i am learning the java. blackjack game is my class work. but i don't how to write the deck class. THANKS



/*
An object of type Deck represents an ordinary deck of 52 playing cards.
The deck can be shuffled, and cards can be dealt from the deck.
*/

public class Deck {

// you should declare the following variables here:
// 1. An array of 52 Cards, representing the deck.
// 2. An int variable cardsUsed indicating how many cards
// have been dealt from the deck.

public Deck() {
// Create an unshuffled deck of cards and initialize cardsUsed

// Hints: try to use a nested for loop -
// one of the for loop counts the suit, another counts the value
// use another counter to count the index of the card creating (0-51)
}

public void shuffle() {
// Put all the used cards back into the deck, and shuffle it into
// a random order. Reset the cardsUsed to zero.

// Hints:
// Method 1: try to use a for loop (e.g. 100 iteration),
// choose 2 random number between 0 and 51
// and swap the two cards in each iteration.
// Method 2: loop for 51 times and swap the current card
// with a random card
}

public int getCardsUsed() {
// As cards are dealt from the deck, the number of cards left
// decreases. This function returns the number of cards that
// are still left in the deck.
}

public Card dealCard() {
// Deals one card from the deck and returns it.
// The card should be the first unused card.
// Hints: use the variable cardsUsed and return the array element
// You need to throw a RuntimeException if no card is left:
// throw new RuntimeException("No card left");
}

public String toString() { // toString method is done for you.
String value = "[ ";
for (int i=0; i<deck.length; i++) {
value += deck[i]+" ";
if(i%13==12 && i!=deck.length-1) value+="\n";
}
return value + "]";
}

} // end class Deck

Welcome to JavaRanch!

You already have some fairly detailed instructions and hints for writing this code. Where exactly are you stuck?
