Class Project – Dice Game
Objectives
The goal of this project is to help the student bring together all of the concepts learned
throughout this course. The following are the main concepts for the project:
• Use of local and global variables
• Understanding data types and data type conversions
• Use of arithmetic expressions
• Use of if/else/switch statements
• Use of for loops, while loops
• Use of arrays
• Use of Scanner for user inputs
• File I/O
• State driven logic
• Use of methods
Hand-in Requirements
All projects will be submitted electronically only via Canvas. Students will compress their
project directory and submit as a zip file. The zip file must contain at least the following file:
• DiceGameAbc123.java
Where “Abc123” should be replaced by your actual abc123. If your project requires any
other files for loading saved state resources, you must include those as well.
Game Logic
The program will emulate a modified version of the dice game like “craps”. Craps use two
six-sided dice containing numbers 1 through 6. Craps is played according to the following
rules:
1. The Come-out Roll aka “the first roll” of the two six-sided dice:
• If the sum of the numbers on the dice is either 7 or 11; the player wins and
the game is over.
• If the sum of the numbers on the dice is either 2, 3 or 12; the player loses,
and the game is over. (aka crap out)
• If the sum of the numbers on the dice is any other number, that number
becomes the point, and the game continues
2. Follow-up rolls, aka “rolling the point”:
• If the initial roll results in a point, the player will continue to roll the dice and
win every time they roll the same point.
• If the player rolls any other number that is not “the point” or “7”, the game
continues to the next roll
• If the player rolls a “7”, the game is over. (aka 7 out)
3. Betting: to keep things simple, betting and winning will be modified from traditional
rules
• Before the initial roll, the player must place a bet up to their current bank roll.
The program must check to see if they still have money in their bank roll.
• Once a bet has been placed, the player can win an equal amount (1:1) based
on the rules set up in steps 1 and 2.
• A player will lose only the amount they bet, not their cumulative winnings,
based on the rules in steps 1 and 2.
Tasks
1. Create method(s) game menus with the following information:
a. An intro message: i.e. “Welcome to Juan’s Dice Game: Main Menu” (replace
Juan with your name)
b. Main Menu Options
i. “Log In”
1. Allow the user to enter a username. No password required
ii. “Register”
1. Allow the user to create a new account
iii. “Quit”
1. Ends the game and quits the program
c. Game Menu Options; update the intro message to reflect this menu location
i. “View Bank Roll”
ii. “Place the bet”
iii. “Roll the dice”
iv. “Back to Main Menu”
2. Create a method(s) to handle the game logic based on the rules defined in the
‘Game Logic’ section of this document.
3. Create a method(s) to handle the registration
4. Create a method(s) to handle the log in
Details
Register Logic:
The user will be allowed to register using an email address, first and last name. This
information will be stored in a file, along with an initial bank roll of $500. Your program must
check to make sure that each user’s email address is only used once, duplicates are not
allowed. First and last names must also only contain alphabet letters. Appropriate error
messages must be displayed for any input errors encountered. Once the user is registered,
the main game options must be displayed.
Log in Logic:
The user will be allowed to log in by entering an email address. The program must look for
this data stored in a file; if the data is found, the main game options are displayed. Your
program must load the remaining bank roll from file. If the data is not found, an appropriate
error message must be displayed instructing the user to register before proceeding. If the
user’s bank roll is $0, an error message must be displayed letting the user know they can no
longer play. If the data is found and the bank roll is greater than $0, proceed to the main
game menu.
View Bank Roll Logic:
The user will be allowed to view their current bank roll only in between current playing
sessions, that is prior to the initial roll or after they win or crap out/7 out. The bank roll must
reflect current wins/losses based on game play. This data should be stored in a file to
prevent data loss.
Place bet logic:
The user will be allowed to enter any positive whole integer, up to their current bank roll.
This is the number that will be used to calculate winnings and losses. The program must
check to make sure this number is not greater than their bank roll; present an error
message otherwise. The program must also check for valid integer values, present error
message otherwise.
Roll the dice logic:
Based on the game logic section of this document, the program must calculate the
winnings based on the amount of each bet.
The Come-Roll example:
If the bet is $50 and the player rolls a 7 on the first roll, a message will be displayed
letting the user know they rolled a 7 (with each individual number rolled: i.e.: 6-1, 4-
3, 2-5) on the come-out roll and the player has won an amount equal to their bet,
which is immediately added to their bank roll. Their bet is also added back to their
bank roll and the player is presented with the game menu options.
The Craps-out roll example:
If the bet is $50 and the player craps out on the initial roll, a message is displayed to
the user letting them know what was rolled (each individual dice) and that they crap
out and lost, then the $50 is immediately deducted from their bank roll and the
player is presented with the game menu option.
Follow-up (“point”) Roll example:
If the bet is $50 and the player rolls an 8, this number becomes the point; a message
must be displayed to the player displaying the number they rolled (each individual
dice) to let them know this is the point. The player will be prompted to roll again,
each roll will be displayed to the player. If this new number matches the point, a
message must be displayed to the player that they rolled the point number and have
won an amount equal to their bet, this amount is immediately added to their bank
roll. The player must roll again. This process continues until the player rolls a 7 (7-
out), at which point a message is displayed to the player with the dice roll and that
they 7-out and lose their initial bet. This initial bet is immediately deducted from
their bank roll and the player is presented with the game menu option.
Back to main menu logic:
This menu option will be treated as the end to the gaming session, meaning that the user is
done playing and will be logged out. The program must save all appropriate data to file to
be used if the user decides to log in later. This menu option does not end the program, only
the game session.
Quit Logic:
Stop the program.
