Question
In this assignment, you will implement a simulation of a popular casino game usually called video poker. The card deck contains 52 cards, 13 of each suit. At the beginning of the game, the deck is shuffled. You need to devise a fair method for shuffling. (It does not have to be efficient.) The player pays a token for each game. Then the top five cards of the deck are presented to the player. The player can reject none, some, or all of the cards. The rejected cards are replaced from the top of the deck. Now the hand is scored. Your program should pronounce it to be one of the following:
You need to implement two classes PokerGame and Card
Card class needs to have the following:
For the PokerGame class, you would need to have the following:
Main method will contain at least the following:
while ( tokens > 0 ) // initial token count is 10
{
System.out.println("You have " + tokens + " tokens."); // display current money!
displayGameMenu(); // prompt user to ask whether they want to play or not
int play = in.nextInt();
if ( play == 1 ) // if player choose to play
{
generateDeck(); // create 52 cards
shuffleDeck(); // shuffle the deck randomly
dealCards(); // deals 5 cards to player's hand
for ( int i = 0; i < 5; i ++ )
{
displayCardMenu( i ); // prompt user to ask them whether they want to keep this card or not
int keepCard = in.nextInt();
if ( keep == 0 ) // 0 means they want to swap the card from their hand to a new card
{
swapCard( i );
}
}
int reward = checkReward(); // check player's hand has awarded anything
tokens += reward;
}
else {
break; // end of the game loop
}
}
