Question is in attatchment. Thanks! 1. Create a class named TaxCalculator with the following:a. A double data type variable named "annuallncome".b. A double data type array containing the following values in this order:0, .1, .15, .23, .28, .33, .35C. A method which takes annual income as a parameter and prints the tax calculated asper the below tax bracket:i.Tax brackets:Tax Bracket 0: Income <= 0Tax Bracket 1:0< income <= 9999Tax Bracket 2: 9999 < income <= 39999Tax Bracket 3: 39999 < income <= 89999Tax Bracket 4: 89999 < income <= 189999Tax Bracket 5: 189999 < income <= 399999Tax Bracket 6: 399999 < incomeConditionally check 1 of the 8 different income brackets given above to findwhere the user's income falls.ii.Assume the array elements (from 1.b above) match with these incomebrackets sequentially (i.e, if your bracket is 0 < income <= 9999 then the taxrate is .1, which is the 2nd element in your array), calculate and print theamount of tax they will pay- where a users' tax will is calculated as annual income * tax rateii.iv.For example, if annual income is $200,000, which falls in tax bracket 5, thentax rate would be .33 & therefore the tax paid would be $66,000... Ouch!2. Create another class TaxCalculatorDemo. In that:a. Make an object of TaxCalculator class.b. Take annual income as input from the user and set to object's annuallncome andprint the total tax to be paid.c. Use try...catch block while taking the user's annual income and if the user enters a"non-double" input (like string), then print "Invalid income entered".d. Show output for valid and invalid user entry.

The given problem is related to programming where the class and a demo to drive the class and create…

4) Question 2 asked you to compute the number of possible passwords with various numbers of characters. However, it seems more likely that most people will choose actual words for their password. According to the website wordfinder.yourdictionary.com, the English language has approximately 23,000 six-letter words. a) Assume that a password must be at least 8 characters long and include at least 1 digit and at least 1 special character (again, assume there are 30 of these that are allowed). If people form their password by taking an English word of exactly 6 letters (assume that this password is not case-sensitive) and then adding (in either order) a digit and a special character (e.g flames#1), how many passwords would be possible? (Hint: Find the number of passwords with 6 letters followed by a digit and a special character, then exchange the order of the last two characters.) b) How does your answer change if we assume passwords are case-sensitive and the password must…
