Variable accessible to all instances of a class

Let's say I have a lookup table which I'd like to make accessible to 开发者_StackOverflowall instances of Foo. Should I make the table private static? If not, what should I do?

Basically I want a way to save just one copy of the table (so it doesn't consume extra memory for each instance of Foo) and have it available privately to all instances of Foo.

That sounds like private static to me.
