Exercise writes a program for computing taxes using arrays. Design a class named Tax to contain the following instance data fields:

Rewrite Listing, ComputeTax.java, using arrays. For each filing status, there are six tax rates. Each rate is applied to a certain amount of taxable income. For example, from the taxable income of $400,000 for a single filer, $8,350 is taxed at 10%, (33,950 - 8,350) at 15%, (82,250 - 33,950) at 25%, (171,550 - 82,550) at 28%, (372,550 - 82,250) at 33%, and (400,000 - 372,950) at 36%. The six rates are the same for all filing statuses, which can be represented in the following array:

double[] rates = {0.10, 0.15, 0.25, 0.28, 0.33, 0.35};

The brackets for each rate for all the filing statuses can be represented in a twodimensional array as follows:

int[][] brackets = {     {8350, 33950, 82250, 171550, 372950}, // Single filer     {16700, 67900, 137050, 20885, 372950}, // Married jointly                                                                                          // -or qualifying widow(er)     {8350, 33950, 68525, 104425, 186475}, // Married separately     {11950, 45500, 117450, 190200, 372950} // Head of household};

Suppose the taxable income is $400,000 for single filers. The tax can be computed as follows:

tax = brackets[0][0] * rates[0] +

     (brackets[0][1] – brackets[0][0]) * rates[1] +

     (brackets[0][2] – brackets[0][1]) * rates[2] +

     (brackets[0][3] – brackets[0][2]) * rates[3] +

     (brackets[0][4] – brackets[0][3]) * rates[4] +

     (400000 – brackets[0][4]) * rates[5]

Listing

■ int filingStatus: One of the four tax-filing statuses: 0—single filer, 1— married filing jointly or qualifying widow(er), 2—married filing separately, and 3—head of household. Use the public static constants SINGLE_FILER (0), MARRIED_JOINTLY_OR_QUALIFYING_WIDOW(ER) (1), MARRIED_ SEPARATELY (2), HEAD_OF_HOUSEHOLD (3) to represent the statuses.

■ int[][] brackets: Stores the tax brackets for each filing status.

■ double[] rates: Stores the tax rates for each bracket.

■ double taxableIncome: Stores the taxable income.

Provide the getter and setter methods for each data field and the getTax() method that returns the tax. Also provide a no-arg constructor and the constructor Tax(filingStatus, brackets, rates, taxableIncome).

Draw the UML diagram for the class and then implement the class. Write a test program that uses the Tax class to print the 2001 and 2009 tax tables for taxable income from $50,000 to $60,000 with intervals of $1,000 for all four statuses. The tax rates for the year 2009 were given in Table. The tax rates for 2001 are shown in Table.
