## Name

EOFException

## Synopsis

Class Name:

  `java.io.EOFException`

Superclass:

  `java.io.IOException`

Immediate Subclasses:

  None

Interfaces Implemented:

  None

Availability:

  JDK 1.0 or later

## Description

An `EOFException` is thrown in response to an attempt to read past the end of a file.

Many file-handling routines indicate the end of a file with a special return code. For example, many `read()` methods return `-1` to indicate that the end of file has been reached. However, in some cases, the program clearly expects a certain format of data in a file. If it's not all there, throwing an exception is an appropriate way to flag the unusual condition of the file. So, for example, a `DataInputStream` throws an `EOFException` if it comes to the end of file in the middle of `readFloat()`. In the `java.io` package, `EOFException` is used in the classes that implement the `DataInput` and `ObjectInput` interfaces, namely `DataInputStream`, `ObjectInputStream`, and `RandomAccessFile`.
