Writing Little Endian Binary Data (Was: Long in the...)

["Scott P. Smith" <ssmith@scott-smith.com>]

Rob,

Someone mentioned the Apache POI project earlier.  The org.apache.poi.util
package in that project has what you need, I think.  That project has do to
all the kind of stuff you are doing, so the code is there somewhere. Look at
the org.apache.poi.util.LittleEndian class.  It reads (and writes) different
primitive data types from (to) a byte array.  Of course, you would use this
class in combination with a java.io.BufferedInputStream and/or a
java.io.BufferedOutputStream.
