This library provides an easy wrapper for java properties that can be used to save any setting or string on the users hard disk and find it later again. Each class gets its own property file that is saved in the applications AppData folder. Make sure to initialize the library before doing anything else, see the getting started page.

Next, initialize your preferences file by creating a new instance of the Prefs-class:

// if you are in a non-static method
Prefs prefs = new Prefs(this.getClass().getName());
// if you are in a static method
Prefs prefs = new Prefs(MyClass.class.getName());

Now just use

prefs.public void setPreference(prefKey, prefValue);

and

prefs.getPreference(prefKey, defaultValue);

to save and retreive preferences.
