Package java.io

Provides for system input and output through data streams.

See:
Description

Interface Summary

DataInput	The DataInput interface provides for reading bytes from a binary stream and reconstructing from them data in any of the Java primitive types.
DataOutput	The DataOutput interface provides for converting data from any of the Java primitive types to a series of bytes and writing these bytes to a binary stream.

Class Summary

ByteArrayInputStream	A ByteArrayInputStream contains an internal buffer that contains bytes that may be read from the stream.
ByteArrayOutputStream	This class implements an output stream in which the data is written into a byte array.
DataInputStream	A data input stream lets an application read primitive Java data types from an underlying input stream in a machine-independent way.
DataOutputStream	A data input stream lets an application write primitive Java data types to an output stream in a portable way.
InputStream	This abstract class is the superclass of all classes representing an input stream of bytes.
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.
OutputStream	This abstract class is the superclass of all classes representing an output stream of bytes.
OutputStreamWriter	An OutputStreamWriter is a bridge from character streams to byte streams: Characters written to it are translated into bytes according to a specified character encoding.
PrintStream	A PrintStream adds functionality to another output stream, namely the ability to print representations of various data values conveniently.
Reader	Abstract class for reading character streams.
Writer	Abstract class for writing to character streams.

Exception Summary

EOFException	Signals that an end of file or end of stream has been reached unexpectedly during input.
InterruptedIOException	Signals that an I/O operation has been interrupted.
IOException	Signals that an I/O exception of some sort has occurred.
UnsupportedEncodingException	The Character Encoding is not supported.
UTFDataFormatException	Signals that a malformed UTF-8 string has been read in a data input stream or by any class that implements the data input interface.
