An arithmetic progression is a sequence of numbers such that the difference between the consecutive terms is constant. For instance, the sequence 5, 7, 9, 11, 13, 15 is an arithmetic progression with a common difference of 2. Given the class IntNumber: 1. public class IntNumber 2. { 3. public final int value; 4. 5. public IntNumber(int number) { 6. this.value = number; 7. } 8. } where value is an immutable field, that can be directly accessed (public), implement a class called ArithmeticProgression that implements the following methods: •1 public static IntNumber getArithmeticProgressionDifference(ArrayList< IntNumber> list) which returns the difference between terms of the arithmetic progression (as an object of type IntNumber) if the values of the IntNumber objects are an arithmetic progression. The method returns null in any other case. • public static void printIsArithmeticProgression(ArrayList<IntNumber> list ) which prints on the console: The list is an arithmetic…

Write a class Point with instance variables as: xCoordinate(int) and yCoordinate(int). Write public instance methods (getters & setters) for each instance variable. Now, write a class Circle with private instance variables as radius and Pi (value is 3.14). Write public setter, getter for radius, Area method for calculating Area, Draw method for radius.  Formula for calculating area=pi*r^2  Formula for calculating radius= Math.sqrt (xCordinate^2+yCordinate^2) a. Extend a Circle class from Point class such as Class Circle extends Pointb. Write a Default constructor in Circle class that sets radius, xCoordinate & yCoordinate to some default value e.g. -1;c. Write a Parameterized constructor in Circle class which takes xCoordinate, yCoordinate and radius as a parameter.Now write a ColoredCirlce class with private instance variable as color (String) and public setter & getters. Extend the ColoredCircle from Circle and do the following operations.d. Write a default constructor…
Consider the following class Date, which represents a date using three ints for month, day and year: class Date { private: int month; int day; int year; public: Date() { month = day = year = 0; } Date(int m, int d, int y) { month = m; day = d; year = y; } bool operator==(Date); bool operator<(Date); }; Write an implementation for both overloaded operators. == should return true if the Date objects are equivalent and false if not. < should return true if the Date of the calling object (left object) comes before the parameter Date object (right object) and false if not. You may assume that all objects of class Date are valid, i.e. month is between 1 and 12, inclusive; day contains an appropriate day for the given month, and year can be anything. You do not need to demonstrate calling these operators.

This question concerns writing a Student class to model a student's name, composed of a first name, middle name and last name. The Student class should meet the following specification:Class StudentA Student object represents a student. A student has a first name, middle name and last name.Methodspublic void setNames(String first, String middle, String last)// Set the first, middle and last names of this Student object.public String getFullName()// Obtain the full name of this Student with the middle name converted to an initial only.2Thinking of the problem in terms of testing, there are three requirements that must be met:1. The setNames() method sets the names stored in the object i.e. the values of firstName, middleName, lastName.2. The getFullName() method obtains the name of the student with the middle name converted to an initial only.3. The getFullName() method does not change anything – i.e. it does not modify the values of firstName, middleName, lastNameHINT: To start your…

Given the following class. (JAVA) public class FamilyMember { public String drink( ) {return “cup”;} public String eat( ) {return “fork”;} } Write a Baby class that is derived from the FamilyMember class. The Baby class has an instance variable for the age, a default constructor, and a constructor that accepts an integer. Include any other necessary methods. If a baby is older than 3 years, print that “it eats with its fork”; otherwise, “it eats with its hands”.

Test code: public static void main(String[] args) { MovieSubscriber bonus = new BonusSubscriber(); MovieSubscriber reg = new RegularSubscriber(); bonus.moviesRented = 15; reg.moviesRented = 15; System.out.println(bonus.getFee()); System.out.println(reg.getFee());
Class student inherits from superclass Person. Which assignment is legal? a) Student s = new Person(); b) Person p = new Student(); c) Student s = new Student(); d) Person p = new Person();
1) Consider the following class Date, which represents a date using three ints for month, day and year: class Date { private: int month; int day; int year; public: Date() { month = day = year = 0; } Date(int m, int d, int y) { month = m; day = d; year = y; } bool operator==(Date); bool operator<(Date); }; It asks to create an implementation for both overloaded operators. == should return true if the Date objects are equivalent and false if not. < should return true if the Date of the calling object (left object) comes before the parameter Date object (right object) and false if not. Assume that all objects of class Date are valid, i.e. month is between 1 and 12, inclusive; day contains an appropriate day for the given month, and year can be anything. You don't need to demonstrate calling these operators.
