Which class is used to write data to a file in the BasicFileOutput example?

  1. FileWriter

  2. BufferedWriter

  3. PrintWriter

  4. FileOutputStream

The correct answer is: PrintWriter

The PrintWriter class is used to write data to a file in the BasicFileOutput example because it provides convenient methods for writing various types of data to a file. A FileWriter is used for writing character streams while a FileOutputStream is used for writing bytes. A BufferedWriter is used to buffer output and improve efficiency, but it does not directly write data to a file. Therefore, the correct answer is C because it specifically allows for writing data to a file in a convenient and efficient manner.
