Laboratory 3: Ice Cream!

Download Lab03.zip from ilearn and extract it into your working lab 3 directory

In this lab, you will be writing a complete class from scratch, the IceCreamCone class. You will also write a driver to interact with a user and to test all of the IceCreamCone methods.

Lab:

• Cone
• Ice Cream

o Flavor

o Topping

• Ice Cream Cone

• Driver

Part I: Cone

An ice cream cone has two main components, the flavor of ice cream and the type of cone. Write a Cone class that takes an integer in its constructor. Let a 1 represent a sugar cone, let a 2 represent a waffle cone, and let a 3 represent a cup. It will help to use a private variable in order to keep track of the cone type amongst your methods. Make sure to set an invalid entry to a default cone (the choice of default is up to you). Write a method to return the price of the cone. The sugar cone is $0.59, the waffle cone is $0.79, and the cup is free. Write a toString() method to return a String indicating the type of cone that was selected.

Note: If you need a carriage return in a String, use "\r\n"

Part II: Ice Cream
Download the following files:

• Topping.java
o public double price() //toppings are $0.15 ("no topping" is free)

• Toppings.java //this file has the following public interface:
o public static Toppings getToppings() //singleton design pattern
o public int numToppings() //the number of different toppings
o public String listToppings() //list (and number) available toppingso public Topping getTopping(int index) //1-based

• Flavor.java

• Flavors.java //this file has the following public interface:

o public static Flavors getFlavors() //singleton design pattern
o public int numFlavors() //the number of different flavors
o public String listFlavors() //list (and number) available flavorso public Flavor getFlavor(int index) //1-based

Ice cream has a number of scoops, a flavor, and a topping. Write an IceCream constructor that accepts the number of scoops (up to 3), a Flavor object, and a Topping object. It will help to use private variables in order to keep track of the number of scoops, your flavor, and your topping amongst your methods. Set default values (up to you) if the input is invalid (make sure to protect against null). Write a method to return the price

(each scoop over 1 adds $0.75 to the cost of the ice cream) and a method to return a String listing the ice cream parameters selected.

Part III: Ice Cream Cone

Download the following file:

• Currency.class //this file has the following public interface:
o public static String formatCurrency(double val) //formats the double as a String representing US

currency

It will help to use private variables in order to keep track of your cone and ice cream amongst your methods. Use Currency.class to format the total price of the Ice Cream Cone.

Note: Without using the Currency class, it is possible to get final prices that are not quite correct, such as 3.5300000000000002.

The IceCreamCone is composed of the Cone and the IceCream. Write a constructor that accepts an IceCream

and a Cone (protect against null), a method to return the price (the base price is $1.99 plus any costs

associated with the components), and a method to return a String display of the ice cream cone ordered by the

user.

Part IV: Ice Cream Driver

Download the following file:

• Keyboard.class //this file has the following public interface:
o public static Keyboard getKeyboard() //singleton design patterno public int readInt(String prompt)
o public double readDouble(String prompt)
o public String readString(String prompt)

defensive programming

In addition to main, include the following methods in your driver:

This is

Write a driver to obtain the ice cream cone order from the user. Allow multiple ice cream cones to be ordered,

and keep a

running total

of the price of the ice cream cones. Of course, wait (loop) for the user to input valid

entries. Thus, you are checking for valid entries in the driver and in the constructor of your objects.

, although it results in some code duplication.

1. public static Flavor getFlavorChoice() //look at the methods available in the Flavors class

2. public static Topping getToppingChoice() //look at the methods available in the Toppings class

3. public static int getScoopsChoice()

4. public static Cone getConeChoice()

All of these methods take input from the user (using Keyboard.class) Example output included as a jpg in Lab03 files.
To compile: javac *.java

To run: java IceCreamDriver

You can also run your driver with my input file via: java IceCreamDriver < ice_cream.txt (or by running make.bat)

The five basic components of promotion include advertising, sales promotions, social media, publicity, and personal selling. All five components of the retailer’s promotion mix need to be managed from a total systems perspective.

All non-essential retail businesses are closed due to the COVID-19 lockdown. At some point (hopefully in the near future) we will return to normal and these businesses will reopen.

While these businesses will be receiving financial support from the government, many are going to be in a tight situation, and fighting for every dollar when the doors finally open. So, they will need to rely on sales promotion, publicity, social media and personal selling to succeed. Those that don’t get out of the gate strong may not survive.

Choose one of the following retailers: Hair Cuttery; Hand and Stone Massage; Modell’s; Caesars casino; or Outback Steakhouse.

Describe the best way your retailer choice can use the four promotional components (sales promotion, publicity, social media and personal selling) to be successful when the lockdown is over.

Design and implement a class named Person and its two subclasses named Student and Employee.

Make Faculty and Staff subclasses of Employee.

A person has a name,address, phone number, and email address.

A student has a class status (year 1,year 2,year 3,or year 4).

An employee has an office, salary, and date hired.

Use the Date class from JavaAPI 8 to create an object for date hired.

A faculty member has office hours and a rank.

A staff member has a title.

Override the toString method in each class to display the class name and the person’s name.Design and implement all 5classes.

Write a test program that creates a Person,Student,Employee,Faculty, and Staff, and iinvokes their toString()methods

Carlos and Shannon are sledding down a snow-covered slope that is angled at 12.0° below the horizontal. When sliding on snow, Carlos’s sled has a coefficient of friction μ_k = 0.100; Shannon has a “supersled” with μ_k = 0.0100. Carlos takes off down the slope starting from rest. When Carlos is 4.00 m from the starting point, Shannon starts down the slope from rest.

How far have they traveled when Shannon catches up to Carlos?

How fast is Shannon moving with respect to Carlos as she passes by?

Can anyone fix this code? The code isn't rounding the answer to the nearest whole number like 2.345 should be 2 and 2.546 should be 3 but the round() function isn't working as expected. The round() function is rounding 2.546 to 2 which is incorrect since 4 and below should be rounded to 2 and 5 and above should be rounded to 3.

Here is the code:

#importing xlwt library to write into xls
import xlwt
from xlwt import Workbook

#create a workbook
wb = Workbook()
#create a sheet
sheet = wb.add_sheet('Sheet')

#percentages list
percentages = [23.6, 38.2, 50, 61.8, 78.6, 113, 123.6, 138.2, 161.8]
#add first row
for i in range(len(percentages)):
   sheet.write(0,i+1,str(percentages[i])+'%')

#user input
n = int(input('Enter number of elements: '))
#second row starts from index 1
row=1
print('Enter numbers: ')
for i in range(n):
    #User input
   val = float(input())
   #Add entered value to first column of the row
   sheet.write(row,0,str(val))
   #calculate each percentage
   for j in range(len(percentages)):
       result = (percentages[j]/100)*val
       #write result to sheet by rounding upto 3 decimal points
       sheet.write(row,j+1,str(round(result,3)))
   #increment the row by 1
   row+=1
#save Workbook as xls`
wb.save('percentages.xls')

Thank you so much for anyone who helped!
