The class that can return more than one character to the input stream is the PushbackReader class.

Here's why:

1. BufferedWriter: This class is used to write text to a character-output stream, buffering characters so as to provide for the efficient writing of single characters, arrays, and strings. It doesn't have the ability to return characters to the input stream.

2. BufferedReader: This class reads text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines. While it does have a method to "unread" characters, it's limited to a single character.

3. PushbackReader: This class adds functionality to another instance of the Reader class. It allows one to "unread" characters (push them back into the stream). It can "unread" multiple characters, which makes it the correct answer.

4. CharArrayReader: This class is used to implement a character buffer that can be used as a character-input stream. It doesn't have the ability to return characters to the input stream.
