What does the FileWriter class do?

  1. Writes bytes to a file

  2. Writes characters to a file

  3. Reads characters from a file

  4. Reads bytes from a file

The correct answer is: Writes characters to a file

The FileWriter class is specially designed for writing characters to a file. It is used to write text to a character-based output stream, making it unsuitable for writing bytes to a file. The other options are incorrect because they do not accurately describe the purpose of the FileWriter class. FileWriter is not used for reading characters or bytes from a file, but rather for writing data to a file. Therefore, the correct answer is B.
