Assignment 2 Make a new class called Buffet which posses all the methods and attributes of the Restaurant class. In addition, define a new attribute called people_served that sets at 0 for each newly constructed object. Also, make a method called ppl() that gets the number of people served on each table and updates the people_served attribute accordingly. Then prints the total number of people served so far. Construct a new buffet object with Milano as name and Italian as cuisine type, then call the order() method with an order size of 10 meals as well as the ppl) method with a table size of 6 people.

In this exercise, you are going to build on your Circleclass from the previous exercise. You are going to add 2 method, areaDifference and perimeterDifference. Both methods take a doubleradius of a second circle and return the difference from the current circle. For example, if you create a Circle object with a radius of 4 and call areaDifference(3), you will return the diffence between the area of a circle with radius 4 and the area of a circle with a radius of 3. perimeterDifferencewould be the same. Make sure you create at least one Circle and test and print the results of your methods. in java

These two pictures are my resource and driver classes. Please, help me with the error in my resource class. I want my resource class to have getName, getSalary, getThePercentageThatTheEmployeeWantToRaise, and calculateTheNewSalary methods. For my driver class, I want the driver class to ask the user to input their name, salary, how much they want to raise, and print out their new salary.
In Python Make a new class called Electric_Car which posses all the methods and attributes of the Car class. In addition set a new attribute called charge_count that starts from 0 for any newly constructed electric car. Write a new method called charge() that each time we call it for a given electric car, updates the charge_count by adding 1 unit. Now construct a new electric car instance with following attributes: Make: Tesla; Model: s; Year: 2018. Call the trip() method to update odometer with a trip of 200 miles. Also call the charge() method to update the charge count twice.
I have provided you with 3 interfaces (HasLegs, HasWings, and BreathesUnderwater) and a Tester class. I want you to create 6 new classes: • 2 that implement HasLegs • 2 that implement HasWings • 2 that implement BreathesUnderwater For each of the classes, you will have to implement the methods that the interface dictates. In addition, override toString so that it prints out a simple message describing what the object is. See the example output of my implementation below for an idea how to do that. The Tester class creates 3 ArrayLists, one for each interface. It also loops through each ArrayList and prints out its contents using toString and the interface methods. In between those two chunks of code, you’ll see a //TODO: comment. It is there that I want you to create one object for each of the 6 classes you created and add that object to the appropriate ArrayList. Once you have done all that, you should be able to run your program and see output like the following: I am a table. I have…
Redefine the equals method of the class Date (Display 4.13) so that it hasa parameter of type Object and follows the other guidelines we gave for anequals method. (Remember, you should use getClass(), not instanceof.)
Take the tax program from the last homework assignment and implement it using classes and objects instead. To do so, create a class definition for a class called Customer with attributes income and tax. It should also have a set method for income, and a calcTax() method to assign tax and return it. As a reminder, the tax is calculated as follows: Income Tax Due $0 - $50,000 5% $50,000-$100,000 $2,500 + 10% of (income > $50,000) > $100,000 $7,500 + 15% of (income > $100,000) Create a Customer object in main, have the user enter the income and assign this to the income variable of the Customer object, and then call the calcTax() method for the Customer object and print the tax due.
Please in pyth coding with correct indentation 4a) Given that you have a Liquid class that can be initialized with any amount of gallons, liters, ounces, etc, write the first line of the method that will allow you to add together two Liquid objects using operator overloading. Again, write ONLY the first line (method definition) – you do NOT have to write the entire method. 4b) Given that you have L1 and L2 which are instances of the Liquid class, write a line of code that uses operator overloading to add them together and assign the result to L3.
In method cook() of the CherryPie class, perform the following tasks: Increment class attribute total_pies. Assign instance attribute num_cherries with the value of parameter cherries_used. Output 'One cherry pie made with ', followed by the value of instance attribute num_cherries, and ' cherries'.
Create three more classes that inherit from Crew. Unless noted otherwise, each of these classes has the same instance variables as Crew, so don’t override the __init__ method. Engineer(Crew): The only method that should be overridden in the Engineer class is the repair method. repair(self, ship) takes in self and a Starship object, and represents an attempt by the Engineer to repair a section of the ship. If the engineer’s current location is damaged (that is, ship.damaged for the location is True), then the value for that key should be changed to False, and a message should print out of the form: <Name> fixed the damage to <Location>. If the engineer’s current location is NOT damaged, then instead the method should print a message of the form: <Location> isn’t damaged. Captain(Crew): The only method that should be overridden in the Captain class is the fire_lasers method. This method represents an attempt by the captain to fire lasers…

(1) Add an __init__ method to the Widget class below. Each object of type Widget should have an instance variable called name and an instance variable called cost that represents a cost in dollars; those values are passed in when an object of type Widget is initialized. (2) Add a method to class Widget called is_cheap that returns True if the cost is less than $10, and False otherwise. (3) Add proper doctrings along with two examples for each method. You may use the Sample Usage code given below in your work.
