Overview

Follow the three-step problem solving process to make a simple dice game. In this assignment it is very important to match output instructions verbatim. First, after a prompt (sentence 1), the user enters an amount of money for a wager. The program then replies with a sentence based on that wager (see options for sentence 2). Then the program simulates rolling two independent six-sided dice by generating two random integers between 1 and 6. The program then reports the rolled values (see format for sentence 3). Finally, the program should use a switch or if/else statement to compute the winnings (or losses) based on the total value rolled and displays a sentence describing the result (see options for sentence 4). The program finishes with a sentence reporting how much money was won (see format for sentence 5).

Output format instructions for sentences referenced above

1. The prompt for the initial wager should say: Enter your wager amount:
2. The program outputs one of the following sentences based on the wager amount:
   • Invalid bet. If the wager is <= 0 (you should reset the wager to zero for them in this case)
   • Small bet. If the wager is >0 and < 15
   • Medium bet. If the wager is >= 15 and < 60
   • High roller. If the wager is >= 60
3. The program outputs this sentence: You rolled X and Y.
   • X and Y should be replaced with the numeric roll values as in the sample runs.
4. The program outputs one of the five following sentences based on the sum of the dice rolls:
   • If the sum is 2 or 12, the player wins 15x the wager. Display: Big winner!
   • If the sum is 3 or 11, the player wins 10x the wager. Display: Medium winner!
   • If the sum is 4 or 10, the player wins 5x the wager. Display: Small winner.
   • If the sum is 5 or 9, the player wins the wager back. Display: Draw.
   • If the sum is 6, 7, or 8, the player loses the wager. Display: You lose.
5. Finally, display this sentence: You won $X
   • X is replaced by the winnings (or zero if the wager is lost)
   • No decimal or formatting is required. Only the dollar sign.

Getting started

Open src/main/java/edu/citadel/DiceGame.java and add your code to the main method. To run your main method locally, enter the run and debug menu on the left, or right-click the main method and select Run Java.

To run the test cases locally, open a terminal and type mvn test. Alternatively, you can open the file src/test/java/edu/citadel/DiceGameTest.java and click the play buttons. You can review the tests in this file, but do not modify any file other than DiceGame.java.

Testing and Submission

When you think you are done, commit your changes to GitHub to trigger the autograder. You can do this on the terminal, or using the Source Control menu option to the left (recommended). You do not need to create a branch or pull request; just commit your changes and push/synchronize them.

If you open the assignment page on GitHub.com you will see the results of your submission. If the tests pass locally when you run mvn test, they should also pass there with a little green checkmark.
