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:

- The Java Programming class has two types – remote and in-person. For remote students, the weighted score comprises of midterm, final, assignments and discussion. The weights for each are 30%, 30%, 30% and 10% respectively. For in-person students, the weighted score comprises of midterm, final and assignments. The weights for each are 30%, 30% and 40%. Write a generic class Students.java which has a constructor that takes three parameters – id, name, and type. Type will represent if the student is ‘remote’ or ‘in-person’. A toString() method in this class will display these details for any student. A generic method score() will be part of this class and it will be implemented by inherited classes. Write accessors and mutators for all data points. Write two classes RemoteStudents.java and InPersonStudents.java that inherits from Student class. Show the use of constructor from parent class (mind you, RemoteStudents have one additional parameter – discussion). Implement the abstract method…Write a Java class Person for dealing with persons. Your class must have the following features: Person id: long name: String gender: String + Person() + Person (id: long, name: String, gender: String) + Create setter and getter for all data fields. + Override toString() method: you have to return required data Fields values. Constructor: public Person(): A default constructor, should initialize the data fields to their default values. public Person (SSN: long, name: String, gender: String): A constructor with parameters, that creates the person object by setting specified parameters. Instance methods: public void setName(name: String): Used to set the full name of the person. public void setGender(gender: String): Used to set the gender of the person. public long getId(): This method returns the id of the person. public String getGender(): This method returns the gender of the person. public String getName(): This method returns the full name of the person. public String…Design and implement Java program as follows:(1) There will be a Gift class with following attributes: id (combination of numbers and letters),size (values S, M, or L), and price(2) There will be two child classes FruitBasket and SweetsBasket with the following additionalattributes: FruitBasket: number of fruits, include citrus fruits indication (true or false) SweetsBasket: include nuts indication (true or false)(3) The Gift class hierarchy must provide the following Functionality: On creation, a gift instance must be given all attribute values except price which must becalculated and number of fruits which must be set by system All attribute values can be changed after creation except id and the values that arecalculated or set by the system Price is calculated as follows:o There is a flat fee of 19.99 for S gift, 29.99 for M gift, and 39.99 for L gift.o Fruit basket gift has additional fee of 5.99 when it has citrus fruits.

- Write a class definition that creates a class called leverage with one private data member, crowbar, of type int and one public function whose declaration is void pry(). Opp JavaFollowing the instructions presented in the Lecture 4.5 and 4.6, complete the class Bag we discussed in the lectures. It should include all the data members, constructors, as well as all the member functions we have discussed. To be more specific, the class should have an interface shown as following: class Bag { private: int items[100]; int itemCount; public: Bag(); int getItemCount(); bool add(int newItem); void display(); bool contains(); bool remove(int a); int getSum(); }; Please complete all the member functions listed above including the default constructor. Then add following member function to the class: getMax() This function returns the largest integer stored in the Bag without changing the position of each integer stored in the Bag. Write a C++ program in a .cpp file (source file) that include above class Bag and perform following tasks: Use function rand() to randomly generate 80 integers between 0 and 99 and put them into an object of the class Bag.

- Answer the given question with a proper explanation and step-by-step solution. The base class Pet has protected fields petName, and petAge. The derived class Cat extends the Pet class and includes a private field for catBreed. Complete main() to: create a generic pet and print information using printInfo(). create a Cat pet, use printInfo() to print information, and add a statement to print the cat's breed using the getBreed() method.Write a class Distance which has two private data members (int feet,float inches). The class has three constructors which are having no parameter - values of both feet and inches are assigned zero. having two numbers as parameters - the two numbers are assigned as feet and inches respectively. having one number as parameter - both feet and inches are assigned that number. Provide getters and setters for data members. Now write a main class which demonstrate the functionality of above class by calling all constructors, setters & getters. Create 1 object using default constructor, and use setters to set values, then getters to print values. Create a second object using constructor having two parameters, provide values, then print values on screen. Create third object by using third constructor having one parameter, after that print values on screen.C++ Language Please Write a program that implements four classes: NPC, Flying, Walking, and Generic for a fantasy roleplaying game. Each class should have the following attributes and methods: NPC -a parent class that defines methods and an attribute common to all non-player characters (npc) in the game. a private string variable named name, for storing the name of the npc. a default constructor for setting name to "placeholder". an overloaded constructor that sets name to a string argument passed to it. setName - a mutator for updating the name attribute getName - an accessor for returning the npc name printStats - a pure virtual function that will be overridden by each NPC subclass. Flying - a subclass of NPC that defines a flying npc in the game a private int variable named flightSpeed for tracking the speed of the npc. a default constructor for setting flightSpeed to 0 and name to "Flying" using setName. setFlightSpeed - a mutator that accepts an integer as it's only argument…
