But the main advantage comes with multiple inheritance, where all sorts of fun stuff can happen. Why would you need to use super? Super() is a special use of the super keyword where you call a parameterless parent constructor
Super
In general, the super keyword can be used to call overridden methods, access hidden fields or invoke a superclass's constructor.
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. 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
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 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).
Wanting to call super.super.tostring() contradicts your own decision when you choose to extend a class thus accepting all (not some of) its features.
Things to know about python super [2 of 3] (this one specifically covers unbound super) things to know about python super [3 of 3] also, he argues strongly for removing unbound super from python 3 here I said you were calling it incorrectly (though correctness is largely meaningless without context, and a toy example doesn't give much context). When do you call super() in java I see it in some constructors of the derived class, but isn't the constructors for each of the parent class called automatically
