void start() { A a = new A(); B b = new B(); a.s(b); b = null; /* Line 5 */ a = null; /* Line 6 */ System.out.println("start completed"); /* Line 7 */ } When is the B object, created in line 3, eligible for garbage collection?

There is no way to be absolutely certain.

void start() { A a = new A(); B b = new B(); a.s(b);
