JAVA Craps game code?
Join Stack Overflow to learn, share knowledge, and build your career. I am new to Java and was trying to learn by doing some excercises that I found online. So please excuse me if this is too naive. In the game of craps, a pass line bet proceeds as follows: If the point is rolled first, then the player wins the bet. If a 7 is rolled first, then the player loses. Write a program that simulates a game of craps using these rules without human input.
Instead of asking for a wager, the program should calculate whether the player would win or lose. The program should simulate rolling the two dice and calculate the sum. Add a loop so that the program plays 10, games.
Add c ounters that count how many times the player wins, and how many times the player loses. At the end of the 10, games, compute the probability of winning [i. Over the long run, who is going to win the most games, you or the house? Everytime I run the code the do-while condition gets executed first, so please can anyone help me figure out where I am going wrong? Do while is doing exactly what it you should expect it to do. Executes the body first then evaluates the conditional to see if it should run again.
You don't actually need a do while though, you want to run until one of the conditions breaks you out of the while loop. Another thing that might help is not declaring all the variables at the top of your method. You don't need scorenew or point outside of the third condition, in fact you don't need scorenew at all since you have point:. This condition is always true, so you have an infinite loop.

Below is a long messy one method code for a craps game. The user can play the game multiple times and has the option to quit when ever they want. All repeated chunks MUST be extracted to methods. The ideal is Extract till you Drop. I think it's easiest if I start by stepping through your code, line by line and then see what happens when I get to the stuff that's bugging me:. I value indentation as one of the easiest tools to improve readability of code You should really indent the code inside your main-method Additionally I personally prefer System.
A Scanner is not a Keyboard! Don't number your variables! Do not number your variables. Don't do that it's confusing and trips people up. Declare variables as close as possible to their usage. Oh right, this is number one? What is the difference between keyboard and keyboard4? Don't declare stuff you already declared again! Instead reuse your already declared keyboard And here's where the real fun starts. Remember what we did earlier.. This is our first candidate to extract into a method.
What are we doing? We are prompting user input and expect a double out of it. We need a string to ask the user for something. Well then our method head and also body is clear:. We can further optimize this. How about taking that new Scanner System. This makes the first line unneeded Either we get in a validation for the input right there or we skip the assignment:.
It's not really much shorter, but I think you now can read over it and understand it faster now. The point is, you can drastically change your code by extracting repetitve blocks of logic into methods and elements common to these logic steps into class-level fields. I hope to see a version of your code where you applied a few of the tricks I gave to you here throughout the whole code ;. I have used enum for game results representation GameResult , here should be cases for all game results, so for example WIN case are related to 7 and 11 according to given logic.
It's easy to find the craps tables on any casino floor - just follow the shouts! Perhaps no other game in the casino offers the sort of communal thrills and spills as craps.
Like all forms of gambling, it's impossible to gain an edge over the "house" while playing craps. However, it is possible to maximize your thrills and minimize your spills with smart betting strategies.
See Step 1 below to get started. Note that this guide assumes the reader knows how to play craps. For basic information regarding rules, etc. Always prioritize the safest bets on the table. If you have a massive bankroll and can stand to lose lots of money for the thrill of a few big wins, you can probably make high-risk, high-reward bets to your heart's content. Otherwise, it's smart to take only the safest bets - the ones that offer the smallest house edge.
By doing so, you minimize your risk - while the house will still have a mathematical advantage, it will be as low as possible. Take relatively safe pass bets. Though there are many, many betting possibilities in the game of craps, the safest bets are, luckily, fairly simple. The simplest, most fundamental bet in the game of craps, the pass bet, is also one of the very safest, with a low house edge of 1. If another number is rolled, this number becomes the "point" and the shooter continues rolling.
If a 7 is rolled before the point is rolled again, you lose, while if the point is rolled again before a 7, you win. Don't make pass bets after the come out roll - this is allowed, but the value of the bet diminishes. For the absolute lowest house edge, take don't pass bets. The don't pass bet is almost the opposite of the pass bet - 2 or 3 on the come out roll win, 7 or 11 lose 12 pushes.
