CS 1054: Project 6: Using Inheritance (Summer 2005)

You will use the concept of inheritance for this project.

Problem description (Programming problem 8.2 from textbook)

Complete the classes that were assigned in Lab 10. You will utilize the Student and Person classes from the lab exercise.

You will read in some data from an input file and then create student objects based on that data. The data contained in these objects should then be printed out using the toString method of the Student class. The toString method should be modified to allow printing each student as indicated below. Sample input and output is shown below.

Requirement: You are required to have three classes in this project with the following names: Student, Person and Test. The Test class should contain the code for reading the data in from the input file and creating one Student object per input line. It is also where the processed data should be printed out.

Sample input and output

The input file should be called input.txt and can contain any number of lines similar to shown below. Each line has various fields separated by the ':' character. The fields are name, address, phone number, email address and status. 
Buggs Bunny: 123 Disney World, Orlando, FL 32801: (321)123-4567: buggsbunny@disney.com: Freshman:
Donald Duck: 124 Disney World, Orlando, FL 32801: (321)123-4568: donaldduck@disney.com: Freshman:
Mickey Mouse: 125 Disney World, Orlando, FL 32801: (321)123-4569: mickeymouse@disney.com: Senior:
Roadrunner: 126 Disney World, Orlando, FL 32801: (321)123-4570: roadrunner@disney.com: Junior:
Minnie Mouse: 127 Disney World, Orlando, FL 32801: (321)123-4571: minniemouse@disney.com: Sophomore:
All output should be written to a file called output.txt. A sample output file is shown below:

Hints and suggestions

  1. Use the useDelimiter method of the Scanner class to specify the ':' delimiter in the input fields.
  2. You might have to use the trim() method of the String class to get rid of a preceding newline character.
  3. You should use the super operator in the Student class to obtain the name, address, phone number and email fields from the Person class. Since the above-mentioned fields should be declared as instance variables, you would need get/set methods to access/modify them in the Person class.
  4. Refer to your lab exercises, previous programs, and class notes if you need more help. Also remember that the instructor and GTA are there to help you. Do not hesitate to contact them for any sort of help that you need.

Evaluation

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 be no 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. This project will be evaluated for style and design as well as correctness. Make sure you follow the standard Java conventions for indentation, variable names and documentation in your program. Look at programs 1 and 2 for examples of acceptable documentation. 60 of the 80 points will be correctness, while 20 points will be for style and documentation.

Submitting your Program

For this project, create a folder called P6. Put all the three required files Student.java, Person.java and Test.java in that folder. Zip or compress that folder. You can do this in Windows by right-clicking on the folder, then selecting "Send to" and finally, "Compressed (zipped) folder". You will submit this P6.zip file that gets created to the curator. As indicated earlier, 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. The Student Guide can be found at: http://www.cs.vt.edu/curator/

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.

Failure to include this pledge in a submission is a violation of the Honor Code.
