Due: 09:59 AM on Friday, Fri, Oct 11 Lab 09 – PicoFermiBagel Points: 100 points
Objective:
This assignment will demonstrate your knowledge of loops, classes, methods, and Java data types.
About:
You will write a Java program to play the game of Pico, Fermi, Bagel.
Rules:
Here are the rules of the game:
1. The computer will generate a “secret” three digit number at random.
2. The first number will not be 0, and all the digits will be different.
3. The user tries to guess the number.
• If the user guesses correctly, then the game is over.
• If not, the computer gives a hint and the player tries again.
Hints:
• For each digit that matches the secret number in the proper place, the computer prints “Fermi”
• For each digit that matches, but not in the proper place, the computer prints “Pico”
• If none of the digits match, the computer prints “Bagels”
Examples (If the program generated the secret number 482):
Hi, I have a number on mind, guess that number?
guess = 637, Bagels
guess = 381, Fermi
guess = 382, Fermi Fermi
guess = 832, Fermi Pico
guess = 328, Pico Pico
guess = 428, Fermi Pico Pico
guess = 482, Winner!
(Game is over)
When the game is over, the results are printed: whether the user won or quit, and the number of guesses made
• To avoid making it too easy for the player, you should print all Fermis first, and then the Picos, for each guess. • To avoid making it too difficult, print all guesses and hints to System.out so the user can scroll through them.
The Bagels Class
Your Bagels class will have only one public method, playGame(). This method will call three other methods to: 1. Generate the secret number
2. Determine whether the current guess is a winner
3. Evaluate the current guess and print hints
Since these methods are called only by a method of the same class – playGame() – and not by the test class, it is customary to declare them private, instead of public. Such methods are sometimes called “utility” methods or “housekeeping” methods since they do “behind the scenes” chores.
OPTIONAL: You may have additional utility methods, also called from playGame(), to get the user’s guess and print the game results.
High-Level Algorithm for the playGame() Method
Generate the Secret Number
do
Get User’s Guess (including option to quit)
If (! userQuits)
Evaluate User’s Guess
while ( not (winningGuess or userQuits) )
Print results – did user win or quit, and number of guesses made
Your Main class
Your main class will create a Bagels object and call the method that plays the game. After each game, give the user the option of playing another.
After the last game, thank the user. That’s all, nothing else.
Additional Specifications
1. The skeleton of the Bagels class you are to use is below. Write the methods bodies and declare instance and local variables as necessary.
2. DO NOT CHANGE THE METHOD DECLARATIONS IN ANY WAY!
3. The user guesses must be entered as a single, 3-digit string. Do not ask the user to enter three separate strings.
Instructions:
• Create a project called Lab09 with a single Java file called PicoFermiBagel.java that contains both classes.
• Be sure to document your code (add comments on top of your java file).
• In the comments add your name, date, course, homework number, and statement of problem.
• Once you are done, upload PicoFermiBagel.java through Blackboard under Lab 09 link.
