Grading comment:

Suppose we have a Dog class where each Dog has a name and a weight. Suppose we are trying to create the hashCode for our Dog class. Which of the two hashCodes below would guarantee to result in the two equivalent Dog objects, d$1$ and d$2,$ being hashed to the same bucket in our hash table?

Dog d$1=$ new Dog$("$Zeus$",5)$;

Dog d$2=$ new Dog$("$Zeus$",5)$;

public int hashCode$1()\{$

return $($int$)($Math$.$random$()*20)+1$;

$\}$

public int hashCode$2()\{$

return $($int$)$this$.$name.length$()$;

$\}$

Choice $1$ of $2$:hashCode$1()$

Choice $2$ of $2$:hashCode$2()$
