Your code is not right, you have typing mistake.

Only 2 object will be created.

You can check by printing objects

---

public class Question {

int num;

public static void main(String[] args) {
Question b = foo();

System.out.println (b);

b.num = 5;

Question c = b;
c.num = 4;

System.out.println (c);

Object obj = c;

System.out.println(obj);

Question d = foo();

System.out.println(d);

d.num = b.num;
}

private static Question foo() {
return new Question();
}
}
