Employment Management System-EMS 1) Create a superclass named Employee that has the following fields: name, date of birth, email, and salary. 2) Inside the Employee class, Add a static variable: annual vacation= 30. This variable holds the days permitted for each employee as a vacation each year. 3) Accordingly, Add a static method to change the value of the annual vacation variable defined above. 4) The superclass has the following methods: • displayInfo() that shows and prints the info of the employee (name, date of birth, email, and salary). Note, displayInfo() method is overriding polymorphis: you must implement it differently in the derived classes: Programmer and Teacher. • Addemp() that add employee (ID, name). You need to use Hashmap for employee objects. Use employee ID as a key and the employee name as a value returned by the system. 5) Create two subclasses of Employee class: Programmer class and Teacher class (Use inheritance concept). • In programmer class define the following fields: ArrayList of projects (the projects the programmer work on), and ArrayList of programmers (system-developer ,web-app, mobile-app, cyber security...) • In the teacher class add the following fields: teacher's major and ArrayList of courses(the courses the teacher teach). The list of courses must be defined as an ArrayList of objects of course class. The course class has course name, course code, and course credits as fields. Do all the getter and setter methods of course class? Note for all classes above define the constructors in each class. And in all subclasses, you should have a parameterised constructor that calls the constructor in the super class (employee). Define a test class that has a main method to test all the classes you built in this project.
