AGA (The South African Golf players Association) is hosting a virtual golf competition. Both professional as well as amateur golf players can register to take part in the competition. A professional golf player is defined as a person who is a member of the SAGA and is ranked on the professional list of golf players. Amateur golf players are divided into two categories for the competition, viz.1 - student (university or college) and 2 - adult. On registration the participants need to provide their ID-number and name. Professional golf players also need to indicate the number of years that they have been members of SAGA and their position on the professional golf players’ list. Amateur golf players need to provide the category they will participant in (1 or 2 – see previous paragraph). The information of a number of participants has been captured in the text file players.txt. The text file is provided. Example of the first 4 lines of text in the text file: A registration code must be generated for each participant. The registration code for a professional golf player must consist of the letter P as the first character, followed by the player’s rank and age, a dash character (-) and the number of years that the player has been a member of SAGA. Example: The registration code for a 45 year old professional golf player who is ranked number 61 and has been a member of SAGA for 7 years will be P6145-7 The registration code for an amateur player must consists of the letter A as the first character, followed by a 2 digit random number in the range from 10 to 99, the player's age, a dash character (-) and a digit indicating the player’s category. The category codes are 1 for a student and 2 for an adult. Example: The registration code for a 20 year old student who is an amateur golf player with 67 as the random 2 digit number will be A6720-1 A A registration fee must be calculated. The registration fee for professional players is R800 with a discount of 2.5% for each year that the player has been a member of SAGA. The registration fee for amateur players is R450 with a 7.5% discount for students. From the given information, identify all necessary classes with their attributes, constructors and methods. Two concrete classes AmPlayer and ProPlayer and one abstract class, Player, should be amongst the identified classes. You should also create at least one interface, of your own, that should be implemented by the abstract class. Write code of all the identified classes and interface(s). The solution must contain set (mutator) and get (accessor) methods for all the instance variables. Use set methods to assign data to the instance fields. Abstract methods must be used to ensure the re-use of as much code as possible and to ensure polymorphic behaviour. Therefore no code or instance variables may be duplicated. Validation: Do validation on the ID-numbers and categories of participants as part of the relevant set methods as explained below. ID-numbers must have exactly 6 digits. The IDnumbers must be validated in the Player super class as part of the set method for the IDnumber instance field. Validity testing of the IDnumbers must include testing whether the length of the given IDnumber is correct and testing whether the ID-number contains only digits. Assign the string 000000 to the ID-number instance field if the ID-number is invalid. NOTE: You do not have to validate the month-value and year-value. There are two categories for amateur players, namely 1 and 2. Validate the category in the set method for this instance field. Assign the value of 0 to the category instance field if an invalid value is received as category. Other specifications: The methods to calculate the discount amount and the amount due must receive the registration fee as parameter. ID-numbers consist of six digits which is the date of birth of the player in the format yymmdd. You may use the value 2020 to calculate the player’s age
