HospitalEmployee Inheritance help please.

ch 8 Inheritance 1. 10 points) Implement a Doctor class based on the UML below. The Doctor class extends/inherits the Hospital Employee class. Download the HospitalEmployee class. Doctor specialty String //area of expertise such as Pediatrics, Surgery, Internal Medicine Doctor(eName: String, eNumber int, hours double, pay double, special String) must call super class constructor getSpecialty(): String setSpecialty (special String):void calculateBonus(shift: String) double llnight shift 10%. evening shift -5%. day shift o% //Use calculateBonus(percent) method in HospitalEmployee createLogin0 String //create and return a login. first 2 letters of name +random number between 0-9 ployee number toString( String //must call super class toString 2. (10 points) Implement a tester class called Hospital. Specifically, Hospital should do the following in this order: Createl instantiate a HospitalEmployee object called luke that has the name Luke Skywalker, an employee number of 5432, hours worked of 40 and a payrate of $20.50 Display the status of luke using toString. Calculate and display luke's bonus. He is a satisfactory employee. Create/instantiate a Doctor object called darth with the name Darth Vader, and employee number of 9876, hours worked of 17, a payrate of $150,00. His specialty is Plastic Surgery Display the status of darth using toString Calculate and display darth's bonus using the calculateBonus method from the Doctor class. He works the evening shift. Create and display Darth's login Display the number of HospitalEmployee objects created. Hints Order of compilation: HospitalEmployee, Doctor, Hospital. All files should be in the same folderpackage. You may change the visibility modifier of the HospitalEmployee instance variables to protected. Example output Welcome to our Hospital luke Beginning state of empName: Luke Skywalker empNumber: 5432 ed: 40.0 pay $20.50 e Skywalker is a satisfactory HospitalEmployee. B $300.00 Beginning state of darth empName: Darth Vader mpNumbe Darth Vader is a Doctor and works the evening shift 9876 hours Worked: 17.0 payRate: $150.00 specialty: Plastic surgery Bonus 127.50 Darth Vader's login is Da39876 Number of Ho created Goodbye
