Hi:George and Andrew
I have finished my Data class and
test it run better.
my question is :
I create DataSchema class and get the metadata of the database.and i put this in Data class.I also create ServicesImpl class for booking and searching.
whether i can create public method in Data class(public DataSchema getDataSchema())and used in ServicesImpl? also in Data class,whether i can create myself public method but the methods that sun provides?
please give me some suggestions.
