I was reading abt the Garbage Collection policy of Java. I read that we dont need to use destructors coz of this policy.
The author wrote that the objects are destroyed when they are no longer needed...but this does not happen when an object goes out of scope.

The Ques...
What is the diff between two cond??

[furtivefelon]

huh? when the object goes out of scope, it means nothing can asscess it anymore, which means it is useless to remain in the program.. thus is destroyed.. what's the problem?

Thts what I am trying to tell..Objects are not destroyed when they go out of scope..They are dest when not needed, there i a diff bet two cond.
I want to know abt that!!

They are dest when not needed

Correct. Garbage collection is the process of freeing memory when an object is no longer referenced by a program. That's the bottom line. You're making this more difficult than it is.

Well, if its like .NET, an object is destroyed on a periodic schedule.

Many objects may go out of scope, and they are marked as unused, and a garbage collector will periodically come through and free all the memory.

This keeps down the overhead of garbage collection. For instance if you were making recursive calls, when the recursion unwound, you don't want a garbage collector being called potentionall hundreds or thousands of times in a row to free memory. It can be marked unused and removed later. (When the CPU isn't very busy)
