Goal, Description and Submission Instructions
The goal of this project is to become more familiar with creating and using classes and objects in Java, to further
introduce you to the concepts of abstraction and modularization, and to directly use collections of items.

Instructions
Create a new Java project named “Project1_netid” (where you replace netid with your NetID). Be sure to
include the Text and ListSpinner classes posted on Blackboard, in the Course Materials section. (They
are in the project WheelTemplate). DO NOT MODIFY THESE TWO CLASS FILES IN ANY WAY.

1. Create a Puzzle class in preparation for the next Project, that has the following components:
a. A field for the Puzzle’s category (thing, place, etc.) and a field for the phrase to be guessed
b. Create a constructor that takes a category and phrase as input. *Make sure you convert the values supplied
to the parameters to be all uppercase letters.
c. Write get and set methods for both fields.
d. Write a toString method that prints out the phrase followed by category in parentheses.
e. Create a main method to test the class by creating a Puzzle and printing it out by calling toString().

2. Create a RandomString class (starting from the template on Blackboard) and implement the following:
a. Create a file named wheel_values.txt in the Project1_netid project that contains dollar amounts for the
values in your wheel spinner. Some valid values include 600 or $3,000. This file will have one value per
line. Make sure this file is in the topmost project folder, not inside your src folder (i.e., it should show up
below the JRE System Library).
b. A constructor that receives the name of a file to get string values from. The constructor should read in the
phrases from the file and store them for later use using a private loadStringsFromFile method.
c. next – a method that returns a random string value from the file; this value shouldn’t be repeated until
all guess phrases in the file have been used.
d. shuffle
e. Create a main method to test that next is working correctly by repeatedly calling next & printing the result
– you should not have any repeats, and the phrases should not be in the same order as in the file.
f. Once you’ve verified your RandomString class is working by testing it in main, run the
ListSpinner class to verify your wheel will spin properly.

3. Be sure to:
a. Use proper indentation
b. Use appropriate variable/field names
c. Group like things together (items that are part of the same objects)
d. Use appropriate comments – including comments for each method
e. Check your curly braces

4. For this project you will submit the following (see “Saving and Submitting your Work” for details):
a. A general archive file (e.g. a zip)
b. A runnable JAR file
c. At least one JPG showing your application
