Explanation/Reference:
Explanation:
(this == obj) is the object implementation of equals() and therefore FALSE, if the reference points to
various objects and then the super.equals() is invoked, the object method equals() what still result in
FALSE better override of equals() is to compare the attributes like:
public boolean equals (Object obj) {
if (obj != null){
Product p = (Product)obj;
return this.id == p.id;
}
return false;
}
