For this question, use the class shown below: public abstract class vehicle { protected double speedMPH; protected double hoursTraveled; } abstract boolean travel (double time); public double getDistanceTraveled() { return speed * hours Traveled; } Define a subclass of the Vehicle class called Train. Train needs to contain the following members: • A new variable called maxCargo, an integer representing the tonnage the train is capable of carrying. • A constructor that takes two parameters, speed and cargoLimit, and sets the speedMPH and maxCargo variables accordingly (hoursTraveled should be set to 0). • A constructor that takes no parameters. In this constructor, set speedMPH to 30, maxCargo to 50, and hoursTraveled to 0. Override the travel method to represent the time the train spends

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

Implement the Seller class as a derived class of Person class. Create the seller.h and seller.cppfiles for this class. The Seller class contains additional data members that hold a seller’s:o average star rating received from the buyers, ando total number of items sold.These data should be accessible by its derived classes. (should these data be private, public, orprotected?) The following methods are included in the seller class:• A default constructor and a copy constructor• A constructor that receives all of the data for a seller.(for the constructors, make sure to call the base class constructor as appropriate)• Appropriate get and set functions for the new data in this class• print() – overrides the base class print() to print the base class data and print all additionalseller data with appropriate messages. Make sure to call the base class print to print thebase class data.• read() – overrides the base class read() to read the base class data and reads all additionalseller data…

Create abstract class Pet , which is the abstract superclass of all animals. Declare a integer attribute called legs, which records the number of legs for this animal. Define a constructor that initializes the legs attribute. Declare an abstract method eat. Declare a concrete method walk that prints out something about how the animals walks (include the number of legs). Create the Dog class. The Dog class extends the Pet class. This class must include a String attribute to store the name and food of the pet Define a default constructor that calls the superclass constructor to specify that all dogs have 4 legs and name. override the eat and walk method. Create the Cat class that extends Pet. This class must include a String attribute to store the name of the pet, and a string to save food . Define a constructor that takes one String parameter that specifies the cat's name and food. This constructor must also call the superclass constructor to specify that all cats have four legs.…

Write anapplication that tracks all new construction loans. The application also must calculate the totalamount owed at the due date (original loan amount + loan fee). The application should includethe following classes:•• Loan—A public abstract class that implements the LoanConstants interface. A Loan includes aloan number, customer last name, amount of loan, interest rate, and term. The constructor requiresdata for each of the fields except interest rate. Do not allow loan amounts greater than R100,000.Force any loan term that is not one of the three defined in the LoanConstants class to a short-term,1-year loan.

Person and Customer Classes Write a class named (Person) with data attributes for a person’s name, address, and telephone number. Provide accessors/getters and mutators/setters for each attribute. Write a displayPerson() to print out the attributes of the Person. Next, write a class named (Customer) that is a subclass of the (Person) class. The (Customer) class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Provide accessors/getters and mutators/setters for each attribute. Write a display customer() to print out the attributes of the Customer. Demonstrate an instance of the (Customer) class in a simple program.
