Hello Folks,

Pls read the following garbage collection information and let me know how obj2 is eligible for garbage collection.

"If an Object Obj1 is garbage collected, but another object obj2 contains a reference to it, then obj2 is also eligible for garbage collection"

Thanks, Raghu.K

An object can only be garbage collected if it cannot be referenced from the "active" part of the program.

So if obj1 is garbage collected, this means it cannot be referenced from the active part of the program. Now, if obj2 could be referenced from the active part of the program, then this would provide a way to reference obj1 from the active part of the program. But we know this is not possible, because obj1 is garbage collected. Therefore, it must be that obj2 cannot be referenced from the active part of the program, and so obj2 is eligible for garbage collection.
