     And your problem with this is ...?  Perhaps I'm just being
dense today, but I don't see the difficulty.  If you know that
columns 0 and 1 hold integers, use `new Integer(data[0])' or
`Integer.parseInt(data[1])'.  For the remaining columns use
`new Double(data[2])' or `Double.parseDouble(data[3])'.  In
both cases, you can try/catch NumberFormatException to detect
trouble if desired.

     If you just want to rearrange the data and don't need to
validate it, most of the conversions may be unnecessary anyhow.
I guess you'll want to convert the first two columns and build
a Calendar object from them (it's easy to keep adding six-hour
intervals to a Calendar), but you could just take the remaining
columns as strings, outputting them in the same form they were
read.
