Programming Assignment 2 will consist of writing multiple short programs. You will write these programs
from scratch, using the concepts covered so far (variables, operators, selection statements, loops, and
arrays).
Each problem below should be self contained within its own Eclipse project. You will upload these
projects to your GitHub site. Each project must contain the java source code, the project files created by
Eclipse, and the .class files generated when you compile your program. To include the .class files, you
may need to modify your .gitignore file. All three problems should be in the same repository. To keep
things simple, I suggest that you create a new repository on GitHub called <last_name>_PA2 and push
your projects there (instead of the same repo you used for Assignment 1).
You will submit your assignment as both a link to your GitHub page and an upload of your projects as a
*.zip file. Your projects should be named <last_name>_pN, where N is the problem number the
corresponds to each project. You must name your zip file <last_name>_PA2.zip. Failure to adhere to
these naming convention may result in your assignment going ungraded. Due to Webcourse@UCF
limitations, when you submit your assignment, submit the zip file. Add your GitHub URL as a note during
the submission, or as a comment after the submission.
An example structure might be:
hollander_PA2.zip
  |--- hollander_p1
  |--- hollander_p2
  |--- hollander_p3
Grades for this program will be determined according to the rubic. If your project on GitHub does not
contain the complete Eclipse project structure (i.e. the .project file, .classpath file, your .java files, and
your .class files), it will not be graded. This requirement is in place so that my graders can either pull
your code directly from git or unzip it and run it without modification. Similarly, if your project does not run
when we try and open it, it will not be graded. This is most likely to occur if you put all of your files in the
same directory. By default, Eclipse separates the source and binary files; so your GitHub repo should
reflect this structure (it's defined in your .classpath file).

Problem 1
A company that wants to send data over the Internet has asked you to write a program that will encrypt it
so that it may be transmitted more securely. All the data is transmitted as four-digit integers. Your
application should read a four-digit integer entered by the user and encrypt it as follows: Replace each
digit with the result of adding 7 to the digit and getting the remainder after dividing the new value by 10.
Then swap the first digit with the third, and swap the second digit with the fourth. Then print the
encrypted integer. Write a separate application that inputs an encrypted four-digit integer and decrypts it
(by reversing the encryption scheme) to form the original number.
Problem 2
The formulas for calculating BMI are
or
Create a BMI calculator that reads the user’s weight and height (providing an option for the user to select
which formula to use), and then calculates and displays the user’s body mass index. Also, display the
BMI categories and their values from the National Heart Lung and Blood
Institute: http://www.nhlbi.nih.gov/health/educational/lose_wt/BMI/bmicalc.htm
(http://www.nhlbi.nih.gov/health/educational/lose_wt/BMI/bmicalc.htm) so the user can evaluate his/her BMI.
Problem 3
Write a simple polling program that allows users to rate five topics from 1 (least important) to 10 (most
important). Pick five topics that are important to you (e.g., political issues, global environmental issues,
food, video games). Use a one-dimensional array topics (of type String ) to store the five issues. To
summarize the survey responses, use a 5-row, 10-column two-dimensional array responses (of
type int ), each row corresponding to an element in the topics array. When the program runs, it should
ask the user to rate each issue. Multiple people should be able to respond to the survey during a single

run of the program. Once all responses have been logged, have the program display a summary of the
results, including:
1. A tabular report with the five topics down the left side and the 10 ratings across the top, listing in
each column the number of ratings received for each topic.
2. To the right of each row, show the average of the ratings for that issue.
3. Which issue received the highest point total? Display both the issue and the point total.
4. Which issue received the lowest point total? Display both the issue and the point total.
