Known indirect subclasses

AssetFileDescriptor.AutoCloseOutputStream, Base64OutputStream, BufferedOutputStream, BufferedWriter, ByteArrayOutputStream, CharArrayWriter, CheckedOutputStream, CipherOutputStream, Console, DataOutputStream, DeflaterOutputStream, DigestOutputStream, FileOutputStream, FileWriter, FilterOutputStream, and 16 others.

AssetFileDescriptor.AutoCloseOutputStream	An OutputStream you can create on a ParcelFileDescriptor, which will take care of calling `ParcelFileDescriptor.close()` for you when the stream is closed.
Base64OutputStream	An OutputStream that does Base64 encoding on the data written to it, writing the resulting data to another OutputStream.
BufferedOutputStream	The class implements a buffered output stream.
BufferedWriter	Writes text to a character-output stream, buffering characters so as to provide for the efficient writing of single characters, arrays, and strings.
ByteArrayOutputStream	This class implements an output stream in which the data is written into a byte array.
CharArrayWriter	This class implements a character buffer that can be used as an Writer.
CheckedOutputStream	An output stream that also maintains a checksum of the data being written.
CipherOutputStream	A CipherOutputStream is composed of an OutputStream and a Cipher so that write() methods first process the data before writing them out to the underlying OutputStream.
Console	Methods to access the character-based console device, if any, associated with the current Java virtual machine.
DataOutputStream	A data output stream lets an application write primitive Java data types to an output stream in a portable way.
DeflaterOutputStream	This class implements an output stream filter for compressing data in the "deflate" compression format.
DigestOutputStream	A transparent stream that updates the associated message digest using the bits going through the stream.
FileOutputStream	A file output stream is an output stream for writing data to a `File` or to a `FileDescriptor`.
FileWriter	Writes text to character files using a default buffer size.
FilterOutputStream	This class is the superclass of all classes that filter output streams.
FilterWriter	Abstract class for writing filtered character streams.
Formatter	An interpreter for printf-style format strings.
GZIPOutputStream	This class implements a stream filter for writing compressed data in the GZIP file format.
InflaterOutputStream	Implements an output stream filter for uncompressing data stored in the "deflate" compression format.
JarOutputStream	The `JarOutputStream` class is used to write the contents of a JAR file to any output stream.
ObjectOutputStream	An ObjectOutputStream writes primitive data types and graphs of Java objects to an OutputStream.
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`.
ParcelFileDescriptor.AutoCloseOutputStream	An OutputStream you can create on a ParcelFileDescriptor, which will take care of calling `ParcelFileDescriptor.close()` for you when the stream is closed.
PipedOutputStream	A piped output stream can be connected to a piped input stream to create a communications pipe.
PipedWriter	Piped character-output streams.
PrintStream	A `PrintStream` adds functionality to another output stream, namely the ability to print representations of various data values conveniently.
PrintWriter	Prints formatted representations of objects to a text-output stream.
StringWriter	A character stream that collects its output in a string buffer, which can then be used to construct a string.
Writer	Abstract class for writing to character streams.
ZipOutputStream	This class implements an output stream filter for writing files in the ZIP file format.

A Flushable is a destination of data that can be flushed. The flush method is invoked to write any buffered output to the underlying stream.

Summary

Public methods
`abstract void`	`flush()` Flushes this stream by writing any buffered output to the underlying stream.

Public methods

flush

Added in API level 1

public abstract void flush ()

Flushes this stream by writing any buffered output to the underlying stream.

Throws
`IOException`	If an I/O error occurs
