What does the PrintWriter class provide?

  1. Formatted input

  2. Formatted output

  3. Byte manipulation

  4. Binary data storing

The correct answer is: Formatted output

The PrintWriter class provides a set of methods for writing formatted data to an output stream, such as a file. This allows for more organized and easily readable output, as opposed to writing each individual piece of data separately with regular output streams. Options A, C, and D are incorrect because the PrintWriter class does not provide input or manipulation of bytes or binary data storage. Its main function is for formatted output.
