garbage collection

[mita]

Hi,
The objects those have no more reference or set to null are garbage collected.
Is there any specific rule for String objects which are created by new String statement to be garbage collected.Because it creates two objects one in the heap and one in the pool.
And how the String LITERALS are garbage collected.
Someone please explain.
Thank you.

Mita,
The objects that are new'ed, are created on the Heap and are garbage collected using the 'zero reference' rule. This is an important concept for SCJP, so make sure you understand it well.
The objects created in the String pool are not subjected to GC until the class is unloaded by the JVM. They get discarded at the time, or just before the virtual machine unloads the class bytecode. For the purpose of the SCJP exam, you are not required to know the details of String pool memory management.
Hope this helps,
Ajith
