Interface Summary

Interface	Description
Closeable	A Closeable is a source or destination of data that can be closed.
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.
FileFilter	A filter for abstract pathnames.
FilenameFilter	Instances of classes that implement this interface are used to filter filenames.
Flushable	A Flushable is a destination of data that can be flushed.
Serializable	This interface is only defined for hierarchy compatibility.

Class Summary

Class	Description
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 output stream lets an application write primitive Java data types to an output stream in a portable way.
File
FileInputStream	A FileInputStream obtains input bytes from a file in a file system.
FileOutputStream	A file output stream is an output stream for writing data to a File.
FilePermission
FilterInputStream	A FilterInputStream contains some other input stream, which it uses as its basic source of data, possibly transforming the data along the way or providing additional functionality.
FilterOutputStream	This class is the superclass of all classes that filter output streams.
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 decodes them into characters using a specified charset.
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 encoded into bytes using a specified charset.
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

Exception	Description
EOFException	Signals that an end of file or end of stream has been reached unexpectedly during input.
FileNotFoundException
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 string in modified UTF-8 format has been read in a data input stream or by any class that implements the data input interface.
