| Every time, when we create new X() we make not 1, but 2 objects (because one more object create in line 3 ). That's why after line 11, we are eligible for garbage collection 2 object. P.S. Sorry for my English :) |

| Ans: 2 Object are garbage collected. Because, public X2 x; public static void main(String [] args) { X2 x2 = new X2(); /* Line 6 */ X2 x3 = new X2(); /* Line 7 */ x2.x = x3; x3.x = x2; x2 = new X2(); x3 = x2; /* Line 11 */ doComplexStuff(); } Here the statement (x2.x = x3;) will hold new X2() object. And when x variable of type X hold another object called x2 at that moment one object garbage collected. G: x3 because one variable will hold one address. Not more than one variable. And another object got garbage collected at the moment when we call x2 = new X2() ; So total 2 object got garbage collected. |

| The correct answer is C. after main() We assign the class X2's reference-id to x2(X2 x2=new X2()). After it, we again assigning the reference-id of 2 to x3(X2 x3=new X2()). So,x2 become eligible for GC. Just before line 11 again reference-id of class X2 is going to x2 (x2=new X2). therefor now x3 become eligible for GC. That's why the answer is C. |
