Java – what is a good way to keep application properties?

I have a series of application properties, all of which have different types

Types can include Boolean values, dates, timestamps, or strings

I need to be able to provide administrative users with the ability to change these attributes and let the system remember / save them to a file

I'm looking for a best practice way to store these application properties and be able to keep them when they change and load them at startup

Java has tools built specifically for this purpose - properties This is a very good article about it
