Please find the class details in below.

 

Implement a Person class with the following UML diagram.
 

Person 
-

-

-

-

-

-

-
id: int firstName: String lastName: String gender: byte birthDate: java.util.Calendar maritalStatus: byte hasDriverLicence: boolean
+

+

+

+

+

+

+

+

+
Person(int id, String firstName, String lastName, String gender,

Calendar birthDate, String maritalStatus, String hasDriverLicence) setGender(gender: String): void getGender(): String

setMaritalStatus(status: String) getMaritalStatus(): String setHasDriverLicence(info: String): void getHasDriverLicence(): String toString(): String getter/setter methods for other data fields
Person is the superclass of Customer and Employee
Person class has several data fields, getter/setter and toString
Each person should have an id, a name, a surname, a gender (1: woman, 2: man), birthDate (05/05/2000), maritalStatus (1: single, 2: married) and hasDriverLicense
Since the parameter/return value types are different for getter/setter methods of gender, maritalStatus, and hasDriverLicence attributes, we show them in the UML diagram. You are responsible for implementing getter/setter methods of all data fields.
In setGender method, a string value (“Man” or “Woman”) is given, and the method should set the gender as 1 or 2.
In getGender method, a string value (“Man” or “Woman”) should be returned based on the gender
In setMaritalStatus method, a string value (“Single” or “Married”) is given, and the method should set the maritalStatus as 1 or 2.
In getMaritalStatus method, a string value (“Single” or “Married”) should be returned based on the maritalStatus
In setHasDriverLicence method, a string value (“Yes” or “No”) is given, and the method should set the hasDriverLicence as true or false.
In getHasDriverLicence method, a string value (“Yes” or “No”) should be returned based on the hasDriverLicence 
There are setter/getter and toString() methods.
 

Implement a Customer class with the following UML diagram.
 

 
Customer 
-
products: ArrayList<Product>
+

 

 

+

+

+
Customer(int id, String firstName, String lastName, String gender,

Calendar birthDate, String maritalStatus,String hasDriverLicence, ArrayList<Product> products)

Customer(Person person, ArrayList<Product> products) getter/setter methods toString(): String
Each Customer can be created with one of the given two constructors.
o    In Customer’s constructor, you are supposed to call the super class’s constructor.

Each Customer has a list of products that he/she bought.
There are setter/getter and toString() methods.
 

 

Implement an Employee class with the following UML diagram.
 

Employee 
-

-

+

+

+

+
Employee(int id, String firstName, String lastName, String gender, Calendar birthDate, String maritalStatus, String hasDriverLicence, double salary, Calendar hireDate, Department department)

Employee(Person person, double salary, Calendar hireDate, Department department)

raiseSalary(percent: double): double raiseSalary(amount: int): double getter/setter/toString methods
Employee is the superclass of Manager and RegularEmployee
Each Employee has a salary, a hireDate (the date when the employee starts to the job), a department and numberofEmployees data fields.
Each Empoyee can be created with one of the given two constructors.In Employee’s constructor, you are supposed to call the super class’s constructor.
When a new employee is created, you should increment the value of numberofEmployees by
1.

There are two overloaded implementations of raiseSalaryIn the first one, take the increment value as a double (0 >= percent >= 1) and raise the salary value based on the percentage value. For example, if the percent value is 0.5, increment the salary of the employee by 50%.
In the second one, raise the salary of the employee by the given fixed amount.
There are setter/getter and toString() methods.
 

 

Implement a RegularEmployee class with the following UML diagram.
 

 
RegularEmployee

RegularEmployee(Employee employee, double perfScore) getter/setter and toString methods
RegularEmployee is the superclass of SalesEmployee and Developer
Each RegularEmployee has a performanceScore and an amount of bonus, which will be given by his/her manager based on the performance score.
Each RegularEmployee can be created with one of the given two constructors.
o    In RegularEmployee’s constructor, you are supposed to call the super class’s constructor.

There are setter/getter and toString() methods.
 

Implement a Manager class with the following UML diagram.

Manager(Employee employee, double bonusBudget) addEmployee(e: RegularEmployee): void removeEmployee(e: RegularEmployee): void distributeBonusBudget(): void getter/setter/toString methods
Each Manager has a set of regularEmployees working in his/her department and a bonusBudget to distribute to the regular employees in the department.
Each Manager can be created with one of the given two constructors.
o    In Manager’s constructor, you are supposed to call the super class’s constructor.

In addEmployee method, you should add the given RegularEmployee e to the list of regularEmployees.
In removeEmployee method, you should remove the given RegularEmployee e from the list of regularEmployees.
Each Manager has bonusBudget to distribute it to the regular employees working in his/her department. The distribution will be based on the given formula:
o Suppose that the bonus budget of the manager is 10000 and there are 4 regular employees in the department with the following salaries and performance scores:

E1 → salary: 1000, performanceScore: 50
E2 → salary: 2000, performanceScore: 50
E3 → salary: 6000, performanceScore: 75
E4 → salary: 4000, performanceScore: 100
o    Then, the bonus value of each regular employee is:

bonus = unit * salary * performanceScore
unit = bonusBudget / ∑(𝐬𝐚𝐥𝐚𝐫𝐲 ∗ 𝐩𝐞𝐫𝐟𝐨𝐫𝐦𝐚𝐧𝐜𝐞𝐒𝐜𝐨𝐫𝐞) o Based on the example above, the bonus value for each regular employee is:
E1 → bonus: 500
E2 → bonus: 1000
E3 → bonus: 4500
E4 → bonus: 4000
There are setter/getter and toString() methods.

c) After performing these operations, print each department, its manager, its employee list with details. A sample output file is already generated based on the given sample input file and the execution scenario mentioned in Step b.
