- Create a class IntArray. Create two constructors. Nullary constructor create an array of size 10 and initiazes all values to 0. Parametrized constructor has signature IntArray(int num, int s). Thiscreates an array of size s and initializes all values. c++arrow_forwardLab 10 Using an interface to share methods It is often the case that two or more classes share a common set of methods. For programming purposes we might wish to treat the objects of those classes in a similar way by invoking some of their common routines.For example, the Dog and Cat classes listed below agree on the void method speak. Because Dog and Cat objects have the ability to “speak,” it is natural to think of putting both types of objects in an ArrayList and invoking speak on every object in the list. Is this possible? Certainly we could create an ArrayList of Dog that would hold all the Dog objects, but can we then add a Cat object to an ArrayList of Dog?Try running the main program below as it is written. Run it a second time after uncommenting the line that instantiates a Cat object and tries to add it to the ArrayList. import java.util.*;public class AnimalRunner{ public static void main(String[] args) { ArrayList<Dog> dogcatList = new ArrayList<Dog>();…arrow_forwardMust be in JAVA.

- 1) Implement a class Students Scores that models the scores of 30 students in four assessment components (Midterm, HWs, Labtest and Final). The class should use 2D array of double values and should provide methods to set and get the scores for any student at any assessment component. It should also provide methods to get the maximum, minimum, and average scores for any component. Your methods may look like the following: public void setScore (int studentID, String component, double temperature) public double getScore (int studentID, String component) public int getMaximumScore (String component) public int getMinimumScore (String component) public int getAverageScore (String component) 2) Document your class and produce a test program 'ScoresTester' that fill the scores with random marks and display the maximum, minimum and average scors.arrow_forwardWrite c# equivalent statements for the following: There is a book library. Define classes respectively for a library. The library must contain a name and a list of books (use array). The books only contain author name as information. In the class, which describes the library, create methods to add a book to the library, to search for a book by a predefined author, and to delete a book from the library. Write a test class, which creates an object of type library, adds several books to it. Implement a test functionality, which finds all books authored by Stephen King and deletes them. Finally, display information for each of the remaining books.arrow_forwardGoal 1: Update the Fractions Class Here we will overload two functions that will used by the Recipe class later: multipliedBy, dividedBy Previously, these functions took a Fraction object as a parameter. Now ADD an implementation that takes an integer as a parameter. The functionality remains the same: Instead of multiplying/dividing the current object with another Fraction, it multiplies/divides with an integer (affecting numerator/denominator of the returned object). For example; a fraction 2/3 when multiplied by 4 becomes 8/3. Similarly, a fraction 2/3 when divided by 4 becomes 1/6. Goal 2: Update the Recipe Class The Recipe constructors so far did not specify how many servings the recipe is for. We will now add a private member variable of type int to denote the serving size and initialize it to 1. This means all recipes are initially constructed for a single serving. Update the overloaded extraction operator (<<) to include the serving size (see sample output below for an…arrow_forward
