But you know what, I think combining String Objects and a question about Garbage Collection together is just mean. It ends up asking about two seperate things.
1. Garbage Collection
2. Which Strings are in the String Pool and which are Objects on the heap.

b) 1 --> "Nick" is the only object which does not have a stack variable reference pointing to it. The other Strings have references to them.

String newName = "Nick";
newName = "Jason";
name = "Frieda";
String newestName = name;
name = null;

I think
< (b) 1 > is correct.
As there were only 3 objects and 2 are being referenced.
So its "NICK" which is eligible for garbage collection.
further u can't take name as object its only reference variable.

Right if newestName didnt refer to the object refer by name then doing name=null wd make 2 objects elegible for GC. Thanks !

For what its worth, I agree with Rubens and Arvind. "Nick" appears to be the only String object not referenced.
Are we right? Can I have my certificate now?
