Provides for system input and output through data streams.


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.
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.
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.
IOException Signals that an I/O exception of some sort has occurred.
InterruptedIOException Signals that an I/O operation has been interrupted.
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.
UnsupportedEncodingException The Character Encoding is not supported.
