This class is a subclass of
InputStream that reads bytes from a file specified
by name or by a File or
FileDescriptor object. read( )
reads a byte or array of bytes from the file. It returns -1 when the
end-of-file has been reached. To read binary data, you typically use
this class in conjunction with a
BufferedInputStream and
DataInputStream. To read
text, you typically use it
with an InputStreamReader and
BufferedReader. Call close(
)
to close the file when input is no longer needed.In Java 1.4 and later, use getChannel(
)
to obtain a
FileChannel object for reading from the underlying
file using the New I/O API of java.nio and its
subpackages.
