Property Taxes

Due Monday, September 23 by 11:00pm

Introduction

Purpose: This program is designed to calculate real estate taxes for the city of Harrisonburg.

Objectives - At the conclusion of this exercise the student will demonstrate that they can:

Input data from a keyboard.
Do everything necessary to create, debug, and run a java program.
Use comments to delineate each section of the program.
Adhere to a Style Guide.
READ AND FOLLOW DIRECTIONS!!!!!

Deadlines

Submit: September 21, 2009 by 11:00pm.
Report: September 22, 2009 at the beginning of class. A late penalty will apply for each of the 2 deadlines. If the submit is late, the report is due the next class or lab session day after successful submission. Programs will not be accepted after 7 days late.

Prerequisites

You have covered the material in Chapter 2 of Gaddis.

Background

Property taxes in Harrisonburg are based on the value of the real estate that a person owns. Property taxes pay for many of the services provided to those owners, such as schools, parks, etc. The value is assessed for each property and owners pay a fee based on the assessed value of the property and the current tax rate. For Harrisonburg city, that tax is rate is $.59 for every $100.00 of value. The $100 of value is rounded, so that if a property was assessed at $159,949, the property tax would be paid on $159,900, but if a property was assessed at $159,999, then that property tax would be paid on $160,000.

Example

If you are a homeowner with an assessed value on your home of $150,000, you would pay $885.00 in taxes. ($1500 * $.59). A second example, if your home was assessed at $142,650, you would pay $841.93 ($1427 * .59).

Program Behavior

Your application must be named HarrisonburgTax.

Your application must do these things:

Your program will prompt for and read two input values. They are:

The name of the property owner as a String.
The assessed value of the property as a double.

Your application must calculate the amount of taxes for that property.
Your application must output the tax amount in the correct format as specified below.

HINT: The Math class provides a number of functions one of which will be helpful to this problem. We will discuss how to use those in class on Monday. The book has an appendix that contains all of these methods. If you don't know how to use this class, you can simply code the problem without the rounding and then fill in the rest after Monday's class.

Output

Output the heading, "Welcome to the Harrisonburg Property Tax Calculator" followed by the newline character.
Output a blank line.
Prompt for the input values. Output the newline character after reading the each input value and before the next prompt. Note: your input will be on the same line as the prompt.

Your first input prompt must be the String, "Enter the assessed value of the property: "
Your second input prompt must be the String, "Enter the property owner's name: "

After reading all of the input values, output a blank line then the name of the property owner. On the next line print out a tab character, then "Taxes on XXXX are YYYY." Substitute the assessed value for XXXX and the tax amount for YYYY. Format the amounts in normal currency format.

Welcome to the Harrisonburg Property Tax Calculator

Enter the assessed value of the property: 
Enter the property owner's name: 

Nancy Harris
    Taxes on $150,000.00 are $885.00.

Error handling

You will not need to perform any error handling. Assume that the values being entered are a String and an double respectively.

Additional Program Requirements

You must use variables for the values of the input parameters.
You must use a constant for the property tax rate.
In the documentation for the main method, you must supply three different examples of the calculation, showing the assessed value and expected tax. This is worth 10 points.
Your program must conform to standard Java programming standards and the additional standards for this class. See the Style Guide for your class.

Honor Code

This work must conform to the JMU Honor Code and the specific requirements of this class. NO help may be provided by any student to another student. Authorized help is limited to your textbook, the TAs for any CS139 or CS239 section, and the professor for your section. See collaboration policy.

Grading

Your program will be evaluated both by its correctness and conformance to the required elements.
You will achieve a grade of 70 for a program that runs correctly and produces exactly the required output in the required format.
Documented examples - 10 points.
The remainder (20 points) will be based on your conformance to the Style and other requirements of the assignment. Review the Style Guide before submitting your program and the grade sheet which is produced by the submit system.
All grades will be based on 100 points.
You may submit any number of times. The only one I will count is the one that corresponds to the hardcopy report that you turn in.
The hardcopy that you turn in will be the formatted version that I will check. Make sure it has no line wraps or other spacing issues.
Successfully submitted programs that are late will be graded, then the late penalty is assessed for each day late according to the following schedule.

For submissions after:

Sept 21 - 5 points
Sept 22 - 15 points
Sept 23 - 25 points
Sept 24 - 35 points
Sept 27 - 45 points
Sept 28 - 100 points

HINTS

Begin early. Students run into trouble by waiting too long to start the program.
Understand the problem at hand. Make sure that you follow the requirements precisely. Don't add additional "flourishes". You will be downgraded.
In the body of your main method, outline your steps with comment lines for each part of the project.
