in python language In this task, we’re going to be simulating an email message. Some of the logic hasbeen filled out for you in the email.py file.● Open the file called email.py.● Create a class definition for an Email which has four variables:has_been_read, email_contents, is_spam and from_address.● The constructor should initialise the sender’s email address.● The constructor should also initialise has_been_read and is_spam to false.● Create a function in this class called mark_as_read which should changehas_been_read to true.● Create a function in this class called mark_as_spam which should changeis_spam to true.● Create a list called inbox to store all emails (note that you can have a list ofobjects).● Then create the following methods:○ add_email - which takes in the contents and email address from thereceived email to make a new Email object.○ get_count - returns the number of messages in the store.○ get_email - returns the contents of an email in the list. For this, allowthe…
I am having trouble with doing this code on Python: Develop the Car class by creating an attribute purchase_price (type int) and the method print_info() that outputs the car's information. Ex: If the input is: 2011 18000 2018 where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, then print_info() outputs: Car's information: Model year: 2011 Purchase price: 18000 Current value: 5770 Note: print_info() should use three spaces for indentation.
Hi, I am making a elevator simulation and I need help in making the passenger classes using polymorphism. Any help is appreciated. There are 4 types of passengers in the system:Standard: This is the most common type of passenger and has a request percentage of 70%. Standard passengers have no special requirements.VIP: This type of passenger has a request percentage of 10%. VIP passengers are given priority and are more likely to be picked up by express elevators.Freight: This type of passenger has a request percentage of 15%. Freight passengers have large items that need to be transported and are more likely to be picked up by freight elevators.Glass: This type of passenger has a request percentage of 5%. Glass passengers have fragile items that need to be transported and are more likely to be picked up by glass elevators. This is what I have so far // Passenger abstract classpublic abstract class Passenger { protected String type; protected int requestPercentage; public…
If you fly in economy class, then you can be promoted to businessclass, especially if you have a gold airline card for privateflights. If you do not have a gold card, you can "reset" fromflight if the plane is full or you are late for check-in. All thesethe conditions are shown in the diagram below. Note that all statements(operators) are numbered. You run 3 tests:Test 1 - Gold card holder upgraded to business classTest 2 - Passenger without gold card remains in economy classTest 3 - Passenger who was "thrown" off the flightWhat is the statement coverage of these three tests?A. 60%B. 70%C. 80%D. 90%
The usual deﬁnition of a palindrome is a word that reads the same both forward and backward, like “otto” and “palindromeemordnilap.” An alternative way to deﬁne a property like this is to specify a way of testing for the property. For example, we might say, “a single letter is a palindrome, and a two-letter word is a palindrome if the letters are the same, and any other word is a palindrome if the ﬁrst letter is the same as the last and the middle is a palindrome.” Write a recursive method named isPalindrome that takes a String and that returns a boolean indicating whether the word is a palindrome or not.
Which of the following cases is most like the strategy pattern? A. If you have an interface called Duck, and have many ducks that implement the duck interface. All of these ducks must have the behaviour “quack” but for some ducks, like a Mallard, this must result in a quack, where for a rubber duck it must result in a squeak. We decide to delegate the quack method to another interface, which can be implemented either in a concrete class that returns a quack or a concrete class that returns a squeak. B. If we have an interface called Duck. We need to give an object to a user that can quack like a duck. All we have is Turkeys. We create a special class that implements the duck interface, and to implement the quack method we simply call the turkey’s gobble method. C. None of these are like the strategy pattern. D. We have a large collection of Ducks. We want to look at them one by one and hear them quack. We write a piece of code that iterates through them all, and as we encounter…
Programing language is Java. Define a class Person that represents a person. People have a name, an age, anda phone number. Since people always have a name and an age, your class shouldhave a constructor that has those as parameters. Define a toString() method whichdisplays all of the relevant information using a format like this: “Jim Lahey - Age 57- Phone 9025555555”.

Which of the following is correct about a Package object in the object-oriented software design? Select one: O a. A Package object's attributes should always be made public and directly accessible. O b. A Package object contains a set of attributes only. O c. A Family Package object contains a set of methods only. O d. A Package object is one instance of its class.
