a constructor that takes in an int, a string, and a double, constructor will assign them to the ID, name, and Averageinstance variables, then a no-argument (zero-parameter) constructor that will set the ID to the name to “No name assigned” and the Average to –1.0. With an accessor method for the name variable and a mutator method for the average variable. a toString() method that will display all three instance variables on a single line, with a " | " between each one. and then an equals() method that returns true only if all three instance variables are equal

Create an automobile class that will be used by a dealership as a vehicle inventory program. The following attributes should be present in your automobile class: private string make private string model private string color private int year private int mileage Your program should have appropriate methods such as: default constructor parameterized constructor add a new vehicle method list vehicle information (return string array) remove a vehicle method update vehicle attributes method. All methods should include try..catch constructs. Except as noted all methods should return a success or failure message (failure message defined in "catch"). Create an additional class to call your automobile class (e.g., Main or AutomobileInventory). Include a try..catch construct and print it to the console. Call automobile class with parameterized constructor (e.g., "make, model, color, year, mileage"). Then call the method to list the values. Loop through the array and print to the screen.…

Problem Class In this exercise, you are going to create the Problem class. The Problem class is used to help simulate a math fact, for example: 2+5= Your class needs to contain two constructors, one that takes String, int, int that represents the operator sign(+,-, *, or /), the minimum, and maximum values for the number range, and a second constructor that takes only a String that represents the operator sign. For the second constructor, the minimum should default to zero and the maximum to ten. Your Problem object should generate 2 random integers between the minimum and maximum values (inclusively). Each Problem object should only have one set of numbers that do not change. While you may include additional helper methods, two methods need to be available to the user. The first is the answer method that should return a double that represents the answer to the problem. The second is the toString that should return a String that represents the problem. The format should be: number…
1. Part 1: A point in the x-y plane is represented by its x-coordinate and y-coordinate. Design the class Point that can store and process a point in the x-y plane. Your class should contains the following methods. Default constructor without parameters that initializes the private data member to the suitable values Constructor with parameters sets the values of the instance variables to the values of the parameter. Accessor methods that return the values of the x-axis and y-axis. setPoint method which set the values of x-axis and y-axis makeCopy method that make a copy of a received object of type Point. getCopy method that returns a copy of the current object toString method that returns the object string isEqual that returns true if the current object is equal to the received object of type point distance, which receives two objects of type Point and returns the distance

The Hal9000 has one constructor which takes a String parameter of a name of the crew member it is interacting with. It has methods: public String getName() which gets the name public void setName(String newName) which sets a new name public String greet() which returns a string consisting of "Greetings, name" where name is the name supplied in the constructor. public String reportStatus() which returns a string consisting of "All systems are operating normally, name" where name is the name supplied in the constructor. public String execute(String command) which returns a string consisting of "I am sorry, name. I can't " + command where name is the name supplied in the constructor and command is the parameter.

in C# languageDesign a Book class that holds the title, author’s name, and price of the book. Books’s constructor shouldinitialize all of these data members except the price which is set to 500/-. Create a display method thatdisplays all fields.All Books are priced at 500/- unless they are PopularBooks. The PopularBooks subclass replaces theBookprice and sets each Book’s price to 50,000/- through PopularBooks construcor. Override the displaymethod to display all fields.Write a Main () method that declares an array of five Book objects. Ask the user to enter the title andauthor for each of the 5 Books. Consider the Book to be a PopularBook if the author is one of the following:Khaled Hosseini, Oscar Wilde, or Rembrandt. Display the five Books’ details.
PYTHON: Define the Artist class with a constructor to initialize an artist's information and a print_info() method. The constructor should by default initialize the artist's name to "None" and the years of birth and death to 0. print_info() should display Artist Name, born XXXX if the year of death is -1 or Artist Name (XXXX-YYYY) otherwise. Define the Artwork class with a constructor to initialize an artwork's information and a print_info() method. The constructor should by default initialize the title to "None", the year created to 0, and the artist to use the Artist default constructor parameter values. Ex: If the input is: Pablo Picasso 1881 1973 Three Musicians 1921 the output is: Artist: Pablo Picasso (1881-1973) Title: Three Musicians, 1921 If the input is: Brice Marden 1938 -1 Distant Muses 2000 the output is: Artist: Brice Marden, born 1938 Title: Distant Muses, 2000 I have the code but I am getting errors that I can't seem to get rid of any suggestions would be appreciated
