In the Da Vinci code, its supposed to be Mary Magdalene's womb. The Chalice is a feminine symbol, therefore; the bible's words could be interpreted as Mary.
The traditional idea is that when Jesus was sharing his last supper with his disciples, he gave them bread and told them it was his body. He gave them wine and said it was his blood. The goblet this wine was in was the Grail… i think? i'm not christian.
I have also heard that the Grail supposedly grants immortality and crap to whomever drinks from it.

These are standard Unified Modelling Language terms for the possible types of relationships between classes in an object-oriented design methodology. NetBeans is an IDE that allows you to implement programmes in Java. As Java is an OO language, the UML terms are therefore referred to within NetBeans. The following on Wikipedia will explain the terms if you are familiar with OO / UML. If not, you really need to read up on that first:

you have to show him that you're the 'food fairy.'
put down a LITTLE bit of kibble (when it's feeding time) and let him eat.
when he's done with that, he'll probably look at you wanting asking 'is that it?'
then take the food bowl away, add more kibble, then set it back down.
and keep doing that until he got all the food he needed to eat.
(oh and always be right next to him while he's eating…but don't try to touch him.)

soon he'll realize that he's dependent on YOU for food.

then try giving him a treat and petting him after you've done the food thing for awhile. see if he'll still growl at you then.

if he does, repeat the process a couple more times.

hopefully this'll help.

They're not really saying anything. It's just a tune.
