Question

Write a class Cylinder that contains information about a cylindrical object.
The Cylinder class must have two instance variables:
self.r is a floating point value describing the radius of the cylinder
self.h is a floating point value describing the height of the cylinder
The Cylinder class should also have a constructor and two methods:
• _init__(self, diameter, height) takes in two parameters other than self,
representing the diameter of the cylinder, and the height, and uses this information to set
up self.r and self.h. Note that to get the radius (self.r) from the diameter, you'll
need to divide by 2.
• get_surface_area(self) returns the surface area of the cylinder, given by the
formula:
A = 2лr² + 2лrh
You should import math and use math.pi to get an accurate value for
get_volume (self) returns the volume of the cylinder, given by the formula:
V = πr²h

An object of the class Timer is used to indicate when a certain amount of time (in seconds) has elapsed, after which it provides a “DING". The required data field is remainingTime which is the number of seconds until the “DING". When a Timer object is constructed, it is set with the desired number of seconds. When the timer "ticks", it is one second closer to the "DING". This is represented with the tick) method. The dingChecko method indicates whether the timer should be "DINGING". Provide the code for the constructor method, and the methods getRemainingTime), tick(), and dingCheck). public class Timer // Methods // Data private int KeuainingTinei }

Construct a Time class containing integer data members seconds, minutes, and hours. Have the class contain two constructors: The first should be a default constructor having the prototype Time(int, int, int), which uses default values of 0 for each data member. The second constructor should accept a long integer representing a total number of seconds and disassemble the long integer into hours, minutes, and seconds. The final member method should display the class data members.

public class Cat { private int age; public Cat (int a) { age = а; } public int getAge() { return a; } } Which of the following best explains why the getAge method will NOT work as intended? The instance variable age should be returned instead of a, which is local to the constructor. The variable age is not declared inside the getAge method. The getAge method should be declared as private. The getAge method should have at least one parameter.

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.
The total cost of a group of items at a grocery store is based on the sum of the individual product prices and the tax (which is 5.75%). Products that are considered “necessities” are not taxed, whereas products that are considered “luxuries” are. The Product class is abstract, and it has a method called getTotalPrice. Your task is to create two subclasses of Product: NecessaryProduct and LuxuryProduct and implement the getTotalPrice method in each of these classes appropriately. Then modify the driver program to instantiate four products (two necessary and two luxury) and store them in the product array, print out each item in the array, and display the total cost of the items. You should not make any changes at all to Product.java, and you should only add to ShoppingTripStartingCode.java. Do not change any code that is already present Example(Cheese and bread are necessities and soda and candy are luxuries)Cheese…

Test this on a successful creation of a Dog object.>>> import dog>>> sugar = dog.Dog('Sugar', 'border collie')>>> sugar.name'Sugar'>>> sugar.breed'border collie' Add a data attribute tricks of type list to each Dog instance and initialize it in __init__ to the empty list. The user does not have to supply a list of tricks when constructing a Dog instance. Make sure that you test this successfully.>>> sugar.tricks[] Write a method teach as part of the class Dog. The method teach should add a passed string parameter to tricks and print a message that the dog knows the trick.>>> sugar.teach('frisbee')Sugar knows frisbee
