Answer Posted / harish
Garbage Collection is carried out based on the reference
type an object is currently in.
There are 4 types of references in java
1)strong reference
2)soft reference
3)weak reference
4)phantom reference
the last one is the weakest of the weak.
JVM will try get all those of object that are fell in this
category and try to collect it.
But it is not neccessary the object in phantom reference
phase will always be garbage collected.
