Classes in java.io that implement Flushable
Modifier and Type
Class
Description
`class`
`BufferedOutputStream`
The class implements a buffered output stream.
`class`
`BufferedWriter`
Writes text to a character-output stream, buffering characters so as to provide for the efficient writing of single characters, arrays, and strings.
`class`
`ByteArrayOutputStream`
This class implements an output stream in which the data is written into a byte array.
`class`
`CharArrayWriter`
This class implements a character buffer that can be used as an Writer.
`final class`
`Console`
Methods to access the character-based console device, if any, associated with the current Java virtual machine.
`class`
`DataOutputStream`
A data output stream lets an application write primitive Java data types to an output stream in a portable way.
`class`
`FileOutputStream`
A file output stream is an output stream for writing data to a `File` or to a `FileDescriptor`.
`class`
`FileWriter`
Writes text to character files using a default buffer size.
`class`
`FilterOutputStream`
This class is the superclass of all classes that filter output streams.
`class`
`FilterWriter`
Abstract class for writing filtered character streams.
`class`
`ObjectOutputStream`
An ObjectOutputStream writes primitive data types and graphs of Java objects to an OutputStream.
`class`
`OutputStream`
This abstract class is the superclass of all classes representing an output stream of bytes.
`class`
`OutputStreamWriter`
An OutputStreamWriter is a bridge from character streams to byte streams: Characters written to it are encoded into bytes using a specified `charset`.
`class`
`PipedOutputStream`
A piped output stream can be connected to a piped input stream to create a communications pipe.
`class`
`PipedWriter`
Piped character-output streams.
`class`
`PrintStream`
A `PrintStream` adds functionality to another output stream, namely the ability to print representations of various data values conveniently.
`class`
`PrintWriter`
Prints formatted representations of objects to a text-output stream.
`class`
`StringWriter`
A character stream that collects its output in a string buffer, which can then be used to construct a string.
`class`
`Writer`
Abstract class for writing to character streams.
