For the second programming project, you will be given most of the Java source code for a working program. The given source code includes all the necessary variable declarations and the mandatory input and output statements. Your task is to complete the given program by adding the Java statements needed to perform the specified calculations. You may modify the given program source code as much as you like. At minimum you must add the calculations. Just be careful if you make other changes since your output must match the formatting of the sample output exactly.

Your program will be submitted to the Curator system. You will have five submissions. You will not be given more submissions for any reason! Your submitted program will be graded by the GTA. There will not be any automatic grading for any project in this course. You will receive your grade via email from the class account cs1054@cs.vt.edu in the form of a grade-sheet. The grade for the project for future assignments include some points for style and design. This program will only be graded for correctness.
You will submit this assignment to the Curator System (read the Student Guide). Instructions for submitting are contained in the Student Guide. You will be allowed up to five submissions for this assignment. Use them wisely. Test your program thoroughly before submitting it. It is advisable to show your program to the instructor or the TA to make sure it works correctly before submitting it. Make sure that your program produces correct results for every sample input file posted on the course website. The Student Guide can be found at: http://www.cs.vt.edu/curator/
The comments used in this assignment are typical of what will be expected for all your projects. Program Compilation Your program must compile and run under JDK 1.5. Pledge Every program submission for this class must include an Honor Code pledge. Specifically, you must always include the following pledge statement in the header comment for your program:
/**************************************************************************** * * On my honor: * * - I have not discussed the Java language code in my program with * anyone other than my instructor or the teaching assistants * assigned to this course. * * - I have not used Java language code obtained from another student, * or any other unauthorized source, either modified or unmodified. * * - If any Java language code or documentation used in my program * was obtained from another source, such as a text book or course * notes, that has been clearly noted with a proper citation in * the comments of my program. * * - I have not designed this program in such a way as to defeat or * interfere with the normal operation of the Curator System. * * Your Name * Your PID ****************************************************************************/Failure to include this pledge in a submission is a violation of the Honor Code.

* Project 2 for CS 1054 Summer 1 2005
* Circle calculations program
*
* File: Program2.java
* Programmer: Mir Farooq Ali
* Java Platform: JDK 1.5.0
* Compiler: Eclipse 3.1.0
* Last modified: June 1, 2005
*
* Purpose: This program computes the coordinates of a bounding box of a circle
* given its center and radius. It also calculates the area and perimeter
* of the circle and the bounding box. The program then writes a summary of its
* findings to an output file called analysis.txt
