## Uses of Interface
java.io.DataOutput

Packages that use DataOutput
java.io | Provides for system input and output through data streams, serialization and the file system.
java.rmi.server | Provides classes and interfaces for supporting the server side of RMI.
javax.imageio.stream | A package of the Java Image I/O API dealing with low-level I/O from files and streams.

Uses of DataOutput in java.io

Subinterfaces of DataOutput in java.io
`interface` | `ObjectOutput` ObjectOutput extends the DataOutput interface to include writing of objects.

Classes in java.io that implement DataOutput
`class` | `DataOutputStream` A data output stream lets an application write primitive Java data types to an output stream in a portable way.
`class` | `ObjectOutputStream` An ObjectOutputStream writes primitive data types and graphs of Java objects to an OutputStream.
`class` | `RandomAccessFile` Instances of this class support both reading and writing to a random access file.

Uses of DataOutput in java.rmi.server

Methods in java.rmi.server with parameters of type DataOutput
`void` | `UID.write(DataOutput out)` Marshals a binary representation of this `UID` to a `DataOutput` instance.

Uses of DataOutput in javax.imageio.stream

Subinterfaces of DataOutput in javax.imageio.stream
`interface` | `ImageOutputStream` A seekable output stream interface for use by `ImageWriter`s.

Classes in javax.imageio.stream that implement DataOutput
`class` | `FileCacheImageOutputStream` An implementation of `ImageOutputStream` that writes its output to a regular `OutputStream`.
`class` | `FileImageOutputStream` An implementation of `ImageOutputStream` that writes its output directly to a `File` or `RandomAccessFile`.
`class` | `ImageOutputStreamImpl` An abstract class implementing the `ImageOutputStream` interface.
`class` | `MemoryCacheImageOutputStream` An implementation of `ImageOutputStream` that writes its output to a regular `OutputStream`.
