OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
class TenNums {
private:
int *p;
public:
TenNums() {
p = new int[10];
for (int i = 0; i < 10; i++) p[i] = i;
}
void display() { for (int i = 0; i < 10; i++) cout << p[i] << " "; }
};
int main() {
TenNums a;
a.display();
TenNums b = a;
b.display();
return 0;
}
Continuing from Question 4, let's say I added the following overloaded operator method to the class. Which statement will invoke this method?
TenNums TenNums::operator+(const TenNums& b) {
TenNums o;
for (int i = 0; i < 10; i++) o.p[i] = p[i] + b.p [i];
return o;
}

- JAVA - PersonWrite the classes as shown in the following class diagram. Add a tester where you make an array of 5 person and ask the user to enter them. Then loop over the array and print them. The user may enter a Student, a Staff or even a Person. The ‘-‘ symbol means private field or method and ‘+’ means public. The classes Student and Staff inherit from PersonUse java programming language 1.1 Create a Student Object project. Create a Student class and use the provided UML diagram to code the instance fields, constructors and methods. Note: The module mark is the average of the participation mark and the examination mark - calculate this using the calcModuleMark() method. The determineStNumber() method should compile a student number with the first 3 letters of the student's name, a '#' symbol, and a 3-digit randomly generated number (make use of a for-loop to concatenate these 3-digits). The stNumber data field should be set in the constructor by calling the determineStNumber() method. The toString() method must compile a string to display the student number, participation mark, examination mark, and module mark, formatted in table format. Student number PMark EMark MMark Mar#9186 81 64 72.00 1.2 Create a testStudents class. Do the following: -Write a static method called display() which receives…1. Implement the above system using inheritance in the best possible way. Keep every object size as small as possible. Implement all methods (setter/getter/constructors and destructors) Note that the region area is 0 while the city is len*width and the country is the sum of their cities. 2. Create array of countries called Arab of 22 countries, Write a function fill that fills the arrav Arab 3. Write a method that finds the city that has the max area in a country 4. Write a method that sorts the cities in a country from the largest to the smallest area 5. Write a function that retums array of countries of the same area of Arab 6. Write a function that compares between two countries. It returns true if countryl area greater than country2 area. 7. Write a function to move a city from one country to another.

The green spots signify public. The red squares signify private. Superclass Ship is abstract because it contains the abstract method purpose. This class also implements the Comparable interface to compare ships by tonnage. Ship also has a public static integer named numShips that is incremented in the constructor to serve as a counter for the number of ships.After coding these classes, write a program named TestShips that uses them as follows:⦁ Create an array of declared type Ship that contains at least six ships (two of each concrete subclass). You can make up all of the values for the data members of each ship.⦁ The Strings returned by purpose() can be determined by viewing the Possible Output below.⦁ Process the array in an enhanced for loop to display for each ship:⦁ The actual type using the getClass() method inherited from class Object.⦁ The output of the toString() method.⦁ The value returned by the purpose()…Tape for a Turing Machine (Doubly-linked List)”.(I USE ECLIPSE & RUN CHECK ONLINE CONSOLE)A class named Tape to represent Turing machine tapes. The class should have an instance variable of type Cell that points to the current cell with the method: public Cell getCurrentCell() -- returns the pointer that points to the current cell. public char getContent() -- returns the char from the current cell. public void setContent(char ch) -- changes the char in the current cell to the specified value. Don't forget the Javadoc comments. IT WOULD HAVE A PUBLIC CLASS public void moveLeft() -- moves the current cell one position to the left along the tape. Note that if the current cell is the leftmost cell that exists, then a new cell must be created and added to the tape at the left of the current cell, and then the current cell pointer can be moved to point to the new cell. The content of the new cell should be a blank space. (Remember that the Turing machine's tape is conceptually…
- Design and implement a Java class named Book with two data members: title and price. The class should have suitable constructors, get/set methods, and the toString method. Design and implement another Java class named BookShelf which has an ArrayList data member named bookList to store books. The class should have suitable constructors, get/set methods, and the toString method, as well as methods for people to add a book (prototype: addBook(Book book)), remove a book (prototype: removeBook(Book book)), and search for a book (prototype: findBook(Book book)). Test the two classes by creating a Bookshelf object and five Book objects. Add the books to the bookshelf. Display the contents of the bookshelf. Test the removeBook and findBook methods as well. Take screenshots of your tests and submit them with your Java code (not the whole project)Java- Suppose that Vehicle is a class and Car is a new class that extends Vehicle. Write a description of which kind of assignments are permitted between Car and Vehicle variables.Implement the above system using inheritance in the best possible way.
