Simple blackjack java program code

Jan 14,  · I am very new to Java and programming theory and desperately trying to improve my knowledge. This is the first program I've made without help and really would appreciate some feedback. I know there must be 1,, better ways to do what I did. You repeat the code .

Java simple BlackJack, UKRAINA-KREDIT.INFOinterException. Ask Question Asked I'm doing an assignment where I have to write/fill in some code to write a simple blackjack program. There are three classes I have defined, a Card Class, a Hand Class (which is an array of Cards and some other values) and a Deck class which is also an array of Cards.

The Overflow 9: Rust and Redux. Waiting for the end of the game. It's the rules of the game that define what value a hand has, and that's why handValue is a method of the Blackjack class. This is Note that Deck , Suit , Value , and Card are all more general concepts that exist outside of blackjack.

There are three classes I have defined, a Card Class, a Hand Class which is an array of Cards and some other values and a Deck class which is also an array of Cards.

In the Hand class I have a method that adds up all the values of the cards, and whenever I run my code, I get a java. NullPointerException, and the console points to my this "addHand" method:. I think it is because some of the values in Cards[] are null. But the "counter" should not let any of them get added. I'll include the rest of the Hand Class, as well as the Card Class. You may also want to add a check to your addCard Card method so that null cards cannot be added.

It depends on call to addCard method. This method is setting card to your cards variable. Suppose you called addCard 3 times, then 0, 1 and 2 iteration of the loop in addHand will be ok but iteration 3 will through exception because cards[3] is null. Learn more.

Continuing my previous post , I have completed my game of Blackjack, the simple version. I am aware it's very long. I haven't included some of the suggested changes suggested in the previously to the Deck implementation and the other classes involved. I am almost tempted to make a superclass since they share too many class attributes and methods.

But I think the idea of "dealer" and "player" are very different concepts even though in this situation they share many features. Furthermore, I have no clue how I would name the superclass. I would love suggestions on how to make this game better and also approaches about the missing features. You don't mention why you didn't follow the advice from your previous post about using enum values rather than custom classes. Note that you can customize an enum. Overall, I think you make too much use of interior classes.

There are times to do that, but this doesn't seem to be one of them. Note that Deck , Suit , Value , and Card are all more general concepts that exist outside of blackjack. Hand also exists in other games, but the rules are different. Perhaps Hand should stay in Blackjack. It would be more common to put each class in separate files in a common package named something like tld.

You never use player2 or player3. You don't actually need any of them. You could just say. I'm guessing that you intend this as the number of cards in a deck. But of course, you never use this constant, so you can get rid of it. You have a magic number 13 here. You should get rid of it. The obvious solution would be a constant, but we can do better with enums for suits and ranks.

This is not only more idiomatic but shorter. If you really wanted, you could do this with arrays instead. But enums fit this situation exactly. The state and bet variables should be a characteristic of a Hand , not a Player. Either there should be a collection of hands per player, or Hand should not be part of Player at all.

We can walk you through how to count cards in blackjack in just a few easy steps… Most people think card counting has to do with memorization. So card counting is simply using a system to keep track of the ratio of low cards to high cards. With Hi-Lo, the most common card counting system, the card values are as follows:.

A card counter does this for each card that comes out of the shoe: card after card and round after round until the dealer shuffles the cards again. Back in the days of single deck blackjack, this information would have been enough to start betting accordingly. If the running count increases, the advantage begins shifting to the player. In an attempt to thwart card counters, casinos began using multiple decks. Nice try, Casinos! When using perfect basic strategy and card counting, we are able to use this information to bet according to our advantage.

The true count will also inform us of when to change our playing strategy. We provide free charts of playing deviations to our members. The true count will tell us what our advantage is at any point in a multiple deck blackjack game. To calculate our True Count, we simply divide our Running Count by the number of decks left to be dealt. So a true 1 would basically erase the house edge and blackjack would be an even game. This can vary greatly depending on the rules and how many cards get dealt before the shuffle.

In order to capitalize on the information you get from counting, you have to raise your bets as the true count rises. This article gives a good overview of the things involved: Recommended Blackjack Bankroll. When a remaining shoe has a higher concentration of tens and aces, statistically there will be more blackjacks dealt.

Because of those mathematical realities, a card counter can keep careful track of the concentration of the shoe, placing bigger bets when more high cards exist and smaller bets when more low cards exist. We owe everything to the card counters who came before us, beginning with Ed Thorp. Thorp was a mathematician who figured out that by removing a single 2 from a deck of cards made blackjack a positive expectation for the perfect basic strategy player.
