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:
Step by step
Solved in 3 steps
- What is an abstract class?4) True or False Inheritance allows a subclass to inherit properties and methods from a superclass 5) True or False A class can implement multiple interfaces. 6) What is the syntax for extending a class in Java? class Superclass extends Subclass class Subclass extends Superclass None class Subclass implements SuperclassExplain the ways subclasses can be created that are not subtypes.
- What Are Pseudo-classes?5) True or False A class can implement multiple interfaces. 6) What is the syntax for extending a class in Java? class Superclass extends Subclass class Subclass extends Superclass None class Subclass implements SuperclassDescribe the rules and conditions that must be followed when overriding a method in a subclass.
- True or False A subclass can have more fields and methods than its superclass.True or False ___(31) Key word implements is used to define a subclass from a super class. ___(32) Key word extends is used to define a subclass from an interface. ___(33) Inheritance in Java promotes code reuse.What are the rules and constraints that need to be followed when overriding a method in a subclass?
- JAVA OBJECT ORIENTED PROGRAMMING!!! How does polymorphism promote extensibility?Discuss four ways in which you can assign superclass and subclass references tovariables of superclass and subclass types.Identical-sounding variables that have been declared in a superclass and variables that have been specified in a subclass are treated as though they are two different variables.Declare a superclass and subclass. Override a method of superclass in subclass and call thesuperclass’s constructor from the subclass with proper java syntax.
