3. a. Create a class named Circle with fields named radius, area and diameter. Include methods names setRadius(), getRadius(), computeDiameter() which computes a circles's diameter and computeArea which computes a circle's area. The diameter of a circle is twice its radius and the area is 3.14 multiplied by the square of the radius. b. Create a class named TestCircle whose main() declares three Circle objects. Using the setRadius() method, assign one circle a small radius value. Assign another circle a larger radius value and assign the third circle a radius of 1. Call computeDiameter() and computeArea() for each circle and display the results.

Create a class named Shape with a function that prints "This is a shape". Create another class named Polygon inheriting the Shape class with the same function that prints "Polygon is a shape". Create two other classes named Rectangle and Triangle having the same function which prints "Rectangle is a polygon" and "Triangle is a polygon" respectively. Again, make another class named Square having the same function which prints "Square is a rectangle".Now, try calling the function by the object of each of these classes.Please code C++

Python Program: Write a program which controls a metro train and that keeps track of stations and who gets on and off. Design and implement a class called train, which has at least the following: At least the following attributes (you can include others): metroID stationNum which keeps track of the station that the train is at. iii. direction which keeps track of the direction the train is travelling in. passTotal which keeps track of the number of passengers currently on the train. A default constructor which sets the metroID to a random number between 1 and 1000, the station number to 0, the direction (int), and the passTotal to 0 (train is empty). A constructor with one parameter; the parameter is the metro id. The constructor assigns the passed integer to the metroID attribute; the rest of the attributes are set as described in the default constructor. Accessor methods for each attributes. Mutator methods for each attributes. nextStation(int lastStation) which determines…

2019 AP® COMPUTER SCIENCE A FREE-RESPONSE QUESTIONS 2. This question involves the implementation of a fitness tracking system that is represented by the StepTracker class. A StepTracker object is created with a parameter that defines the minimum number of steps that must be taken for a day to be considered active. The StepTracker class provides a constructor and the following methods. addDailySteps, which accumulates information about steps, in readings taken once per day activeDays, which returns the number of active days averageSteps, which returns the average number of steps per day, calculated by dividing the total number of steps taken by the number of days tracked The following table contains a sample code execution sequence and the corresponding results. Statements and Expressions Value Returned Comment (blank if no value) StepTracker tr StepTracker(10000); Days with at least 10,000 steps are considered active.

1. Design a new Triangle class that extends the abstract GeometricObject 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 following classes: Polygon numSide: int /* constructor */ /* accessor-mutator */ + area (): double + perimeter (): double Triangle sideA: double sideB: double sidec: double /* constructor */ /* accessor-mutator */ + area () : double + perimeter (): double Create an object for Triangle class and invoke area and perimeter method. Input Format Take triangle sides (sideA,sideB,sideC) as input from user. Constraints For Triangle, sideB+sideC > sideA

Language is Java Write a Clothing class with the following attributes: color (e.g., "blue", "green", "orange") displayName (e.g., "Doctor Who hoodie", "slacks") price (e.g., 19.99, 7) Include only one constructor. It should have parameters for each of the attributes and set their values. Additionally, include getters and setters for each of the attributes. Add a driver, name it Purchases, and create 2 Clothing objects. Finally, print out some information about both objects (i.e., print the information from some or all of the getters). For example, if you created a Clothing object whose color was blue, whose display name was work trousers, for a price of 27.99, you could use the getters to print something like this:These work trousers are blue and cost $27.99.Don't hardcode the print statement for full credit, you must use the getters

A constructor that creates a circle with the specified x, y, and radius. A method getArea() that returns the area of the circle. A method getPerimeter() that returns the perimeter of the circle. A method contains(double x, double y) that returns true if the specified point (x, y) is inside this circle. See Figure 10.14(a). A method contains(Circle2D circle) that returns true if the specified circle is inside this circle. See Figure 10.14(b). A method overlaps(Circle2D circle) that returns true if the specified circle overlaps with this circle. See the figure below. (a) (b) (c) Figure 10.14 (a) A point is inside the circle.

Create a base class called “Animal” which has two (2) class fields. The first field holds an integer “IDtag” for a number that a zoo uses to catalogue their animals and the second field holds a string called “species.”From the Animal class, derive two (2) classes. One is called “Bird” and the other “Reptile”. E.g. Species could be (for the Bird class) ostrich, dove, chicken etc. and (for the Reptile class) lizard, snake, bearded dragon etc.The Bird class has an additional class field called “colour” which holds the colour of the birds feathers (int – 1=grey, 2=white, 3=black). The reptile class has an additional class field called “bloodTemp” which hold the reptile’s temperature of their blood (double).You need to instantiate two (2) objects. The bird object will be called “brd” and the reptile object called “rept.”Input values for the bird’s IDtag, species and feather colour (int) and for the reptile’s IDtag number, species and bloodTemp. Override the Animal class’s input and output…
