b - the byte array to read into

Returns:

the number of bytes read or -1 if the end of the stream has been reached

Throws:

IOException - if an I/O error occurs

read

public int read()
         throws IOException

Read a single byte.

Specified by:

read in class InputStream

Returns:

either the byte read or -1 if the end of the stream has been reached

Throws:

IOException - if an I/O error occurs

close

public void close()
           throws IOException

Close the stream.

Specified by:

close in interface Closeable

Specified by:
