Exercise 1-Account class • Design a class named Account that contains : • A private int data field named id for the account • A private double data field named balance for the account • A privet Date data field named dateCreated that stores the date when the account was created • A no-arg constructor that creates a default account • A constructor that creates an account with the specified id and initial balance • The getters (i.e., accessors) and setters (i.e., mutators) methods for id and balance • The getter method for dateCreated • A method named withdraw that withdraws a specified amount from the account • A method named deposit that deposits a specified amount to the account
C# Language Create a class named Account with an instance variable named account_number. Make this class a member of the Accounts namespace.
Car Class Project The car classwill havethe following attributes: •year: an integer that holds the car's model year •model: a string that holds the make of the car •make: a string that holds the model of the car •speed: an integer that holds the car's current speed Your class should contain thefollowing: A docstring that briefly describes the class and lists the attributes. The docstring will serve as the documentation for your class. •A constructor (__init__ method) that takes the car's year model and make as optional arguments. The constructor will set the value of the speed attribute to 0.•An __str__ method that returns the car's year model and makein a string. •To test your class, create acar object and use the print function to verify that the constructor and __str__ methodsare working correctly. •An accessor method which returns the value stored in the speed instance variable. Call this method getSpeed(). •A modifier method called accelerate() which adds 5 to the speed variable…

JAVA Programming Problem 3 - Book A Book has such properties as title, author, and numberOfPages. A Volume will have properties such as volumeName, numberOfBooks, and an array of book objects (Book [ ]). You are required to develop the Book and Volume classes, then write an application (DemoVolume) to test your classes. The directions below will give assistance. Create a class called Book with the following properties using appropriate data types: Title, Author, numberOfPages, Create a second class called Volume with the following properties using appropriate data types: volumeName, numberOfBooks and Book [ ]. The Book [ ] contains an array of book objects. Directions Create a class called Book with the following properties using appropriate data types: Title, Author, numberOfPages, The only methods necessary in the Book class, for this exercise, are the constructor and a toString(). Create a second class called Volume with the following properties using appropriate data types:…
class IndexItem { public: virtual int count() = 0; virtual void display()= 0; };class Book : public IndexItem { private: string title; string author; public: Book(string title, string author): title(title), author(author){} virtual int count(){ return 1; } virtual void display(){ /* YOU DO NOT NEED TO IMPLEMENT THIS FUNCTION */ } };class Category: public IndexItem { private: /* fill in the private member variables for the Category class below */ ? int count; public: Category(string name, string code): name(name), code(code){} /* Implement the count function below.
