In general, the super keyword can be used to call overridden methods, access hidden fields or invoke a superclass's constructor. 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). In fact, multiple inheritance is the only case where super() is of any use I would not recommend using it with classes using linear inheritance, where it's just useless overhead. 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 How do i call the parent function from a derived class using c++ For example, i have a class called parent, and a class called child which is derived from parent Within each class there is a print
When i try to run it as at the end of the file i get this stacktrace 'super' object has no attribute do_something class parent 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 Or render arbitrary text as super or subscript inline, eg And so it was indeed
