### Uses of Flushable in java.io

Classes in java.io that implement Flushable
`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.
`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.

### Uses of Flushable in java.rmi.server

### Uses of Flushable in java.util

Classes in java.util that implement Flushable
`class` `Formatter` An interpreter for printf-style format strings.

### Uses of Flushable in java.util.jar

Classes in java.util.jar that implement Flushable
`class` `JarOutputStream` The `JarOutputStream` class is used to write the contents of a JAR file to any output stream.

### Uses of Flushable in java.util.zip

Classes in java.util.zip that implement Flushable
`class` `CheckedOutputStream` An output stream that also maintains a checksum of the data being written.
`class` `DeflaterOutputStream` This class implements an output stream filter for compressing data in the "deflate" compression format.
`class` `GZIPOutputStream` This class implements a stream filter for writing compressed data in the GZIP file format.
`class` `InflaterOutputStream` Implements an output stream filter for uncompressing data stored in the "deflate" compression format.
`class` `ZipOutputStream` This class implements an output stream filter for writing files in the ZIP file format.

### Uses of Flushable in javax.crypto

Classes in javax.crypto that implement Flushable
`class` `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.

Subinterfaces of Flushable in javax.tools
`interface` `JavaFileManager` File manager for tools operating on Java™ programming language source and class files.
`interface` `StandardJavaFileManager` File manager based on java.io.File and java.nio.file.Path.

Classes in javax.tools that implement Flushable
`class` `ForwardingJavaFileManager<M extends JavaFileManager>` Forwards calls to a given file manager.
