Java Object Oriented Programming Create a Shape class that shall have color and filled instance variables of enum Color and boolean type. The filled boolean variable shall show, whether the shape is filled (colored). The enum Color shall be defined within the class having 4 color names (choose any four). Also define getArea and getPerimeter method in Shape class, both shall return 0. Create Rectangle class with length and width attributes and a Circle class with radius attribute, of type double. Properly encapsulate all fields. Circle and Rectangle shall extend Shape class and override getArea and getPerimters methods as per its type and specific formula. In Test class, create an object of Rectangle and Circle, by initializing all attributes in constructor and print both shapes' area and perimters. In Test class, define a static method with following signature, public static void printEachShapeCount(Shape... shapes) As you know, the parent type variable can hold the…

Please write the Java program for the given scenario Create a class Film with string objects which stores name, language and lead_actor and cat-egory (action/drama/fiction/comedy). Also include an integer data member that stores the duration of the film. Include parameterized constructor, default constructor and accessory functions to film class. Flim objects can be initialized either using a constructor or accessor functions. Create a class FilmMain that includes a main function.
Design a class named Employee. The class should keep the following information infields:• Employee name• Employee number in the format XXX-L, where each X is a digit within the range0-9 and the Lis aletter within the range A-M.• Hire date* Write one or more constructors and the appropriate accessor and mutator methods for theclass.Next, write a class named ProductionWorker that extends the Employee class. TheProductionWorker class should have fields to hold the following information:• Shift (an integer)• Hourly pay rate (a double)The workday is divided into two shifts: day and night. The shift field will be an integer valuerepresenting the shift that the employee works. The day shift is shift 1 and the night shift isshift 2. Write one or more constructors and the appropriate accessor and mutator methodsfor the class. Demonstrate the classes by writing a program that uses a ProductionWorkerobject. have to use beginner code because this is an intro class.

Assignment:  Write the class XXXX_Worker with constructors, accessors, mutuators, and a toString method. A Worker has a Worker Name and Number.  Write the class XXXX_ProductionWorker which is a subclass of Worker. The production worker has a shift number (values: 1 or 2) and an Hourly pay rate. A shift number of 1 means the day shift and 2 means the night shift.  Write the class XXXX_ShiftSupervisor which is a subclass of Worker. The shift supervisor is a salaried worker who supervises a shift. The shift supervisor has a yearly bonus field. The yearly bonus is earned at year end based on performance.  Write a class, XXXX_TestWorker, which does the following: Creates one Shift Supervisor object from information entered by the user. Creates an Array of Production Workers that can hold 3 objects. Itcreates3ProductionWorkerobjectsfrominformationenteredbytheuser Prints the information about each object in the format shown below using the toString methods of the…

Define a class named Employee. This class should extend the Person class from the previous question. The class should have a constructor, which takes the name, age, employer (String) and salary (int) as parameters (in that order). The first two parameters should be passed to the constructor of the superclass and the value of the last two parameters should be stored in instance variables. The class should define the methods, getSalary which returns the salary of the employee and getEmployer which returns the name of the employer. Any methods from the previous question that need to be overridden should be overridden! Use super and instanceof as appropriate. I.e., for the following methods you should be able to call the method in the superclass for specific situations (e.g. the compareTo method in the superclass can be called if you receive anything other than an Employee, and this also holds for the equals method). The toString method only needs to append details and as such can also…
True or False a. If you do not write a constructor for a class, java will supply a default constructor. b. Java does not allow constructors to be overloaded. Abstract methods must have a void return type. d. All classes have a default equals (Object) method even if their programmer didn't write one for it. You can override a static method defined in a superclass. A method can have at most one return statement. g. A method cannot return a Wrapper class reference. h. The reserved word super can be used to access a constructor in a parent class. i. Object is an abstract class. e. f.
