Java garbage collection question

Hi,

while drawing GV diagram , i can see that only one object is eligible for GC but the answer gives 2. CAn you plz check:

class A{
	  A aob;
	  public static void main(String args[]){
	    A a=new A();
	    A b=new A();
	    A c=new A();
	    a.aob=b;
	    b.aob=a;
	    c.aob=a.aob;
	    A d=new A().aob=new A();
	    c=b;
	    c.aob=null;
	    System.gc();
	  }
}

Hi Vikram,

There ARE two objects eligible for the garbage collector. Namely, the object created at the line-6, and one of the two objects created at line-10 becomes eligible at the end of the given code fragment. Solving this sorta questions would be much easy if you watch our garbage collection video:

Can you please let me see the diagram you created so we can figure out where you had a problem on?
