object reference variables as literals?

[Maddison]

Hi
One of the JCJAP exam objectivies is:

Develop code that uses primitives, enumeration types, and object references, and recognize literals of these types.

what is a literal value of an object reference?

thanks

null

[Steve Morrow]

null

That's one. A String literal is a reference to a String object. The .class literal is a reference to a Class object.

Hope this helps!

Iam Sorry. I don't get you. How do you say It's null??
