Here in the UK1, these are the income tax rules: You get a personal allowance (untaxed) of up to 12,570: If you earn less than 100,000, you get the full 12,570 as personal allowance For every 2 over 100,000, your personal allowance goes down by 1 After the personal allowance, the next 37,700 is taxed at the "basic rate" of 20% After that, the next 99,730 is taxed at the "higher rate" of 40% Finally, anything above this is taxed at the "additional rate" of 45%.

Using the above tax rules, take in an annual salary (as a positive integer) and calculate the income tax in java.
