I would not recommend using it with classes using linear inheritance, where it's just useless overhead. As for chaining super::super, as i mentionned in the question, i have still to find an interesting use to that For now, i only see it as a hack, but it was worth mentioning, if only for the differences with java (where you can't chain super). Super e>) says that it's some type which is an ancestor (superclass) of e
Extends e>) says that it's some type which is a subclass of e (in both cases e itself is okay.) so the constructor uses the Extends e form so it guarantees that when it fetches values from the collection, they will all be e or some subclass (i.e I'm currently learning about class inheritance in my java course and i don't understand when to use the super() call
I found this example of code where super.variable is used
