ASSIGNMENT 4 COMP-202

ASSIGNMENT 4
COMP-202
Please read the entire PDF before starting. You must do this assignment individually.
It is very important that you follow the directions as closely as possible. The directions, while
perhaps tedious, are designed to make it as easy as possible for the TAs to mark the assignments by letting
them run your assignment, in some cases through automated tests. While these tests will never be used to
determine your entire grade, they speed up the process significantly, which allows the TAs to provide better
feedback and not waste time on administrative details. Plus, if the TA is in a good mood while he or she is
grading, then that increases the chance of them giving out partial marks. :)
Up to 30% can be removed for bad indentation of your code as well as omitting comments, or poor coding
structure.
To get full marks, you must:
• Follow all directions below
– In particular, make sure that all classes and method names are spelled and capitalized exactly
as described in this document. Otherwise, you will receive a 50% penalty.
• Make sure that your code compiles
– Non-compiling code will receive a 0.
• Write your name and student ID as a comment in all .java files you hand in
• Indent your code properly
• Name your variables appropriately
– The purpose of each variable should be obvious from the name
• Comment your work
– A comment every line is not needed, but there should be enough comments to fully understand
your program

Part 1 (0 points): Warm-up
Do NOT submit this part, as it will not be graded. However, doing these exercises might help you to do the
second part of the assignment, which will be graded. If you have difficulties with the questions of Part 1, then
we suggest that you consult the TAs during their office hours; they can help you and work with you through
the warm-up questions. You are responsible for knowing all of the material in these questions.
Warm-up Question 1 (0 points)
Write a method longestSubArray that takes as input an array of integer arrays (i.e. a multi-dimensional
array) and returns the length of the longest sub-array. For example, if the input is: int[][] arr=
{{1,2,1},{8,6}}; then longestSubArray should return 3.
Warm-up Question 2 (0 points)
Write a method subArraySame that takes as input an array of integer arrays (i.e. a multi-dimensional
array) and checks if all of the numbers in each ‘sub-array’ are the same. For example, if the input is:
int[][] arr= {{1,1,1},{6,6}}; then subArraySame should return true and if the input is: int[][]
arr= {{1,6,1},{6,6}}; then subArraySame should return false.
Warm-up Question 3 (0 points)
Write a method largestAverage that takes as input an array of double arrays (i.e. a multi-dimensional
array) and returns the double array with the largest average value. For example, if the input is:
double[][] arr= {{1.5,2.3,5.7},{12.5,-50.25}}; then largestAverage should return the array
{1.5, 2.3, 5.7} (as the average value is 3.17).
Warm-up Question 4 (0 points)
Write a class describing a Cat object. A cat has the following attributes: a name (String), a breed
(String), an age (int) and a mood (String). The mood of a cat can be one of the following: sleepy,
hungry, angry, happy, crazy. The cat constructor takes as input a String and sets that value to
be the breed. The Cat class also contains a method called talk(). This method takes no input and
returns nothing. Depending on the mood of the cat, it prints something different. If the cat’s mood is
sleepy, it prints meow. If the mood is hungry, it prints RAWR!. If the cat is angry, it prints hsssss. If
the cat is happy it prints purrrr. If the cat is crazy, it prints a String of 10 gibberish characters (e.g.
raseagafqa).
The cat attributes are all private. Each one has a corresponding public get method (ie: getName(),
getMood(), etc.) which returns the value of the attribute. All but the breed also have a public set
method (ie: setName(), setMood(), etc.) which takes as input a value of the type of the attribute and
sets the attribute to that value. Be sure that only valid mood sets are permitted. (ie, a cat’s mood can
only be one of five things). There is no setBreed() method because the breed of a cat is set at birth and
cannot change.
Test your class in another file which contains only a main method. Test all methods to make sure they
work as expected.
Warm-up Question 5 (0 points)
Using the Cat type defined in the previous question, create a Cat[] of size 5. Create 5 Cat objects and
put them all into the array. Then use a loop to have all the Cat objects meow.

Warm-up Question 6 (0 points)
Write a class Vector. A Vector should consist of three private properties of type double: x, y, and
z. You should add to your class a constructor which takes as input 3 doubles. These doubles should
be assigned to x, y, and z. You should then write methods getX(), getY(), getZ(), setX(), setY(),
and setZ() which allow you to get and set the values of the vector. Should this method be static or
non-static?
Warm-up Question 7 (0 points)
Add to your Vector class a method calculateMagnitude which returns a double representing the
magnitude of the vector. Should this method be static or non-static? The magnitude can be computed
by taking:
magnitude =
p
x
2 + y
2 + z
2
Warm-up Question 8 (0 points)
Write a method scalarMultiply which takes as input a double[], and a double scale, and returns
void. The method should modify the input array by multiplying each value in the array by scale.
Should this method be static or non-static?
Warm-up Question 9 (0 points)
Write a method deleteElement which takes as input an int[] and an int target and deletes all
occurrences of target from the array. By “delete” we mean create a new array (of smaller size) which
has the same values as the old array but without any occurrences of target. The method should return
the new int[]. Question to consider: Why is it that we have to return an array and can’t simply change
the input parameter array like in the previous question? Should these methods be static or non-static?
Warm-up Question 10 (0 points)
Write the same method, except this time it should take as input a String[] and a String. What is
different about this than the previous method? (Hint: Remember that String is a reference type.)

Part 2
The questions in this part of the assignment will be graded.
Question 1: Game of Life (60 points)
For this question, you will have to write a Java program that implements a simple version of Conway’s
Game Of Life (https://en.wikipedia.org/wiki/Conway\%27s_Game_of_Life)
This is a zero-player game, which means that it is completely determined by the initial state provided.
For our purpose, we will represent the universe of the Game of Life as a finite rectangular two-dimensional
array. Each element denotes a cell in the universe: if the cell is alive the value of the element is 1, if the
cell is dead the value of the element is 0. Whether a cell is alive or dead in the next generation of the
universe depends on its relation with its neighboring cells (the cells that are horizontally, vertically, or
diagonally adjacent to it). The next generation of cell is determined by the following rules:
• Any live cell with fewer than two live neighbors dies, as if caused by under population.
• Any live cell with two or three live neighbors lives on to the next generation.
• Any live cell with more than three live neighbors dies, as if caused by overpopulation.
• Any dead cell with exactly three live neighbors becomes a live cell, as if caused by reproduction.
In this question, you will implement a method that will allow you to display a given number of generations
of a specified universe.
To complete this task, you will need to implement all the methods listed below. All the code for this
question must be placed in a file named GameOfLife.java. Note that you are free to write more methods
if they help the design or readability of your code.
Note, that you are not required to write a main method for this question. Use the main method to test
all your methods while writing the program. When you hand in your assignment though, make sure
that your main method is empty.
1a) Method to check whether a 2D array represents a valid universe
Write a method isValidUniverse which takes as input a two-dimensional array of integers. The method
should return true if such array is a valid representation of a universe, false otherwise. For the purpose
of this assignment, we consider a two-dimensional array to be a valid representation of a universe if it is
rectangular (i.e. all its sub-arrays are of the same size) and all the elements of its sub-arrays are either
0s or 1s.
For example, consider the following two-dimensional arrays:
int[][] a = {{0,0}, {1,0}, {1,0}};
int[][] b = {{0,0,0}, {1,1}, {0}};
int[][] c = {{1,2}, {3,4}};
int[][] d = {{1,1}, {1,1}};
Then:
• isValidUniverse(a) returns true.
• isValidUniverse(b) returns false.
• isValidUniverse(c) returns false.
• isValidUniverse(d) returns true.
1b) Method to display the universe
Write a method displayUniverse() which takes a two-dimensional array of integers as input. In this
method you can assume that the array is a valid representation of a universe (as described above). The
Page 4
method should display the universe using the star character (‘*’) for alive cells, and the whitespace
character (‘ ’) for dead cells. Your method should also display a box (as shown below) surrounding the
actual cells of the universe.
For example, consider the following arrays:
int[][] block = {{0,0,0,0}, {0,1,1,0}, {0,1,1,0}, {0,0,0,0}};
int[][] tub = {{0,0,0,0,0}, {0,0,1,0,0}, {0,1,0,1,0}, {0,0,1,0,0}, {0,0,0,0,0}};
int[][] toad = {{0,0,0,0,0,0}, {0,0,1,1,1,0}, {0,1,1,1,0,0}, {0,0,0,0,0,0}};
Then:
• displayUniverse(block)
prints
• displayUniverse(tub)
prints
• displayUniverse(toad)
prints
1c) Method to get the cell from the next generation
Write a method getNextGenCell that takes as input a two-dimensional array of integers representing
a valid universe, as well as two integers x and y indicating the location of a specific cell. For example,
if x=2 and y=1, the cell analyzed is the one represented by the second element of the third sub-array.
The method returns 1 if such cell will be alive in the next generation of the given universe, 0 otherwise.
Remember that the next generation of cells is determined by the following rules:
• Any live cell with fewer than two live neighbors dies, as if caused by under population.
• Any live cell with two or three live neighbors lives on to the next generation.
• Any live cell with more than three live neighbors dies, as if caused by overpopulation.
• Any dead cell with exactly three live neighbors becomes a live cell, as if caused by reproduction.
For example, consider the following arrays:
int[][] beehive = {{0,0,0,0,0,0}, {0,0,1,1,0,0}, {0,1,0,0,1,0}, {0,0,1,1,0,0},
{0,0,0,0,0,0}};
int[][] toad = {{0,0,0,0,0,0}, {0,0,1,1,1,0}, {0,1,1,1,0,0}, {0,0,0,0,0,0}};
Then:
• getNextGenCell(beehive, 1, 3) returns 1, while getNextGenCell(beehive, 3, 1) returns 0.
• getNextGenCell(toad, 0, 3) returns 1, while getNextGenCell(toad, 2, 3) returns 0.
Note that this method must not modify the input array in any way.
Page 5
1d) Method to create the next generation universe
Write a method getNextGenUniverse that takes as input a two-dimensional array of integers representing a valid universe and returns a two-dimensional array of integers (with equal dimensions) representing
the universe in its next generation. To get full marks, your method must call getNextGenCell().
For example, consider the following arrays:
int[][] tub = {{0,0,0,0,0}, {0,0,1,0,0}, {0,1,0,1,0}, {0,0,1,0,0}, {0,0,0,0,0}};
int[][] toad = {{0,0,0,0,0,0}, {0,0,1,1,1,0}, {0,1,1,1,0,0}, {0,0,0,0,0,0}};
int[][] pentadec = {{0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0},
{0,0,0,0,1,0,0,0,0}, {0,0,0,0,1,0,0,0,0}, {0,0,0,1,0,1,0,0,0}, {0,0,0,0,1,0,0,0,0},
{0,0,0,0,1,0,0,0,0}, {0,0,0,0,1,0,0,0,0}, {0,0,0,0,1,0,0,0,0}, {0,0,0,1,0,1,0,0,0},
{0,0,0,0,1,0,0,0,0}, {0,0,0,0,1,0,0,0,0}, {0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0}};
Then:
• getNextGenUniverse(tub) returns the following array:
{{0,0,0,0,0}, {0,0,1,0,0}, {0,1,0,1,0}, {0,0,1,0,0}, {0,0,0,0,0}}
• getNextGenUniverse(toad) returns the following array:
{{0,0,0,1,0,0}, {0,1,0,0,1,0}, {0,1,0,0,1,0}, {0,0,1,0,0,0}}
• getNextGenUniverse(pentadec) returns the following array:
{{0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0},
{0,0,0,1,1,1,0,0,0}, {0,0,0,1,0,1,0,0,0}, {0,0,0,1,1,1,0,0,0}, {0,0,0,1,1,1,0,0,0},
{0,0,0,1,1,1,0,0,0}, {0,0,0,1,1,1,0,0,0}, {0,0,0,1,0,1,0,0,0}, {0,0,0,1,1,1,0,0,0},
{0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0}}
Note that this method must not modify the input array in any way.
1e) Method to display a given number of generations
Finally, create a method simulateNGenerations. This method takes a two-dimensional array of integers
and one integer n as input. The method should first check if the input array represents a valid universe.
If this is not the case, the method should throw an IllegalArgumentException with an appropriate
message. On the other hand, if the array is a valid representation of a universe, then the method
should display the original seed (i.e. the universe as it has been input) as well as the next n generations
of such universe. Note that, to get full marks, your method must use the methods described above
(isValidUniverse(), displayUniverse(), and getNextGenUniverse()).
For example, consider the following arrays:
int[][] tub = {{0,0,0,0,0}, {0,0,1,0,0}, {0,1,0,1,0}, {0,0,1,0,0}, {0,0,0,0,0}};
int[][] toad = {{0,0,0,0,0,0}, {0,0,1,1,1,0}, {0,1,1,1,0,0}, {0,0,0,0,0,0}};
int[][] pentadec = {{0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0},
{0,0,0,0,1,0,0,0,0}, {0,0,0,0,1,0,0,0,0}, {0,0,0,1,0,1,0,0,0}, {0,0,0,0,1,0,0,0,0},
{0,0,0,0,1,0,0,0,0}, {0,0,0,0,1,0,0,0,0}, {0,0,0,0,1,0,0,0,0}, {0,0,0,1,0,1,0,0,0},
{0,0,0,0,1,0,0,0,0}, {0,0,0,0,1,0,0,0,0}, {0,0,0,0,0,0,0,0,0}, {0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0}};
Page 6
Then:
• simulateNGenerations(tub,2) prints • simulateNGenerations(toad, 3) prints
Page 7
• simulateNGenerations(pentadec, 9) prints (all in one column of course)
Page 8
Question 2: Blackjack (40 points)
For this question, you will write two classes, which you can then use to simulate a game of Blackjack.
We want to represent a standard deck of playing cards which consists of 52 Cards in each of the 4 suits:
Spades, Hearts, Diamonds, and Clubs. Each suit contains 13 cards: Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack,
Queen, King. For this assignment, we will represent the value of a card using an int which has a value
between 1 and 13.
Note that in addition to the required methods below, you are free to add as many other private methods
as you want (no additional public method is allowed).
(a) (8 points) Write a class Card. A Card has the following private attributes:
• A int representing its value
• A String representing its suit
The Card class also contains the following public methods:
• A constructor that takes as input the value and the suit of the card and uses them to initialize
the corresponding attributes. This constructor should throw an IllegalArgumentException if
the inputs do not represent a valid card. A card is considered to be valid if it has a value between
1 and 13 (both included) and if it has one of the following suits: Spades, Hearts, Diamonds,
and Clubs. Note, that your constructor should accept as valid both "Spades", "spades", or
"SPADES" for instance.
• getValue() which takes no inputs and returns the value of the card as a number between 1
and 13.
• getSuit() which takes no inputs and returns the suit of the card as a String.
(b) (32 points) Write a class Deck. A Deck has the following private attributes:
• A array of Card representing the playing cards in the deck.
• An int representing the number of cards left in the deck.
• A static Random numberGenerator.
Initialize the Random numberGenerator “in place” (i.e. on the same line as its declaration) with a
reference to a Random object created with the seed 123.
The Deck class should also have the following public methods:
• A constructor that takes no input. The constructor initializes the two non-static attributes
in order for them to represent a standard deck or cards. Note that this means that the array
of Cards should be initialized with an array of 52 elements containing all 52 possible cards
belonging to a standard deck. You must use at least 1 loop to accomplish this (that is, you
cannot write 52 statements to assign all possible values). Hint: If you create a String array of
size 4 with all the possible suits value in it, you can easily use two nested loops to initialize the
array of cards.
• getNumOfCards() which takes no inputs and returns the number of cards left in the deck.
• getCards() which takes no inputs and returns an array of Cards with all the cards that are
left in the deck. Note that no one should be able to use getCards() and, for instance, made
this deck a trick deck. Hint: review what we have learned about private attributes that are
mutable reference types.
In addition to the above methods, we need to add public methods that allow us to “play” with
the deck. The general idea is to never change the size of the array of cards, but instead use the
attribute representing the number of cards left in the deck to keep track of which cards are still
in the deck after we have played around with it. Note that to write a more efficient code, we will
be thinking of the cards as listed in the reverse order as they appear in the deck from a player’s
Page 9
point of view. This means that the last card in the deck (the one at the bottom of the deck) appears
in the first position of our array, while the card that is on top of the deck will appear in the last
position of the array which represents a card still in the deck (note that this in not necessarily the
last position of the array). For instance, if we look at a fresh deck with 52 cards, then the card at
the bottom of the deck appears in position 0, while the card on top of the deck appears in position
51. On the other hand, if we look at a deck with 26 cards left, then the card at the bottom of the
deck appears in position 0, while the card of the top of the deck appears in position 25.
Here are the additional public methods to be added to class Deck:
• showCards() which takes no inputs and displays all the cards left in the deck (from top to
bottom). For example, if the deck as 4 cards left, you might see displayed something similar to
the following:
6 of clubs, 3 of hearts, 1 of spades, 13 of hearts.
Note that you should not print words such as “king” or “queen”, you can simply display them
as 13 or 12. IMPORTANT: Once again, the first card displayed should be the one on top of
the deck, while the last one is the one at the bottom of the deck. See previous paragraph for a
detailed explanation.
• shuffle() which takes no inputs and shuffles the cards left in the deck. You can do this by
repeatedly generating 2 random indices (from 0 to the number of cards left in the deck) and
swap the content of the array of cards at those two position. Repeat this operation for 1000
times.
• deal() which takes no inputs and returns the Card which appears on top of the deck. If there
are no more cards left in the deck, then the method should return null. Note that
if a card was dealt, then after this operation the deck will contain one less card and the card
returned by the method should not appear anymore as one of the cards left in the deck.
• pickACard() which takes an int as input indicating the position of a card in the deck from the
player’s point of view. If the deck does not have enough cards left, then the method returns
null. Otherwise, the method returns the Card in that position. Please note once again, that
the cards in the array are stored in the reverse order compare to how they appear in the deck
from a player’s point of view. Note that after this operation the deck will contain one less card
and the card returned by the method should not appear anymore as one of the cards left in the
deck.
• restockDeck() which takes no inputs and resets the deck back to its original form. That is,
the deck will then contain all 52 cards belonging to a standard deck.
In order to give you some examples of how your methods should word, I need to start by showing
you what will be displayed if I call showCards() on a “freshly” made deck. This of course will
depend on how the constructor initializes the attributes. On my program, if I create a deck and I
call showCards() on it, the following will be displayed all on one line:
1 of Clubs, 2 of Clubs, 3 of Clubs, 4 of Clubs, 5 of Clubs, 6 of Clubs, 7 of Clubs,
8 of Clubs, 9 of Clubs, 10 of Clubs, 11 of Clubs, 12 of Clubs, 13 of Clubs,
1 of Diamonds, 2 of Diamonds, 3 of Diamonds, 4 of Diamonds, 5 of Diamonds,
6 of Diamonds, 7 of Diamonds, 8 of Diamonds, 9 of Diamonds, 10 of Diamonds,
11 of Diamonds, 12 of Diamonds, 13 of Diamonds, 1 of Hearts, 2 of Hearts,
3 of Hearts, 4 of Hearts, 5 of Hearts, 6 of Hearts, 7 of Hearts, 8 of Hearts,
9 of Hearts, 10 of Hearts, 11 of Hearts, 12 of Hearts, 13 of Hearts, 1 of Spades,
2 of Spades, 3 of Spades, 4 of Spades, 5 of Spades, 6 of Spades, 7 of Spades,
8 of Spades, 9 of Spades, 10 of Spades, 11 of Spades, 12 of Spades, 13 of Spades.
Make sure to initialize the attributes as I did, so that you’ll be able to check that your methods
Page 10
work by matching the examples below.
If I then call shuffle() followed by showCards(), the following will be displayed:
13 of Diamonds, 2 of Clubs, 12 of Diamonds, 12 of Hearts, 6 of Clubs,
1 of Diamonds, 12 of Clubs, 10 of Hearts, 9 of Diamonds, 9 of Spades,
4 of Hearts, 2 of Diamonds, 8 of Hearts, 5 of Diamonds, 11 of Clubs,
8 of Diamonds, 7 of Diamonds, 11 of Hearts, 3 of Hearts, 1 of Spades,
6 of Diamonds, 7 of Clubs, 5 of Spades, 11 of Spades, 10 of Diamonds,
2 of Hearts, 4 of Spades, 3 of Diamonds, 6 of Hearts, 4 of Diamonds,
7 of Hearts, 11 of Diamonds, 6 of Spades, 1 of Clubs, 3 of Clubs, 3 of Spades,
4 of Clubs, 5 of Hearts, 12 of Spades, 10 of Spades, 8 of Spades, 10 of Clubs,
13 of Spades, 5 of Clubs, 1 of Hearts, 9 of Hearts, 9 of Clubs, 7 of Spades,
2 of Spades, 13 of Hearts, 8 of Clubs, 13 of Clubs.
If I then call deal() I receive the card “13 of Diamonds”. If I then call pickACard(11) I receive
the card “8 of Hearts”. If I then call getNumOfCards() I receive 50, and if I call showCards() I see
the following displayed:
2 of Clubs, 12 of Diamonds, 12 of Hearts, 6 of Clubs, 1 of Diamonds, 12 of Clubs,
10 of Hearts, 9 of Diamonds, 9 of Spades, 4 of Hearts, 2 of Diamonds,
5 of Diamonds, 11 of Clubs, 8 of Diamonds, 7 of Diamonds, 11 of Hearts,
3 of Hearts, 1 of Spades, 6 of Diamonds, 7 of Clubs, 5 of Spades, 11 of Spades,
10 of Diamonds, 2 of Hearts, 4 of Spades, 3 of Diamonds, 6 of Hearts,
4 of Diamonds, 7 of Hearts, 11 of Diamonds, 6 of Spades, 1 of Clubs,
3 of Clubs, 3 of Spades, 4 of Clubs, 5 of Hearts, 12 of Spades, 10 of Spades,
8 of Spades, 10 of Clubs, 13 of Spades, 5 of Clubs, 1 of Hearts, 9 of Hearts,
9 of Clubs, 7 of Spades, 2 of Spades, 13 of Hearts, 8 of Clubs, 13 of Clubs.
If I then call shuffle() followed by showCards() I see the following displayed:
12 of Clubs, 5 of Diamonds, 7 of Diamonds, 13 of Spades, 4 of Diamonds,
13 of Hearts, 2 of Hearts, 4 of Spades, 12 of Spades, 10 of Diamonds,
7 of Hearts, 3 of Clubs, 5 of Clubs, 11 of Spades, 5 of Spades, 1 of Diamonds,
11 of Clubs, 9 of Spades, 1 of Hearts, 6 of Diamonds, 11 of Hearts, 4 of Clubs,
4 of Hearts, 9 of Diamonds, 10 of Clubs, 10 of Hearts, 1 of Spades, 8 of Diamonds,
3 of Spades, 13 of Clubs, 7 of Spades, 3 of Hearts, 9 of Hearts, 8 of Spades,
1 of Clubs, 12 of Diamonds, 2 of Spades, 2 of Diamonds, 5 of Hearts, 7 of Clubs,
9 of Clubs, 3 of Diamonds, 6 of Spades, 11 of Diamonds, 12 of Hearts, 6 of Hearts,
10 of Spades, 6 of Clubs, 2 of Clubs, 8 of Clubs.
Finally, if I then call restockDeck() followed by showCards() I see the following displayed:
1 of Clubs, 2 of Clubs, 3 of Clubs, 4 of Clubs, 5 of Clubs, 6 of Clubs, 7 of Clubs,
8 of Clubs, 9 of Clubs, 10 of Clubs, 11 of Clubs, 12 of Clubs, 13 of Clubs,
1 of Diamonds, 2 of Diamonds, 3 of Diamonds, 4 of Diamonds, 5 of Diamonds,
6 of Diamonds, 7 of Diamonds, 8 of Diamonds, 9 of Diamonds, 10 of Diamonds,
11 of Diamonds, 12 of Diamonds, 13 of Diamonds, 1 of Hearts, 2 of Hearts,
3 of Hearts, 4 of Hearts, 5 of Hearts, 6 of Hearts, 7 of Hearts, 8 of Hearts,

(c) (Optional points) Write a class Blackjack. In this class you can set up a main method. You can
use Scanner to interact with a user and simulate a game of Blackjack against the AI. For time
reasons, this part of the assignment as been removed from the required part, but we suggest you
try to implement the game using the two classes defined above. It will help you build a deeper
understanding of how to use objects in Java. Here is a brief outline of how you can go about
simulating Blackjack:
• Create a deck and shuffle it.
• Create an object of type Scanner to interact with the player (i.e. the user of your program).
• Deal two cards, one to the player, one to the dealer (the AI)
• Create a helper method that counts the points obtained in Blackjack from an arrays of Cards
• Show the player their first card and simulate the player’s turn. Until the player wants a card
and did not exceed 21 points do the following
– Ask the player if the want a card
– If so, deal a new card to the player and show it.
• If the player exceeded 21, then they lost.
• If they did not, then simulate the dealer’s turn. Note that the dealer’s turn is very similar to
the players one with the exception that the dealer will keep drawing cards until they either get
a score higher than the player or they exceed 21.
