Problem $1($Decision Structure$)$

Assume that the taxes for citizens are calculated based on the annual income according to the

following hypotheticals:

$$ For incomes of $$20,000$ or less, calculate taxes as: taxes $=$ income $*3\%$

$$ For incomes more than $$20,000$ but less than $$40,000,$ citizens pay $3\%$ on the first

$$20,000$ and $5\%$ on the remaining income

$$ For incomes equal or above to $$40,000$ but less than or equal to $$100,000,$ citizens pay

$5\%$ plus $$500$ fixed amount

$$ For incomes above $$100,000,$ citizens pay $10\%$

$$ The amount of taxes citizens pay per year must not exceed $$20,000,$ regardless of income

Create a program that allows the user to enter the income as input. Once the user enters the

income, your program determines and displays the amount of taxes for that user.

Use any means you wish to get the user$$s input $($terminal or Input Dialog$)$ and display the output

using either terminal or a Message Dialog.

Problem $2($Decision & Looping Structures$)$

Write a program that simulates a simple currency conversion between US dollars and Euros

according to the following sample run. Use this conversion rate, $1$ US Dollar equals to $0\mathrm{.}89$ Euro.

Please notice the simple validation of the user$$s input. The user needs to enter the name of the

currency correctly $($case$-$insensitive$).$ Name your class as Q$2$Currency.java
