## 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.
