PrintWriter is used to write data to a file, not read from it. The correct class to read data from a file is BufferedReader or Scanner. A is true as the JVM will throw an IOException if the file is missing. B is also true as the numbers in the file must be separated by whitespace characters, such as spaces, tabs or new lines. D is false as a special character is not required to mark the end of a text file.
