***10.8 (Financial: the Tax class) Programming Exercise 8.12 writes a program for computing taxes using arrays. Design a class named Tax to contain the follow- ing instance data fields:

■     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 construc- tor 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 3.2. The tax rates for 2001 are shown in Table 10.1.
