Updating Properties file

Hi Ranchers,

I want to update the properties file without changing the sequence of key,value pairs.
When I do it using Java.util.Proeprties.setProperty , the format of file is lost, although the data gets persisted.

Is there any way out ?

Thanks in advance

SCJP 1.4,SCBCD 1.3, SCWCD 1.5, ???

You could extend the Properties with your own class that overrides the "load" and "store" method with versions that remember (load) and honor (store) the order of the original file. If you start with the code of the original methods, that shouldn't be too hard.
I agree. Here's the link:
