Miraki Evening Institute has been offering various CSEC subjects to the entire Caribbean population for numerous years. There success rate is the best in the region and as such has seen an exponential growth in stakeholder interest. The managers and owners are seeking to modernize the operations of the institution. One such modernization initiative is to keep track of Employees, Students and visitors. The address for all employees and students must be recorded by the system. For an address to be valid it must have the follawing attributes, street, city and parish. See Table 1 below for the minimum details stored on each category of person Table 1 Employees First Name Last Name Gender Address Students First Name Last Name Gender Visitors First Name Last Name Date of Visit Subjects Page f af 3 There are two types of employees Regular and Teachers, express this information in an enumerated dlass. Regular employees are paid a gross of $200,000.00 monthly and teachers are paid at a rate of $3,000.00 Per hour. Teachers work a maximum 30 paid hours per week and deliver no more than 5 subjects per academic year. If a teacher is delivering more than 3 subjects s/he will receive an additional $5,000.00 weekly. If the employee is a teacher the system must cakulate and display the gross weeky amount eaned, otherwise just display the gross as stated. Create an abstract super class caled Person so that Employees, Students and Visitors can derived the common attibutes. Students and Visitors cannot be inherited by any other entity. Use an interface to dedare the follawing methods printDetails0 and printDetails(Person per). The contact details (name, telephone number and email address) for the school must also be incorporated in the interface. Use another interface to declare a method called calculateGrassSalary)This method must be implemented buy the employees entity. Not all the students pursue the same number af subjects. Some may pursue 1, 2,3, 4 or more subjects, Use regular arrays to implement this functionality. All printed output must include the institution\'s name and contact details. Crete a driver class [a class with a main method) to test the logics of your programSolution
