I understood that strings were put in the string pool and therefore not GC'd?

[admin]

Not all strings fall into that category. If you create a string using new e.g. new String("xyz"), there are actually two string objects created, one instantiated in a string pool (which cannot be GCed) and another one in the heap (which can be GCed).

Hi, we should not consider the "" as collectible?

thanks.

That depends on whether it is a literal or now.
String s = ""; //not collectible.
String s = new String(""); //collectible.
