12. a. Create a TaxReturn class with fields that hold a taxpayer's Social Security number, last name, firs name, street address, city, state, zip code, annual income, marital status, and tax liability. Include a constructor that requires arguments that provide values for all the fields other than the tax liability. The constructor calculates the tax liability based on annual income and marital status. The following table shows the percentage of income that is taxed. INCOME (S) 0-20,000 20,001-50,000 50,001 and over SINGLE STATUS 15% 22% 30% MARRIED STATUS 14% 20% 28% In the TaxReturn class, also include a display method that displays all the TaxReturn data. Save the file as TaxReturn.java. b. Create an application that prompts a user for the data needed to create a TaxReturn. Continue to prompt the user for data as long as any of the following are true: > The Social Security number is not in the correct format, with digits and dashes in the appropriate positions-for example, 999-99-9999. > The zip code is not five digits. > The marital status does not begin with one of the following: S, S, M, or m. > The annual income is negative. After each item of the input data is correct, create a TaxReturn object and then display its values. Save the file as Prepare Tax.java.

10. Write a program that inserts parentheses, a space, and a dash into a `String` of 10 user-entered numbers to format it as a phone number. For example, 5153485912 becomes (515) 348-5912. If the user does not enter exactly 10 digits, display an error message. Continue to accept user input until the user enters 999. Save the file as `PhoneNumberFormat.java`.

11. Write an application that determines whether a phrase entered by the user is a palindrome. A palindrome is a phrase that reads the same backward and forward without regard to capitalization or punctuation. For example, “Dot saw I was Tod”, “Was it a car or a cat I saw?”, and “Madam, I’m Adam” are palindromes. Save the file as `Palindrome.java`.

12. 
   a. Create a `TaxReturn` class with fields that hold a taxpayer’s Social Security number, last name, first name, street address, city, state, zip code, annual income, marital status, and tax liability. Include a constructor that requires arguments that provide values for all the fields other than the tax liability. The constructor calculates the tax liability based on annual income and marital status. The following table shows the percentage of income that is taxed.
   
   | Income ($)         | Single Status | Married Status |
   |--------------------|---------------|----------------|
   | 0–20,000           | 15%           | 14%            |
   | 20,001–50,000      | 22%           | 20%            |
   | 50,001 and over    | 30%           | 28%            |
   
   In the `TaxReturn` class, also include a display method that displays all the `TaxReturn` data. Save the file as `TaxReturn.java`.

   b. Create an application that prompts a user for the data needed to create a `TaxReturn`. Continue to prompt the user for data as long as any of the following are true:
   
   - The Social Security number is not in the correct format, with digits and dashes in the appropriate positions—for example, 999-99-9999.
   - The zip code is not five digits.
