I got tired of trying to make my .properties and .ini files look nice so now I delegated that to this object. It will order the output alphabetically, allows comments to be added to each property line, and allows for friendly white space in the output. It also provides several new i/o routines for writers, readers, or just passing it a filename. FileProperties does not make any attempt at recreating the comments for each property from the file when loading because of changes that may have occured in the file.
Previously my properties files would look something like this:

 # This is my web-based mail server properties file.  It containts all initialization parameters. # Sat Sept 23, 2000 database.password=password database.name=dbname database.user=user threads.max_number=20 database.port=9898 
 
 Now I can get them to look like this: 
 # This is my web-based mail server properties # file.  It contains all the initialization # parameters. # Generated on: Sat Sept 23, 2000 # The name of the database instance we are # connection to. database.name=dbname # The password used when connection to the # databse. database.password=dbpassword # The port number to connect to the database # on. database.port=9999 # The name of user to use to connect to the # database database.user=dbuser # The maximum number of threads ever running # for this app.  If set to low this will # prevent concurrent sessions.  If set to high # it might bog down the system with unecessary # threads threads.max_number=20
