- (1) Create two files: Car.java - Class definition, object class CarTester.java - Driver program, contains main() method Build the Car class with the following specifications: Private fields:String make - Initialized in default constructor to "none"int mileage - Initialized in default constructor to 0 Constructors:Default constructor with no parameter Overloaded constructor with two parameters Methods:setMake() & getMake() setMileage() & getMileage() (2) In your testing class, prompt the user for information to create two car objects of the Car class. Remember that the car make could contain multiple words, such as "Land Rover". Think about which method you should use in order to read in the car make information (nextLine() or next()?).A possible problem: you might notice that your nextLine() method does not read in anything when it is called after next() or nextInt() method. To fix this, you need to call an empty scan.nextLine(); to be able to read in the user's…I cannot deallocate memory in c++ classes association. class Pages{private:char* pageID;char* pageName; class Users{private:int totalFriends;int totalPages;char* userID;char* userName;char* friendsID;Users** userFriends;Pages** userPages; class SocialNetworkApp{ private:int totalUsers;int totalPages;Users* CurrentUser;Users** usersList;Pages** pagesList; The destructor of the user class cannot be called after the destructor of social network app is calledSolve as C++ Code please: 1- Creates a class Student with 3 attributes: name, id and level. a.

- Create a class called Person that will hold information about a single individual. This class should have a data section that consists of the following: Variable Name Data Type firstName string lastName string address string The Person class should have the following mutators: setFirstName(string first); setLastName(string last); setAddress(string address); The Person class should have the following accessors: string getFirstName(); string getLastName(); string getAddress(); The Person class should have the following constructors: Person(); - default Person(string first, string last); - Set other fields to an empty string Person(string first, string last, string address); Note: You must use delegating constructors to eliminate duplicate code. Main Create an array which will hold 5 Person classes. Pass the array to a function called getPeople which will fill out the array with information about people taken from the keyboard. Create a…3.a. Create an interface named Turner, with a single method named turn(). Create a class named Leaf that implements turn() to display Changing colors. Create a class named Page that implements turn() to display Going to the next page. Create a class named Pancake that implements turn() to display Flipping. Write an application named DemoTurners that creates one object of each of these class types and demonstrates the turn() method for each class. Save the files as Turner.java, Leaf.java, Page.java, Pancake.java, and DemoTurners.java. 3.b. Think of two more objects that use turn(), create classes for them, and then add objects to the DemoTurners application, renaming it DemoTurners2. java. Save the files, using the names of new objects that use turn(). 3.c. Apply Dynamic method dispatch to show the power of it and name the class as DemoTurners3.Write a class named Student. The class contains:■ Private String data field “name” that refers to the name of the student.■ Private integer data field “id” that refers to the student id.■ Private Date data field “dateCreated” that refers to the current date when anew object Student is created.■ A constructor that creates a new instance of the class student with the specifiedname and id.■ Three methods named getName(), getID() and getDateCreated() that returnrespectively the name, the id and the date when the student object was created.■ A toString() method that return a String representation of the student.2. Write a class named Course. The class contains:■ Private String data field “courseName” that refers to the name of the course.■ Private integer data field “capacity” that refers to the capacity of the course(default value 10).■ Private ArrayList of students that contains the students registered in thecourse.■ A constructor that creates a new course with the specified name.■ A…
- In Java code: Write course management program that allows professors to create course entries to the course library and student to manage course registration. Your program will present a menu with the following options: 1. Professor 1.1 creates a course 1.2 show all courses2. Student 2.1 views a course's details 2.2 enrolls in a course 2.3 drops a course 2.4 shows all enrolled courses3. Exit Follow these guidelines to define these classes 1. Professor Class Data fields: id, name, courses taught by the professor Constructors: several no-argument, multi-argument constructors Accessor methods that return the values of data fields: return name, courses Mutator methods that set the data fields, e.g, add/remove a course showCourses: list all the courses taught or created by the professor 2. Student Class Data fields: id, name, gpa, courses enrolled, etc. Constructors: several no-argument, multi-argument constructors Accessor methods that return the values of data fields:…In the project you created in previous activities. Add a class. Name it Student. That class should have student name (string), student grades (array of size 3). Create a DisplayInfo() function that displays the values of the member variables in the class. In main, create an instance of that array and fill that instance with data. Call the DisplayInfo() function from main so it prints the content of the object. A screenshot showing the code in Visual Studio and the output (on the console screen). Activity 1 code #include <iostream> using namespace stdvoid main() {cout << "Welcome to my world..." << endl;system("pause");Create a class called Staff that has the following attributes: Staff String - FirstName String - LastName String - Department String - Title Integer - UIN Staff() Staff(FirstName, LastName, Department, Title, UIN) getFirstName() - String setFirstName(String) - void getLastName() - String setLastName(String) - void getDepartment() - String setDepartment(String) - void getTitle() - String setTitle(String) - void getUIN() - Integer setUIN(Integer) - void toString() - String compareTo(Staff) - Integer equals(Staff) - Boolean PreviousNext
- Create a class called Time that has data members to represent hours, minutes and seconds. Provide the following member functions:-1. To assign initial values to the Time object.2. To display a Time object in the form of hh:mm:ss {0 to 24 hours}3. To add 2 Time objects (the return value should be a Time object)4. To subtract 2 Time objects (the return value should be a Time object)5. To compare 2 time objects and to determine if they are equal or if the first is greater or smaller than the second one.Create a C# application named ShapesDemo that creates several objects that descend from an abstract class called GeometricFigure. Each GeometricFigure includes a height, a width, and an area. Provide get and set accessors for each field except area; the area is computed and is read-only. Include an abstract method called ComputeArea() that computes the area of the GeometricFigure. Next you will create three additional classes derived from the GeometricFigure class. Name these derived classes: Rectange, Square, and Triangle. using static System.Console; class ShapesDemo { static void Main() { // Your code here } }10. Please do in java code DJ classDesign, implement and test a DJ class. A DJ object has a name - djName and an isHired attribute (boolean). Also, a DJ object has 3 musicTypes. These are references to the Music class, where the musicType is declared. In Stage 2 you will be required to declare these 3 instance variables as 1 array.A DJ object can return the value of each of its attributes, and change the value of each of its attributes. It can also display itself in the form:Kongapa, Play List: Disco, Rap, Heavy Metal is hiredImpressions, Play List: House, Hip Hop, Jazz is available
