff or non-UUM (outsiders). The types of facilities provided and their houriy charges are based on the customer categories as shown below: Type of Facility I Badminton Squash The sport center wants you to write a program that can be used by its staff to calculate the charge to be paid by its customers. Six sample running of the program's GUI are shown below: UUM Sport Center Charg... - X UUM Sport Center Charg. O X Facility Type: Category. Facility Type: Category: Squash Student Badminton Student O Staff Staff Non-UUM Non-UUM Num Of Hours: 2 Num Of Hours: 1 Calculate Charge Calculate Charge Category: Student Category: Staff Facility Type: Squash Facility Type: Badminton Number of hours: 2 Number of hours: 1 Charge: 0.0 Charge: 4.0 UUM Sport Center Charg..

Based on the provided information above, write the UUM sport center charge calculator program by defining the Customer and SportChargeCalculatorUI classes. NOTE: The files that must be submitted in your compressed file are Customer.java, SportChargeCalculatorUI.java and SportChargeCalculatorUl.form. The incomplete definition of the Customer class is given to you as shown below: Customer . java public class Customer { private String category; //Customer category private String facType; //type of facility used private int hours; / / number of hours used //define the constructor: //define the calculateCharge () method
