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:

- 91question 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.Books can come in various formats, like paper books, audio books, ebooks, etc. Create a generic classBook that has as common attributes the title, the year of publication, and the author. The constructor of thisclass should instantiate all three attributes. Override the toString method of class Book that returns a stringthat contains the values of its attributes. Create a subclass PrintBook that extends Book with attributesPublisher and ISBN. Create another subclass AudioBook which has the book’s size (in MB), its playlength and the playback artist’s name as attributes. Both PrintBook and AudioBook classes override thetoString method inherited from Book. Write a Java application to demonstrate the usage of this hierarchy.IN JAVA Which is true? A. Private members can be accessed by a class user B. A mutator is also known as a getter method C. A mutator may change class fields D. An accessor is also known as a setter method

The derived class Cat extends the Pet class and includes a private field for catBreed. Complete main() to: create a generic pet and print information using printInfo(). create a Cat pet, use printInfo() to print information, and add a statement to print the cat's breed using the getBreed() method.Urgent Quick Question Write an equals method for the StepsFitnessTracker class that tests whether the one object is equal to another object that is passed as an argument (Object otherObject). The Object superclass provides an equals method that tests if two object references are equal. Your new equals method should override the Object equals method, and should test the following: • Return true if the current (this) object, and otherObject are identical references (hint: you can use the == operator for this). • Returns false if otherObject is null. • Returns false if the current (this) object and otherObject have different classes (hint: you can use the getClass() method provided by the Object superclass, see the Java 8 API documentation for details). • Casts otherObject to a StepsFitnessTracker, and tests for equality of each instance variable1 , if the instance variables are the same the method should return true. Now write an equals method for the DistanceFitnessTracker and…

The interface Range is defined below:public interface Range{ void setLimits(int x, int y); int getNumber();} Implementations of Range should exhibit the following behaviour:• The setLimits method should store its parameter values somewhere to serve as the lower and upper limits of the range appropriately.• A call to getValue should return an integer that is always greater than or equal to the lower limit and less than or equal to the upper limit.The class RandomInteger is an implementation of the interface Range. It also has the following features:• It has two fields of int type, low and high, to record the lower and upper limits of the range, respectively.• It has single constructor method that takes two integers and stores them in the appropriate fields. Note: You should make use of the setLimits method.• A call to the method getNumber should return a random number that is always within the range, i.e. greater than or equal to the lower limit and less than or equal to the upper…5) In a class definition, what type of method uses the values of the object's instance variables without changing them? a. constructor b. accessor C. instance d. mutator 17) What is the value of r after the following code executes? mySet = (2, 3, 5, 7, 11) yourSet = {5, 7, 2, 11, 3) r = yourSet == mySet a.

The Sedan constructor takes only one argument (MPG) since the type will be “Sedan” for all Sedan objects. Write the efficient() method to return true if the MPG is greater than 30.0, false otherwise.
