Code in JAVA and see attached images for information on classes and methods A company pays its personnel on a weekly basis. The personnel are of 4 types: FixedWeekly personnel are paid a fixed amount regardless of the number of hours workedByTheHour personnel are paid by the hour and receive overtime pay for all hours worked in excess of 40PercentOfSales personnel are paid a percentage of their salesFixedWeeklyPercentOfSales personnel receive a fixed amount plus a percentage of their sales. Create a class called Personnel. This class will represent the general concept of all personnel. All 4 types of personnel are considered Personnel. FixedWeeklyPercentOfSales personnel are considered to be PercentOfSales Personnel. The Personnel class will also be Payable. You will need to create the Payable interface. It will contain just one method called earnings(). Test Run Personnel processed polymorphically: FixedWeekly personnel: Harry Clarksocial security number: 111-11-1111weekly…

Design a console program that will print details of DVDs available to buy. Make use of an abstract class DVD with variables that will store the title, yearReleased, running time and price of a DVD. Create a constructor that accepts the title, yearReleased and running time through parameters and assign these to the class variables. Create an abstract set method for the price of a DVD; also create get methods for the variables.Create a subclass InstructionalDVD that extends the DVD class and implements an iPrintable interface. The interface that must be added is shown below:public interface iPrintable { String ShowDetails();}The InstructionalDVD subclass has a private variable named category for which a get method must be written. The constructor of the InstructionalDVD class must accept the title, yearReleased, running time and category through parameters. Write the code for the setPrice() and ShowDetails() methods.Write a useDVD class and instantiate 2 objects of the InstructionalDVD…
