Basically all variables of type Object are actually pointers to an Object.
So with
String s = "Java";
s is actualy a pointer pointing to the location of the String.

AHA Thomas!! Caught ya!
You KNOW that it says in the fine print of the JLS
[non-quote]
Thou shalt NOT use the word pointer as a synonym for a reference in JAVA.
[end-non-quote]
Even though a variable holds an address or reference to the location of an object in java, it does not have the same ability to be manipulated the way a pointer in c does. Therefore it is dangerous to use the word pointer in any context in java.
