An exception that occurs when reading from a stream or file, and indicates that the end of the stream has been reached. For example, you had expected to read 4 bytes from a stream with DataInputStream.readFully(), or an object with ObjectInputStream.readObject(), but end of stream was encountered instead.

For example, you had expected to read 4 bytes from a stream with DataInputStream.readFully(), or an object with ObjectInputStream.readObject(), but end of stream was encountered instead.
Even though the exception is named EOF for 'end of file', it is possible to get this exception when processing any data stream. The exception can occur as a result of many different actions, such as:
- Reading data from a socket connection that has already been closed by the peer and all prior pending data has already been read.
- Reading data from an empty file.
When reading from a stream, you should usually detect and handle this exception, as well as other stream-related exceptions such as timeouts, by wrapping your reads in a try-catch block. This will allow you to catch exceptions such as this, and perform an alternate operation, such as alerting the user of the error, or ending the logical connection at this end.
