Description:
The following workshop lets you practice basic java coding techniques, creating classes, methods, using arrays.
Task 1:
The Canadian federal personal income tax is calculated based on filing status and taxable income. There
are four filing statuses:
• single filers
• married filing jointly or qualified widow(er)
• married filing separately
• head of household.
The tax rates vary every year.
If you are, for example say, single with a taxable income of $10,000, the first $8,350 is taxed at 10% and
the other $1,650 is taxed at 15%, so, your total tax is $1,082.50.
Design a class named IncomeTax to contain the following instance data fields (Chose the data fields types
on your own):
1. filingStatus: One of the four tax-filing statuses:
• 0—single filer
• 1— married filing jointly or qualifying widow(er)
• 2—married filing separately
• 3—head of household.
2. Use the constants
• SINGLE_FILER(0)
• MARRIED_JOINTLY_OR_QUALIFYING_WIDOW(ER) (1)
• MARRIED_SEPARATELY (2)
• HEAD_OF_HOUSEHOLD (3)
to represent the statuses.
3. A double-dimension array (You decide the type of it) named intervals: Stores the tax intervals/ brackets
for each filing status.
4. A single-dimension array (You decide the type) named rates: Stores the tax rates for each interval.
5. A variable taxableIncome: Stores the taxable income.
6. Provide the getter and setter methods for each data field and the getIncomeTax() method that returns
the tax.
7. Provide a no-arg constructor.

8. Provide the overloaded constructor IncomeTax(filingStatus, intervals, rates, taxableIncome).
Write a program that prompt the user with a simple menu system of three choices:
• Compute personal income Tax
• Print the tax tables for taxable incomes (with range)
• Exit
❖ With choice one your program should prompt the user to enter the filing status and taxable income
and compute the tax.
❖ With choice two your program should use the IncomeTax class to print the 2001 and 2009 tax
tables for taxable income from (ask the user to input the amount) to (ask the user to input the
amount) with intervals of $1,000 for all four statuses.
The tax rates for the year 2001 and 2009 are given in Tables below.

35% $372,951 + $372,951 + $186,476 + $372,951 +
For each filing status there are six tax rates. Each rate is applied to a certain amount of taxable income. For
example, of a taxable income of $400,000 for single filers, $8,350 is taxed at 10%, (33,950 – 8,350) at 15%,
(82,250 – 33,950) at 25%, (171,550 – 82,250) at 28%, (372,950 – 171,550) at 33%, and (400,000 – 372,950)
at 35%.
