An outlet store is having a sale in their Cabin brand sweaters.
There are two different pricing systems depending on if it is a
Cabin brand or not. Tax must be added on after the sweater charge
is computed.
You must have two classes using separate files.
Requirements for Sweater Class
Fields
1. sweater price (in dollars)
2. Boolean to indicate if it is a Cabin brand or not
3. number of sweaters purchased
Methods
1. One 3 parameter constructor- the constructor uses
three parameters representing the sweater price, whether it is a
Cabin Brand or not, and the number of sweaters purchased.
2. Getter and setter for each field
3. getTotalPurchase method
This method must call the appropriate getter member methods where
necessary. Do not access the fields directly.
This method calculates and returns the total amount of the
sweater.
If the sweater is Cabin brand, calculate the discount as
follows;
-If the customer purchases 1 sweater the discount is 20% of the
sweaters price.
-if the customer purchases 2 or more sweaters the discount is
30%
-the customer cannot purchase less than 1 sweater.
-compute the purchase subtotal by subtracting the appropriate
discount from the sweaters price.
Use a tax rate of 7% of the purchase subtotal to compute the sales
tax in dollars. Add the sales tax amount to the purchase subtotal
to determine the total purchase amount.
Return the total purchase amount to the calling code.
Requirements for the SweaterDriver Class
Main method
1. customer must be prompted appropriately
2. All values related to money may include values after
the decimal point. All values displayed to the screen must display
with 2 places after the decimal.
3. The customer must indicate whether the sweater is
Cabin brand or not by typing a single character (y for yes, n for
no) program must accept Upper and lower case, Y,y,N,n.
4. If the sweater is Cabin brand, prompt the customer
to enter the number of Cabin sweaters being purchased.
5. Instantiate a Sweater object using a three parameter
constructor.
Note that the parameter that indicates if the sweater is a Cabin
brand is a Boolean data type.
The customer must type a single character. You will have to use
selection to instantiate a Sweater object with the correct data
type foe this parameter.
6. Display the values in the output by calling the
appropriate method of the Sweater object. The output must line up
at the decimal point as in the sample runs.
Sample runs
1
Enter the price of the sweater: $50.00
Is the swear a Cabin(Y/N)? N
Price of sweater $50.00
Total purchase $53.50
Run 2
Enter the price of the sweater: $60.00
Is the sweater a Cabin(Y/N)? Y
Enter the number of sweaters being purchased: 2
Price of sweater $60.00
Total Purchase $89.88
Run 3
Enter price of sweater: $40.00
Is the sweater a Cabin(Y/N)? Y
Enter the number of sweaters being purchased: 1
Price of sweater $40.00
Total purchase $34.24

Task #1 The while Loop (8 pts) 1. Copy the file DiceSimulation.java as directed by your instructor. Correct syntax errors if any, and improve programming style when necessary (indents, newlines, etc.). DiceSimulation.java is incomplete. Since there is a large part of the program missing, the output will be incorrect if you run DiceSimulation.java. 2. We have declared all the variables. You need to add code to simulate rolling the dice and keeping track of the doubles. Convert the algorithm below into Java code and place it in the main method after the variable declarations, but before the output statements. You will be using several control structures: a while loop and an if-else-if statement nested inside another if statement. Use the indenting of the algorithm to help you decide what is included in the loop, what is included in the if statement, and what isincluded in the nested if-else-if statement. 3. To “roll” the dice, use the nextInt method of the random number generator to generate an integer from 1 to 6. Repeat while the number of dice rolls are less than the number of times the dice should be rolled. Get the value of the first die by “rolling” the first die Get the value of the second die by “rolling” the second die If the value of the first die is the same as the value of the second die If value of first die is 1 Increment the number of times snake eyes were rolled Else if value of the first die is 2 Increment the number of times twos were rolled Else if value of the first die is 3 Increment the number of times threes were rolled Else if value of the first die is 4 Increment the number of times fours were rolled Else if value of the first die is 5 Increment the number of times fives were rolled Else if value of the first die is 6 Increment the number of times sixes were rolled Page 3 of 3 Increment the number of times the dice were rolled 4. Compile and run. You should get numbers that are somewhat close to 278 for each of the different pairs of doubles. Run it several times. You should get different results than the first time, but again it should be somewhat close to 278. Task #2 Using Other Types of Loops: do-while (4 pts) 1. Change the while loop to a do-while loop. 2. Make other necessary changes to save your work as new file named DiceSimulation_Do.java. 3. Compile and run. You should get the same results as at Task #1. Task #3 Using Other Types of Loops: for (4 pts) 1. Change the do-while loop to a for loop. 2. Make other necessary changes to save your work as new file named DiceSimulation_For.java. 3. Compile and run. You should get the same results as at Task #1.

Rock, Paper, Scissors
Introduction
In this assignment you will create a program that will simulate the popular children’s game “Rock, Paper, Scissors”; using only Boolean logic and practice using the for-loop and logical operators as well as continue getting used to data of various types.
Skills: string input/output, data types, logical operators, and control structures
Rock-Paper-Scissors
Rock-Paper-Scissors is a game where two players, on the count of 3, show the rock/paper/scissors symbol with their hand. Rock smashes scissors, scissors cuts paper, and paper covers rock:
Once both players have played valid gestures, there are two ways to determine the winner: one using string comparison and Boolean logic and the other using modular arithmetic; you’ll write a solution using both approaches. For this assignment, only “rock”, “paper”, and “scissors” are considered valid gestures.
Definitions:
1. Valid game: a game in which both players select a valid gesture
2. Invalid game: a game in which a player selects a gesture that is not “rock”, “paper”, or “scissors”. (HINT: DeMorgan’s law will help negation of valid game)
main.cpp
Your program should use a for-loop to play 7 consecutive games (must be a variable) of Rock-PaperScissors determining the winner using only the four decision statements. For each game, your program should:
1) Prompt Player 1 for their selection. The inputs for each game are given below. a. If Player 1 enters an invalid selection you should update the count of invalid games and then begin a new game.
2) Prompt Player 2 for their selection. The inputs for each game are given below.
a) If Player 2 enters an invalid selection you should update the count of invalid games and then begin a new game.
3) If both players have selected a valid gesture determine the winner using string comparison and if/else logic.
4) For each valid game completed, update the count of the number of wins by Player 1, the number of wins by Player 2, or the number of ties as needed.
Test input:
• Game 1: Player one plays “scissors” and Player 2 plays “paper”
• Game 2: Player 1 plays “paper” and Player 2 plays “papers”
• Game 3: Player 1 plays “rock” and Player 2 plays “rock”
• Game 4: Player 1 plays “rocks”
• Game 5: Player 1 play “paper” and Player 2 plays “scissors”
• Game 6: Player 1 plays” scissors” and Player 2 plays “rock”
• Game 7: “Player 1 plays “paper” and Player 2 plays “rock”
Test Run: Your code should look exactly like the one below
Player 1 Enter Selection: scissors
Player 2 Enter Selection: paper
Player 1 Enter Selection: paper
Player 2 Enter Selection: papers
Player 1 Enter Selection: rock
Player 2 Enter Selection: rock
Player 1 Enter Selection: rocks
Player 1 Enter Selection: paper
Player 2 Enter Selection: scissors
Player 1 Enter Selection: scissors
Player 2 Enter Selection: rock
Player 1 Enter Selection: paper
Player 2Enter Selection: rock
