Answer 3

An important thing to know about I/O in Java is that streams ( InputStream and OutputStream etc.) are used for reading and writing binary data (you read or write bytes exactly as they are in the file), and readers and writers ( Reader and Writer etc.) are for reading and writing characters.

Readers and writers are a layer on top of streams. A Reader interprets the bytes from an InputStream using a character encoding (such as UTF-8, ISO-8859-1, US-ASCII) to convert them into characters, and a Writer uses a character encoding to turn characters into bytes.
