Java Programming Question 12I am having trouble figuring this out. Help if any input and output would be helpful. **Educational Website Content:**---**Chapter 7: Characters, Strings, and the StringBuilder****Exercise 10: Phone Number Formatter**- **Objective:** Write a program that processes a user's input, ensuring it is a 10-digit number, and formats it into a standard phone number format with parentheses, a space, and a dash.- **Example:** Convert `5153458912` to `(515) 345-8912`. - **Error Handling:** If the user input is not exactly 10 digits, display an error message and prompt again until a valid number or the exit code `999` is entered.- **File to Save:** `PhoneNumberFormat.java`**Exercise 11: Palindrome Checker**- **Objective:** Create an application that checks if a user's input is a palindrome. A palindrome reads the same backward as forward, ignoring capitalization and punctuation.- **Examples:** "Dot saw I was Tod", "Was it a car or a cat I saw?", and "Madam, I’m Adam".- **File to Save:** `Palindrome.java`**Exercise 12: Tax Return Application**- **Part A:** Design a `TaxReturn` class to manage taxpayer information, including fields for Social Security number, last name, first name, address, city, state, zip code, annual income, marital status, and tax liability. - **Calculation:** The constructor calculates tax liability based on specified income brackets and marital status. **Income ($) | Single Status (%) | Married Status (%)** 0–20,000 | 15 | 14 20,001–50,000 | 22 | 20 50,001 and over | 30 | 28- **Part B:** Create an application to collect user data to instantiate a `TaxReturn` object. Continue prompting the user until: - Social Security number is correctly formatted (e.g., `999-99-9999`). - Zip code is exactly five digits. - Marital status starts with: `S, s, M,` or `m`. - Annual income is non-negative.- **Data Validation:** After each valid input, instantiate a `TaxReturn` object and display its values.- **Files to Save:** `TaxReturn.java`, `PrepareTax.java`---**Visual Explanation:**A table is included in the tax section to illustrate the
