- Design a new class that contains a print and read function by creating a new object and calling the print and reading functions inside the case ( data structure in java)JAVA CLASS AND OBJECT Modify the java program/code given below. 1.) Modify the abstraction example code below by adding another class “TestCarabao” with the necessary methods “label, move, and eat”. abstract class Animal { // abstract methods abstract void move(); abstract void eat(); // concrete method void label() { System.out.println("Animal's data:"); } }Write the program of object orientation programming c++. Write a program with a class that contains an array of integers. Initialize the integer array in the constructor of the class. Then create two friend functions to the class to find the largest and smallest integers in the array. (One function should be global)Create a destructor that sets all of the elements in the array to 0.
- THIS NEEDS TO BE DONE IN C#! Modify the code below so that the base class is an abstract class. class Pokemon{ protected string Name; protected string Type; protected string Health; public override void Attack() { //body of Attack } } Make Attack abstract as well. You do NOT have to create a derived class.JAVAclass: Main.java, Quadratic.java, TestQuadratic.java Create a class called Quadratic for representing a one-variable quadratic expression of the form: ax2 + bx + c a,b and c here are the coefficients. The class should contain the following methods: * A constructor that accepts values for a, b, and c. * public double getA() * public double getB() * public double getC() * public double evaluate (int x) * will return the value of the expression at point x * public double discriminant() - that will return (b2 - 4ac) * public boolean isImaginaryRoots() - roots are imaginary if (b2 - 4ac) < 0 * public boolean isRealRoots() - roots are real if (b2 - 4ac) >= 0 // these methods can only be invoked if the roots are not imaginary * public float firstRoot() * public float secondRoot() * public boolean isPerfectSquare(); // If the first and second roots are equal * Try to override the toString methods * Write a sample main program that will work as shown below. Example output:…Complete the program and Write the output of the given code fragment: public class parent { public void someFunction() { System.out.println ("Parent Function"); } } public class child extends parent { public void someFunction() { System.out.println ("Child Function"); } public static void main(String args[]) { //insert appropriate codes to declare objects for the parent and child classes. child c1 = new child(); //insert code to call the parent method someFuntion () p2.someFunction(); c1.someFunction(); } }
