Java in a Nutshell, 5th Edition [Electronic resources]

This class is a subclass of InputStream in which input data comes from a specified array of byte values. This is useful when you want to read data in memory as if it were coming from a file, pipe, or socket. Note that the specified array of bytes is not copied when a ByteArrayInputStream is created. See also CharArrayReader.
