Your calcValue function is buggy when it comes to deciding whether to count an ace as a 1 or The Deck object is doing too much. Not only is it a highly Blackjack-specific deck, it also simultaneously serves as model and controller. There should probably be a separate BlackjackDealer object or something.
The giant switch in createDeck should be avoided. It could be replaced with an array or hash lookup. But I don't see why the English name for the card is needed at all. The methods, particularly Card. You don't want each of the 52 cards to have its own showCard function.

First, take a break and play the game to get an idea of how it works. You'll see that various elements on the page are dynamically updated, added and removed during the course of play. Be sure to read the rules provided.
It will help in understanding much of the program flow and comments in the rest of this article. Games necessarily require a good deal of interaction and dynamic content. As it is a fairly large script, some details of the code are omitted. The comments in the source should help explain the finer points and other articles on this site provide good information on many of the techniques used, particularly on using CSS and the DOM. First there are the areas for the dealer and player made up of a main DIV tag containing other DIVs for the cards and text messages.
The style class textBox specifies float: The card area is initially empty but will be filled and cleared dynamically as the game is played. Although the game is designed for a single player, it does allow "splits. Likewise, either of these can be split again if another pair is dealt. To accommodate this, three other sets of DIVs are defined in the code. These are exactly like the main player's area except for the the IDs assigned to each element. The rules limit the player to a maximum of three splits in any round so three additional areas are needed.
As they are usually not used, they have an inline style specifying display: Should the player split a hand, this style setting will be changed programmatically to display the an area and likewise, set to display: Below the playing areas is a form with several buttons.

So when you return the rank of that card, parseInt doesn't know how to handle King.
Java blackjack program Ask Question. NoobCoderChick 8 Sorry I copy and pasted an earlier code. You shouldn't change your original code to the point where the question no longer makes sense. Just add to the bottom so people can see how the problem is evolving without having to read the edit history.
Oh sorry I didn't know you can do that. I thought I had to edit the post. The only thing I see is add comment or answer question, how do I do that? Instead of this line: Following the suggestion by WorldSEnder, you can define a Rank enum: Ted Hopp k 39 WorldSEnder - Yeah, I thought of suggesting that.
