In Quiz 6 Qns 22, why this this False? image

What if the object was de-referenced in the newGame() function, something like:

Minefield minefield = new Minefield();
... ... ...
Minefield minefield2 = new Minefield();
minefield  = minefield2;

Won't the first minefield object be de-referenced and deleted? Or is it because there activation bar for the Minefield constructor is wrong and therefore the entire thing is wrong?

The problem is that the lifeline must not continue past the X. https://nus-cs2103-ay2324s2.github.io/website/se-book-adapted/chapters/uml.html#object-deletion
