The programmer's misunderstanding of the general contract of the read() methods can result in failure to read the intended data in full. ..it It is possible for that the data to be is less than 1024 bytes long, with additional data available from the InputStream.

The no-argument and one-argument readFully() methods of the DataInputStream class guarantee that they either will read all of the requested data or will throw an exception. These methods throw EOFException if they detect the end of input before the required number of bytes have been read; they throw IOException if some other input/output error occurs.
