- ## Uses of DataInput in java.io

  Subinterfaces of DataInput in java.io
  Modifier and Type
  Interface
  Description
  `interface`
  `ObjectInput`
  ObjectInput extends the DataInput interface to include the reading of objects.
  Classes in java.io that implement DataInput
  Modifier and Type
  Class
  Description
  `class`
  `DataInputStream`
  A data input stream lets an application read primitive Java data types from an underlying input stream in a machine-independent way.
  `class`
  `ObjectInputStream`
  An ObjectInputStream deserializes primitive data and objects previously written using an ObjectOutputStream.
  `class`
  `RandomAccessFile`
  Instances of this class support both reading and writing to a random access file.
  Methods in java.io with parameters of type DataInput
  Modifier and Type
  Method
  Description
  `static final String`
  DataInputStream.`readUTF(DataInput in)`
  Reads from the stream `in` a representation of a Unicode character string encoded in modified UTF-8 format; this string of characters is then returned as a `String`.

- ## Uses of DataInput in java.rmi.server

  Methods in java.rmi.server with parameters of type DataInput
  Modifier and Type
  Method
  Description
  `static UID`
  UID.`read(DataInput in)`
  Constructs and returns a new `UID` instance by unmarshalling a binary representation from an `DataInput` instance.

  An abstract class implementing the `ImageInputStream` interface.
  `class`
  `ImageOutputStreamImpl`
  An abstract class implementing the `ImageOutputStream` interface.
  `class`
  `MemoryCacheImageInputStream`
  An implementation of `ImageInputStream` that gets its input from a regular `InputStream`.
  `class`
  `MemoryCacheImageOutputStream`
  An implementation of `ImageOutputStream` that writes its output to a regular `OutputStream`.
