Uses of Reader in java.io

 

Subclasses of Reader in java.io
class	BufferedReader           Read text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines.
class	CharArrayReader           This class implements a character buffer that can be used as a character-input stream.
class	FileReader           Convenience class for reading character files.
class	FilterReader           Abstract class for reading filtered character streams.
class	InputStreamReader           An InputStreamReader is a bridge from byte streams to character streams: It reads bytes and translates them into characters according to a specified character encoding.
class	LineNumberReader           A buffered character-input stream that keeps track of line numbers.
class	PipedReader           Piped character-input streams.
class	PushbackReader           A character-stream reader that allows characters to be pushed back into the stream.
class	StringReader           A character stream whose source is a string.

 

Fields in java.io declared as Reader
protected  Reader	FilterReader.in           The underlying character-input stream, or null if the stream has been closed
