Sports Quiz

Objective

This project will allow you to practice variables, strings, input/output facilities, conditional statements, logical operators, and the Eclipse IDE.

Overview

You will write a very simple application that asks the user to identify how many players are on a baseball, football, basketball, or curling team (or it may ask the user to identify which kind of team has 9, 11, 5, or 4 players.)  It's not the most exciting project, but we have to start somewhere!

This project is considered "open". Please visit the course web page for information regarding the open/closed policy for projects of this course.

Specifications

Your program knows four things:  There are 9 players on a baseball team; there are 11 players on a football team; there are 5 players on a basketball team; and there are 4 players on a curling team.  That's it.

The program begins by prompting the user with:

    Enter 1 to guess a sport, 2 to guess how many players:

The user then enters either "1" or "2".

Processing an Entry of "1"

The program prompts the user with:

    Choose number of players:

The user must enter either "4", "5", "9", or "11".  If any other number is entered, the program will print out "Invalid choice." and will terminate with no further output.

Assuming that the user has entered one of the four valid numbers, the program prompts the user with:

    Which sport has n players?

[In the prompt above, the "n" must actually be either "4", "5", "9", or "11", depending on what the user has selected.]

The user will enter a String.  If the String entered represents the correct sport for the number of players selected, the program will output "Correct!" and terminate.  But if the user has entered the wrong String, then the program will output "Incorrect!" and terminate.

Processing an Entry of "2"

The program prompts the user with:

    Choose a sport:

The user must enter either "baseball", "football", "basketball" or "curling".  If any other String is entered, the program will print out "Invalid choice." and will terminate with no further output.

Assuming that the user has entered one of the four valid sports, the program prompts the user with:

    How many players are on a SPORT team?

[In the prompt above, "SPORT" must actually be either "baseball", "football", "basketball", or "curling", depending on what the user has selected.]

The user will enter a number.  If the value entered represents the correct number of players for the sport selected, the program will output "Correct!" and terminate.  But if the user has entered the wrong value, then the program will output "Incorrect!" and terminate.

Getting Started

In order to help you get started, we have defined a SportsQuiz class with a main( ) method in a file named SportsQuiz.java. This file can be retrieved by checking out the project from the CVS repository. Remember that you must have set up your repository in order to check out and submit projects.  Information on how to do this can be found in the Managing Projects section of the Eclipse tutorial. Follow the instructions given there to check out project Fall06Proj1. This screenshot shows the exact information that you will need to enter while creating your CVS repository connection. After checking out the project, when you switch back to the Java perspective, you will see the above files in the "Package Explorer" window, and you will be able to start modifying them.

If you write the project from scratch, without checking out the "Fall06Proj1" files from your CVS repository, you will not be able to submit your work.

Requirements

• Your program must use the single class SportsQuiz.
• You must use "named constants" for any literal values that will not change during program execution.  (You'll learn about that during the second week of lecture.)
• You must use meaningful variable names and good indentation.
• Input and output operations must be implemented as demonstrated in class.  (I.e. use the Scanner class for input, and use System.out.print or System.out.println for output.)
• You do not need to worry about the user entering the wrong types of values.  If an integer is expected, assume the user enters an integer; if a String is expected, assume the user enters a String.
• You may assume that the user enters either "1" or "2" (and nothing else) after being asked whether they want to choose a sport or the number of players.
• You should not get creative and modify the project specifications. For example, do not add extra behavior or output.
• We use an automated system to grade projects and you will not pass our tests if you do not follow the project specifications precisely. In particular, you must spell things exactly as we have spelled them and use punctuation exactly as we have.  One missing or incorrect punctuation mark (a period, exclamation point, comma, or colon) could cause you to fail all of the tests.  If you spell something wrong ("plaeyrs" or "basketbal" for example) you will fail many of our tests.  PROOFREAD CAREFULLY.  You do NOT need to worry about how many spaces to put between words in your output -- it doesn't matter.  Also, whether or not you capitalize letters doesn't matter in your output.
• Just in case you know what an array is -- you may not use arrays (or any Java collections of any kind) while implementing this project.
• Your program must terminate without using anything like System.exit().  (Don't worry if you don't know what that is.)
• Added 9/12/06: Be sure to only use ONE Scanner for your project. If you use more than one Scanner to read from the input stream, you will fail our tests!

Sample Runs

The following examples show how your program should behave.  Note that items in italics represent the things that are entered by the user.  Keep in mind these are just examples and not the only scenarios that your program is expected to handle.

Example 1: 

    Enter 1 to guess a sport, 2 to guess how many players: 1
    Choose number of players: 5
    Which sport has 5 players? basketball
    Correct!
 

Example 2:

Enter 1 to guess a sport, 2 to guess how many players: 2
Choose a sport: tennis
Invalid choice.
 

Example 3:

Enter 1 to guess a sport, 2 to guess how many players: 2
Choose a sport: baseball
How many players are on a baseball team? 5
Incorrect!

Submission

Submit your project from Eclipse by right-clicking the project folder and selecting "submit".  You may submit as many times as you want -- we we only grade your most recent submission.  After you have submitted your project, you should visit the submit server.  There you can obtain limited feedback about how well your project is performing.  (Choose "release test" to see detailed information.)  The number of times you can run our tests on your project (before the due date) is limited.  The earlier you begin working on the project, the more opportunities you will have to see how your project performs on our tests before the due date!

Grading

There are seven release tests which will be run on your project.  Together, these tests will dictate 90% of the grade on the project.  The remaining 10% will be based on your use of correct programming style.
