Question

using CSCI300 java

Given the following UML Class Diagram

Club_Card
# card_num : String
# name : String
# age: int
# year: int
+ Club_Card (all parameters)
+ Setters & Getters
+ toString() : String
+ equals(x: Object): boolean

[10 pts] Define the class Club_Card, which contains:
1. All arguments constructor which accepts all required arguments from the main and instantiate a
Club_Card object.
2. Set & get method for each data attribute.
3. A toString() method which returns a String containing all attributes of Club_Card object as follows.
Assume the club_card number is AB12S3 was issued in 2018, and the holder name is Nael Moussa
whose age is 25. The toString() method returns the object data as follows:
The card number is AB12S3 was issued in 2018 for Nael Moussa whose age is 35
4. An equals() method which returns true when 2 objects of type Club_Card has exactly the same
contents otherwise it returns false.
[15 pts] Define the Yearly_card class as described in the class diagram.
1. All arguments constructor which accepts all required arguments from the main and instantiate
a Yearly_card object by calling the constructor of Club_Card class.
2. Set & get method for each data attribute.
3. The computePrice method returns the price of Yearly_ Card price as follows:

Yearly_card

- cost: double
- type : int // (1) for old cards or (2) for a new card
+ Yearly_card (all parameters)
+ Setters & Getters
+ toString(): String
+ computePrice : double

Permanent_Card

-charge: double
-Kind: String //Personal or family card
+ Permanent_Card (all parameters)
+ Setters & Getters
+ toString(): String
+ computePrice : double

2 | P a g e
 A Discount of 10% on the yearly card cost will be deducted for persons with
age less than 40.
 Moreover a fee of $100 is added to the cost of a new issued Yearly_Card
4. A toString() method which returns a String containing the data of Yearly_Card object with the
help of toString() in the Club_Card class, as follows:
A (new) Yearly_Card, the card number is AB12S3 was issued in 2018 for Nael Moussa whose age
is 35, the price = $350
[15 pts] Define the Permanent_Card class as described in the class diagram.
1. All arguments constructor which accepts all required arguments from the main and instantiate
a Permanent_Card object by calling the constructor of Club_Card class.
2. Set & get method for each data attribute.
3. The computePrice method returns the price of Permanent_Card price as follows:
 A fee of $400 is added to the initial charge of a family permanent_card.
 8% discount will be deducted for a Personal Permanent_Card if the person
age is less than 30.

 A toString() method which returns a String containing the data of Permanent_Card object with the
help of toString() in the Club_Card class, as follows:
A (family) Permanent_Card, the card number is CB12F3 was issued in 2019 for Nada Itani
whose age is 25, the price = $620

Answer 1

Tested on Java 14. Can't provide output as the question doesn't specify main method.
