In JAVA please. No JAVAFX
In this project you will create a solution designed to play Blackjack. We will use simple
rules of the game. Assume there exists a player and a dealer. The winner of the game is
the player who gets closest to 21 without exceeding 21 or “going bust”. If both players
have the same points, then neither player wins the hand. An ace has a value of 1 or 11.
Face cards have a value of 10. The dealer must take a card if the dealer’s hand is worth
16 or less. The dealer may not take a card if the hand is worth 17 or more. As the player,
you may take a card at any time.
Allow the user to play as many hands as he/she wants.
Keep track of how many hands the dealer wins and how many hands the player wins.
How to get started;
Create a class called Card.
The card has three fields; a value , a suit and a face.
The card class has a constructor that takes three values for the three fields.
Create a no-args constructor.
The Card class has three get methods to return the values of each of the fields.
The Card class has a toString( ) method.
The Card class has a compareTo( ) method that uses the value of the card to determine
the ordering.
Create an equals( ) method that returns true if the parameter Card has the same suit and
the same face as the invoking Card.
Create a class called Deck.
A deck has two fields- an array of Cards and an int which
holds the subscript of the Card at the top of the deck.
The Deck class will have only one constructor, which will create the array. Try to think
of a way to code this without writing 52 statements. (not required)
The Deck class also has a method getTopCard( ) which returns a
copy
of the Card that is
at the top of the array.
The Deck class has a method called shuffle( ) which shuffles the array of Cards. To
shuffle, generate random numbers and use these to exchange array elements. Exchange
1000 times in this method
Create the driver class - call it Game21.
This is where your game logic will go. As a hint, you will need to create two Deck
instances and then call the shuffle method( ) for each. When you are testing as you write,
before you shuffle( ) you may want to print out the entire Deck to make sure you have
created the array of Cards correctly.
Each player is dealt two cards to start. Then the rules stated above are followed. Only the
user has the choice whether to deal another card or quit. The dealer (computer) must be
dealt another card from its deck if its total is 16 or under and must quit if its hand is 17 or
over.
Once a hand is won, either by the computer or the player, allow the player to decide if
he/she wants to play another hand. Keep a running total of the number of hands won by
the computer and the number of hands won by the player. Print these results to a file once
the user decides to quit. Each time the program is run, the results of the session should be
appended to the same output file.
