The program below uses a class, TaxTableTools, which has a tax table built in$.$ The main method prompts for a salary, then uses a TaxTableTools method to get the tax rate. The program then calculates the tax to pay and displays the results to the user. Run the program with annual salaries of $10000,50000,50001,100001$ and $-1($to end the program$)$ and note the output tax rate and tax to pay.

Modify the TaxTableTools class to use a setter method that accepts a new salary and tax rate table.

Modify the program to call the new method, and run the program again, noting the same output.
