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 hourly charges are based on the customer categories as shown below: Charge Per Hour (RM) Type of Facility Badminton Student Staff Non-UUM Free 4.00 8.00 Squash Free 1.00 6.00 Sauna 3.00 5.00 10.00 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...

Based on the provided information above, write the UUM sport center charge calculator program by defining the Customer and SportChargeCalculatorul classes. NOTE: The files that must be submitted in your compressed file are Customer.java, SportChargeCalculatorUI.java and SportCharge CalculatorUI.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 calculate Charge () method:
