- Describe the rules and conditions that must be followed when overriding a method in a subclass.arrow_forwardA subclass must fully implement all of the abstract methods of its parent class in order to be considered a subclass of an abstract class. What are your thoughts on whether or not it should be done?arrow_forwardA class that is not intended to be instantiated, but used only as a base class, is called a(n) __________. a. dummy class b. subclass c. virtual class d. abstract classarrow_forward

- True/False 7. A superclass inherits behaviors from its subclasses.arrow_forwardTrue or False:Unlike other members of a superclass, constructors of a superclass are not inherited by its subclasses. This means that you must define a constructor for a class or use the default constructor added by the compiler.arrow_forwardDesign simple domain in OOP using DART classes. a.

- 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…arrow_forwardA is its parent class, while B and C are its subclasses. B and C share several features and techniques, but they implement them differently.
