bookChallenge: Names Starting with Letter B

Task

Your task is to write a sortNamesStartWithLetterB method that will return only the names from this array names that starts with the letter B.

  1. Loop through the array and count how many names start with the letter B.
  2. Use the charAt() method to extract the first letter of each name and compare it to the letter B.
  3. Make sure you are checking for the uppercase letter 'B'.
  4. After counting, set the size for the new result array.
  5. Initialize the index variable, which will be used as the index for the result array.
  6. Loop through the array again and add names starting with B to the new array.
  7. Increment the index each time you add an element to the new array.
  8. Return the new array with the names.
  9. In the main method, call the sortNamesStartWithLetterB method.
