Add 2 constructors to the Course class. One that takes no arguments and initializes the data to all 0’s and “” (empty strings). And one constructor that takes all 4 arguments, one argument for each property and then sets the properties to these arguments that are passed in. Lastly change the main to use these new Constructors. You will not need to call the set functions any more, but do not remove the set functions from your class. Main Code à Course c1; c1 = new Course(323, “Intro to Php”, “Intro to Php Programming”, 4); c1.display(); Problem #2: Do the same as above for the Account class.

The dealership sells different types of vehicles: cars and trucks. All vehicles have a make, model, and year. However, a truck has an additional attribute - maximum load capacity (in pounds). Create a class named Vehicle with the following attributes: make, model, and year. Include the following methods: display_info(): This method should print all these details in a formatted string. get_age(): This method should calculate and return the age of the vehicle based on the current year. Tip: You will need to import functionality from the datetime module to do this. Create a class named Truck that inherits from the Vehicle class. This class should have an additional attribute, max_load, which represents the maximum load capacity of the truck. Include the following methods: display_info(): This method should override the method from Vehicle, and when it's called, it should display the truck's make, model, year, and maximum load capacity. can_carry(weight): This method should take a…
Using OOP and functions, create a program that allows a user to customize his/her online game character.The program should allow the user to customize two (2) characters, use objects to create the two characters.The program should allow the user to customize the following characteristics: Class, Weapon, and Skill. Use the functions declared within the class to customize the mentioned parameters. Use user defined functions, for example setClass(), setWeapon, and setSkill. · For class the user may choose from Knight, Wizard, or Archer. · For weapon the user may choose from Sword, Wand, and Bow. · For skill the user may choose from Bash, Fire Ball, and Arrow Charge. After customizing the two characters, a summary of the created characters must be printed. All invalid inputs must prompt the user that the input was invalid and should not terminate the program. You may either repeat the process or repeat where the invalid input was made.
Create a class named Person that holds the following fields: two String objectsfor the person’s first and last name and a LocalDate object for the person’sbirthdate. Create a class named Couple that contains two Person objects. Create aclass named Wedding for a wedding planner that includes the date of the wedding,the names of the Couple being married, and a String for the location. Provideconstructors for each class that accept parameters for each field, and provide getmethods for each field. Then write a program that creates two Wedding objectsand in turn passes each to a method that displays all the details. Save the files asPerson.java, Couple.java, Wedding.java, and TestWedding.java.
Customer This class should now implement the Comparable interface. Customer instances should be ordered by their last name, then first name, and finally the name of their associated building. toString() - Add this method that returns a String with the following format: <lastName>, <firstName> Reading This class should now implement the Comparable interface. Reading instances should be ordered by their timestamp. XmlHandler The following methods should be updated: startElement() - The handler logic should be modified such that it can now create and associate Customer, Building, Room, Device, and Reading objects. endElement() - Modify this method such that the current customer instance is added to the ArrayList of customers when a closing customer element is encountered.

Javascript toggleCommentSection function The function toggleCommentSection should exist. The function toggleCommentSection should return undefined if not passed a parameter. The function toggleCommentSection should return null if passed a parameter that does not match a post ID. The function toggleCommentSection should select and return the correct section element. The function toggleCommentSection should toggle the 'hide' class on the section The following are requirements of the function toggleCommentSection: element.toggleCommentSection a. Receives a postId as the parameter b. Selects the section element with the data-post-id attribute equal to the postId received as a parameter c. Use code to verify the section exists before attempting to access the classList property d. At this point in your code, the section will not exist. You can create one to test if desired. e. Toggles the class 'hide' on the section element f. Return the section element Here is what I have so far:…
Book Donation App Create a book-app directory. The app can be used to manage book donations and track donors and books. The catalog is implemented using the following classes: 1. The app should have donors-repo.js to maintain the list of donors and allow adding, updating, and deleting donors. The donor object has donorID, firstName, lastName, and email properties. This module should implement the following functions: • getDonor(donorId): returns a donor by id. • addDonor(donor): adds a donor to the list of donors; donorID should be autoassigned a random number. • updateDonor(donor): updates the donor having the matching donorID. • deleteDonor(donorID): delete the donor with donorID from the list of donors, only if they are not associated with any books. 2. The app should have books-repo.js to maintain the list of donated books and allow adding, updating, and deleting books. The book object has bookID, title, authors, and donorID properties. • donorID references the book’s donor. This…

Plagarism contents will downvote List any three functions of I/O interface.
Three data members: length, width, and height. All data members are of type Distance. Two overloaded constructors: one that takes no argument and the other that takes three arguments. Zero argument constructor initializes data members from 0 whereas three argument constructor initializes data members from the passed arguments. At least one of the constructors should use an initializer list. A copy constructor. Three getters and three setters corresponding to three data members. A member function named volume that returns the volume of a Box object, i.e., length*width*height. Three member functions named greaterThan, lessThan and equalTo to compare two Box objects based on their volume. Each function must return a Boolean value. A static data member count(int) which is used to count Box objects active at any time. A getter for count. The class must contain a few constant functions (decide which of the above functions are good candidates for that) By using c++
