I know the Prefernce Class was used to storage persistent,But the

Preference Class is an abstract Class ,it can't be instanced. The

GreneralPreference class extends the Preference ,provides some

standardized preferences--"Default Font Size".The other case ,the user

want to define the other preferences--"Z_wolf" ,that the

GreneralPreference class is not provide.
The Code:
GreneralPreference GPreference = new GreneralPreference("Z-wolf");

When I debug the program,the result hint that the "Z_wolf"

preference's name was not supported. Are there anybody tell me the cause .
Are there anybody tell me the cause of the storage persistent in mhp ,and how to extend Preferences class.
