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

- Which of the following is the most direct example of how information hiding is supported in Java? constructors inheritance member functions public and private specifiersQ# Which of the following might have only method signatures? Group of answer choices 1. An interface 2. An abstract class and a concrete class 3. An abstract class 4. An interface and an abstract class 5. None of these, they all require the implementation. 6. A concrete class91question In the Student.java file, build the Student class with the following specifications: Private fields String name - Initialized in default constructor to "Louie" double gpa - Initialized in default constructor to 1.0 Default constructor Public member methods setName() & getName() setGPA() & getGPA(. So in.
- Ans8 izt--7 Write the following Book class:A Book has-a title, ISBN number, author and price.o Include the following:o All instance fields (variables)o Two Constructors: a default constructor and onerequiring all fields as parameterso Methods – an accessor and mutator for each instancefieldso Create two Book objects with title, isbn, author andpriceo Print the information about the bookso Change the price of both books.o Reprint the information about the books.In Java Program - Encapsulation Write a class Animal with the following attributes: name, age, height and weightProvide constructors: (1)initialize all attributes and (2) initialize all attributes except age with default to 1 (3) default constructorEncapsulate the attributesOverride the toString to output in this manner: (name,age,height,weight)Use Java Code to this Please keep it simple 1. Create House Class with the following properties and methods Properties: a. floorSize b. noOfFloors c. noOfDoors Methods: d. switchOn()(print something here to indicate switching on) e. lightOpen()(print something here to indicate light is open) f. ovenOpen() (print something here to indicate oven is open)2. Create TownHouse Class inherit the House class a. Create a main function b. In TownHouse modify the value of the following properties (noOfFloors and noOfDoors) (you may use static value)Inside main function:3. Instantiate the TownHouse Class once (create an object with TownHouse type)4. Display all the properties/attributes5. Calling the switchOn() will automatically execute lightOpen() and ovenOpen()6. Call switchOn() function.Note: You may create separate file for each class.
- Hand-write a complete Java class that can be usedto create a Car object as described below.a. A Vehicle has-a:i. Registration numberii. Owner nameiii. Priceiv. Year manufacturedb.
