How many objects are Garbage Collected

[rengarajan vaikuntam]

Code is:

import java.util.*;
public class Collectionss {
public static void main(String as[]) {
LinkedList lhs = new LinkedList();
Collectionss c = new Collectionss();
Collectionss c1 = new Collectionss();
lhs.add(c1);
lhs.add(c);
lhs.add("ma");
lhs.add("ba");
lhs.add("co");
lhs.add("de");
//lhs=null;
Iterator it = lhs.iterator();
//it.remove("delhi");
while(it.hasNext()){
System.out.println("CITY IS"+it.next());
}
lhs=null;
}
}

How many objects are garbage collected in this code after the line
lhs=null;
Could anyone explain me.
Thanks.

Here, only object "LinkedList" is garbage collected. Even after lhs=null, c and c1 are still pointing to Collectionss objects. In Java strings are also objects so you can say strings "ma", "ba", "co" and "de" are also garbage collected!

Hope it helps.

Nitin
so can we say five objects are garbage collected.

[Veena Pointi]

Yeah I guess 5 objects. lhs,"ma","ba","co","de"

Rengarajan, you are right !

What about the Iterator reference it.What will it refer to initially and after the while loop??

I have a doubt.

The String Objects are created in ' String pool'. (ma,ba,co,de).
Whether they are eligible for GC.? Or they are neglected by GC?
