OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

- True or False A subclass can have more fields and methods than its superclass.True or False ___(7) An object can be created from an interface. ___(8) An object in a super class can be assigned to a subclass variable. ___(9) Overriding and overloading a method is the same.super is a special keyword that directs the compiler to invoke the superclass methods.
- True/False 7. A superclass inherits behaviors from its subclasses.Encircle/ write down the correct/missing code.Elaborate if needed by writing a comment. //this is a subclass of superclass Teacher public class ScienceTeacher { Public final boolean ScienceMajor; Science (String ScienceMajor, String name, String age){ this.ScienceMajor= ScienceMajor; super(name, age); } }When a variable declared in a subclass has the same name as a variable declared in a superclass, it is called a _______________ variable.
- PLZ help with the following IN JAVA When defining an inner class to be a helper class for an outer class, the inner classes access should be marked as: Public Private Protected Package accessAssignment: 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…True or False A class can implement more than one interface.
- Instructions JAVA LANGUAGE The Factory Method pattern provides an interface for creating objects in a superclass but allows subclasses to alter the type of objects to be created. Use NetBeans to create a Java program that implements this design pattern. Name your project TestFactory. Create an abstract superclass named Laptop. Any subclass of an abstract class must either implement all of the abstract methods in the superclass or be declared abstract itself. Copy the code below. abstract class Laptop { public abstract int getRAM(); public abstract int getSSD(); public abstract String getCPU(); public String toString() { return "RAM="+this.getRAM()+"GB, SSD="+this.getSSD()+", CPU="+this.getCPU(); } } Create a subclass named Minimum that extends your superclass. In this class, declare three (3) private variables with the following names and data types: ram (int) ssd (int) cpu (String) Copy the code below for the constructor of your Minimum class. This constructor has…In Java: Implementing a Superclass Employee Part 1: Implement a superclass Employee that has the following fields and methods. Fields: string firstName string lastName int employeeID double salary Methods: constructor method - initialize salary field to zero. setters and getters for firstName, lastName, and employeeID employee Summary method - prints all account attributes Part 2: Implement a Manager class that inherits from the Employee class. Fields: string department a Methods: employeeSummary method - prints all superclass and subclass attributes Ensure that your program has the two required classes and a test class.You have a method that requires an argument that is an instance of the superclass, and it expects you to provide it. It will function properly if you provide it with an object of a subclass rather than a superclass. Is it even possible? Where is the value in that?
