Given:
3. interface Animal { void makeNoise(); }
4. class Horse implements Animal {
5. Long weight = 1200L;
6. public void makeNoise() { System.out.println("whinny"); }
7. }
8. public class Icelandic extends Horse {
9. public void makeNoise() { System.out.println("vinny"); }
10. public static void main(String[] args) {
11. Icelandic i1 = new Icelandic();
12. Icelandic i2 = new Icelandic();
13. Icelandic i3 = new Icelandic();
14. i3 = i1; i1 = i2; i2 = null; i3 = i1;
15. }
16. }
When line 15 is reached, how many objects are eligible for the garbage collector?
De acordo com o livro a resposta correta é 4.
Pelo q entendi seriam as 3 instancias de Icelandic e o objeto weigth, mas pq só 4, e não 6? 3 Icelandics e 3 weigths?
