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:

- ngineering Computer ScienceQ&A Libraryin c++ Create a class time24, each object is a value represented the time of day in the form hours, minutes and seconds. Provide a constructor that enables an object of this class to be initialized when it is instantiated. The constructor should contain default values in case no initializes are provided. Provide Public member functions for each of the following operations: set the time, print the time, increment the time by one second, compare two times for equality, increment the time by one hour, determine if one time is “less than” (comes before) another time, and final print the time in format 12 hours. Include any additional operations that you think would be useful for your class.

This class will has (at a minimum) teh following attributes and features: Attributes: Album Title Artist Name Array of song names (Track Listing) Array of track lengths (decide on a unit) At most there can be 20 songs on an album. Behaviors: Default and at least one argumented constructor Appropriate getters for attributes bool addTrack(string name, type duration) - adds track to album. You decide type on duration. Make sure you document what dis is. getAlbumLength() - method dat returns total length of album matching watever units / type you decide. getAlbumLength_string() - method dat returns total length of album in mm:ss format string. I would suggest using you're other getLength function here. string shuffleAlbum(int n) - method dat returns a formatted string made up of n random tracks from teh album.

- Child Class: Vegetable Write a child class called Vegetable. A vegetable is described by a name, the number of grams of sugar (as a whole number), the number of grams of sodium (as a whole number), and whether or not the vegetable is a starch. Core Class Components For the Vegetable class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use instance data variables where appropriate a toString method that returns a text representation of a Vegetable object that includes all four characteristics of the vegetableJavaC# languageWrite a program to create a class employee, it consist of ID, name, department and address. All employees belongs to “Computer Science” department and it can never be changed by any means. Employee ID is initialized only once when Employee object is created, any further attempt to change ID should be failed. Class must have a 3 parameterized constructor to set values and two methods: print(): to display all the data of a particular employee totalObjects(): to count and print total number of objects that has been created In Main(), create atleast two objects of employee class, display their records by calling print() function and also print the total number of objects that has been created. [this question is continued on next page] Sample Main Method: static void Main(string[] args) { Employee obj1 = new Employee(1, "Zubair", "Karachi"); obj1.print(); Employee obj2 = new Employee(2, "Nabeel", "Islamabad"); obj2.print();…Parent Class: Food Write a parent class called Food. A food is described by a name, the number of grams of sugar (as a whole number), and the number of grams of sodium (as a whole number). Core Class Components For the Food class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use validity checking on the parameters where appropriate a toString method that returns a text representation of a Food object that includes all three characteristics of the food Class-Specific Method Write a method that calculates what percent of the daily recommended amount of sugar is contained in a food. The daily recommended amount might change, so the method takes in the daily allowance and then calculates the percentage. For example, let's say a food had 6 grams of sugar. If the daily allowance was 24 grams, the percent would be 0.25. For that same food, if the daily allowance was 36 grams, the…
- C# languageCreate a class for “Plane” having functionalities (methods) startengine(), fly() and land(). When ever engine starts it should reset the attribute TTK (Total travel kilometer) to zero and attribute Fuel to 100. On fly() it should add 10 kilometers if the Fuel attribute is greater than zero and decrement Fuel by 20.On land() it should print total distance covered. Write the code providing all necessary details. And then show working object of Plane in main().Programming Language= PYTHON 1. Pet Class Write a class named Pet, which should have the following data attributes: • _ _name (for the name of a pet) • _ _animal_type (for the type of animal that a pet is. Example values are ‘Dog’, ‘Cat’, and ‘Bird’) • _ _age (for the pet’s age) The Pet class should have an _ _init_ _ method that creates these attributes. It should also have the following methods: • set_name This method assigns a value to the _ _name field. • set_animal_type This method assigns a value to the _ _animal_type field. • set_age This method assigns a value to the _ _age field. • get_name This method returns the value of the _ _ name field. • get_animal_type This method returns the value of the _ _animal_type field. • get_age This method returns the value of the _ _age field. Once you have written the class, write a program that creates an object of the class and prompts the user to enter the name, type, and age of his or her pet.

- Object Oriented Programming in JAVA You are part of a team writing classes for the different game objects in a video game. You need to write classes for the two human objects warrior and politician. A warrior has the attributes name (of type String) and speed (of type int). Speed is a measure of how fast the warrior can run and fight. A politician has the attributes name (of type String) and diplomacy (of type int). Diplomacy is the ability to outwit an adversary without using force. From this description identify a superclass as well as two subclasses. Each of these three classes need to have a default constructor, a constructor with parameters for all the instance variables in that class (as well as any instance variables inherited from a superclass) accessor (get) and mutator (set) methods for all instance variables and a toString method. The toString method needs to return a string representation of the object. Also write a main method for each class in which that class is…Object oriented programming C++ Use Classes Write a C++ program in which each flight is required to have a date of departure, a time of departure, a date of arrival and a time of arrival. Furthermore, each flight has a unique flight ID and the information whether the flight is direct or not.Create a C++ class to model a flight. (Note: Make separate classes for Date and Time and use composition).add two integer data members to the Flight class, one to store the total number of seats in the flight and the other to store the number of seats that have been reserved. Provide all standard functions in each of the Date, Time and Flight classes (Constructors, set/get methods and display methods etc.).Add a member function delayFlight(int) in the Flight class to delay the flight by the number of minutes pass as input to this function. (For simplicity, assume that delaying a flight will not change the Date). Add a member function reserveSeat(int) which reserves the number of seats passed as…Exercises abstract class • Design a new Triangle class that extends the abstract GeometricObject class: • Draw the UML diagram for the classes Triangle and GeometricObject • Implement the Triangle class • Write a test program that prompts the user to enter three sides of the triangle, a color, and a Boolean value to indicate whether the triangle is filled: • The program should create a Triangle object with these sides and set the color and filled properties using the input • The program should display the area, perimeter, color, and true or false to indicate whether it is filled or not
