public final int read( byte b[] ) throws IOException
Parameters
- b
- the buffer into which the data is read.
Returns
the total number of bytes read into the buffer, or
-1 if there is no more data because the end
of the stream has been reached.
Description
Reads up to byte.length bytes of data from this data
input stream into an array of bytes. This method blocks until some
input is available.
The read method of DataInputStream
calls the read method of its underlying input stream
with the three arguments b, 0, and
b.length and returns whatever value that method returns.
Exceptions
IOException
if an I/O error occurs.
Overrides
read in class FilterInputStream

int len ) throws IOException
Parameters
- b

- off
- the start offset of the data.
- len
- the maximum number of bytes read.
Returns
the total number of bytes read into the buffer, or

of the stream has been reached.
Description
Reads up to len bytes of data from this data input
stream into an array of bytes. This method blocks until some input
is available.
The read method of DataInputStream
