I have many, many, many more words for those that make games to learn. The rest of my issues with this class is summarised with make hand an arrayList. At the very least it could take the responsibility of passing messages around and handling the game's progression. When you're done playing, you can collect your chips and you just walk away. Collection and it's subclasses. You can make Update be in a while notQuit loop, which can contain all of your logic. These are for documenting your arguments or "parameters" and your return value. The game loop pattern , where you have a initialize then just a update , can apply here, in a simple form. At some point, people leave and the hands end. In a real deck of cards, there are thirteen ranks, four of which are worth ten points in blackjack. I'd just store it in the array. I'd rewrite the function like this:. That's when they're greeted. You can split a pair into two hands. It's true that there are nine possible card values in a game of blackjack, but they're not all equally likely. It's functional, it works, and if you're going for simple, this is it. In this game I have chosen to make it as simple as I can whilst still functional. And some casinos will let you split again if you get more pairs. In goAgain , you're checking the boolean against null. This will make the game a lot less fun. I hope you get more answers and use these in your learning project to post a follow-up question. Then again, card counters might favor just waiting a couple hands to get the better cards So yeah, you'll have to make something ask the user. And the dealer and the player join this table. As a slight aside, I'd make it an ArrayList, but if you're trying to just use simple data types, I understand why not, but it's something to consider if you're planning to allow more than 1 player in the future. Class documentation should tell you what it is. Sadly, you don't have a betting system, so there's no easy way of simply betting 0 and making that a way to leave the table. Blackjack has a split feature. Function documentation should tell you what it does. Right now, you have to do these weird things with copying arrays. It only takes a minute to sign up. Java has gone through quite some versions, and certain common problems have been solved for you already. So this becomes. Whether you want to do that is up to you, but there's plenty of card implementations on this site that'll give you pointers. You don't wanna bother with that, do you? Something nobody else seems to have mentioned yet: your card-selection algorithm gives much lower odds to the player than they'd have in a real game. They get more then 2 cards in blackjack, and the cards can have different values depending on how the hand is Ace can be high or low.

Code Review Stack Exchange is a question scoring blackjack java answer site for peer programmer code reviews. You have Card s. Leave the round of hands out of it. That'd be beyond silly in a casino. I have understood that that is bad and I understand why, so you needn't bother with that.

Your Card class would then have a blackjackValue method that you can use for scoring purposes.

And then they can play hands. I like such exercises. Checking that should be under your whoWon method, and printing it should be controlled by another method. Blackjack comes with a table. I would make the dealer in location 0 of the players array, as this means that you can pass around your array of players, and rely on the fact that no matter how large the array is, player[0] is the dealer. This can include your welcome text. You just have to call List. For now, revising the comment to. There are two players; dealer and user. Questions like these are fun to answer. It's also contradictory to the function name - "game start up" and "start player turn" When I start up a game, I grab a deck, maybe shuffle it and give people cards. PlayerTurn has quite a few responsibilites, which is something that you don't really want out of a function. I didn't touch much on the actual code, although I do hint at things. I am a new programmer I've been doing Java for about 7 weeks and I am of the type who wants to get it right straight away, so I wonder how this code:. This code has a recursive call back to main. User goes first, then the dealer has her turn. I know that you've overridden toString , but that's not the first thing that I'd look for if I were using this interface. This is how I'd write that method:. Well, if I were designing this I'd abuse a physical object. No, not books. I'd definitely make Hand an ArrayList. If there's a stalemate, dealer wins. As well as this, moving all of your initialization logic to a single method might be a good idea. I know that you said that you are aware of the recursive call to main being a bad thing, but I thought I should suggest an alternative anyway. Specifically, I'd like to point you to java. I'd make that the table's responsibility. Variable documentation should tell you what it means. But in the future, I think this method will change to some PlayerAction getAction where PlayerAction is an enumeration of actions a Player could take. To play Blackjack at a casino, you need to place a bet. That'd imply you get 4 of a kind; 77 split to 7 and 7, get two cards, you have 77 77, split again to 7 7 7 7. To other reviewers: I've tackled design and the use of arrays. The game lets the other player auto-win if the hand-total is more than That same function also assures that no player will have a hand higher than The game compares the users results to each other and the highest hand wins. Right now, you've mapped a boolean to hit and stay. This comment doesn't say what the function does. However, I think that this is enough for today. I have to read both the function name and the javadoc to figure out that false maps to hit. As well as this, you're duplicating data by both creating a Player user and a Dealer dealer as well as storing that in the array. Resizing arrays is expensive and adding 1 element to a list is less so. With a List , you can have an ever expanding array without having to copy things around Java will do that for you, internally. What happens if we add split, and double down? Right now, you can get a hand that contains 9 2's. Take a look at a List , Set and Map. The way I would handle this is to actually simulate all thirteen possible ranks with the numbers 2—13 in your random loop. However, it's not very flexible, and it doesn't involve the notion of a deck, so it's possible to get 5 2s in a row. I'd possibly have a getName. Then we can't be sure that false means hit anymore. And any in-code comments should tell you why it does. Your IDE generates things like param and return. You'd call them out on it for sure. Why not a Deck? So perhaps a class like BlackJackTable can be responsible for a lot of things. I'd pass it just one player, the one who's turn that it is, and return without printing out anything other than what it needs to the score after the player has taken a card , as it shouldn't have any responsibility over reporting who won.
