Garbage Collection

[mukki pandey]

public class BettyAck {
public static void main(String argv[]){
BettyAck b =new BettyAck();
}
public BettyAck() {
Integer x = new Integer(10);
findOut(x);
Integer y = new Integer(99);
Integer z = y;
z = null;
findOut(y);
//here
}
public void findOut(Integer y){
y = null;

}
}


Given the following code, how many objects will be eligible for garbage collection on the line with the comment //here

[Lakshman Arun]

No object is eligible for GC at line //here

[Ankit Garg]

mukki please tell from where you copied this question!!!

[sweety sinha]

i think Lakshman Arun is wright

[mukki pandey]

i got from esnips pdf

but isn't b available for GC...because it is not set to null

[vipin jain]

No object is eligible for GC at line //here

[mukki pandey]

how about this

BettyAck b =new BettyAck();

isn't b available for GC

[ramesh maredu]

BettyAck b =new BettyAck();
 
isn't b available for GC 

b is a reference variable, reference variables are never eligible for GC.The object created(new BettyAck()) is also not eligible for GC,as it has reference from b.

[Arabinda Das]

we have not lost the reference of 'b' object till now. so its not available for GC
