super () in Java - Stack Overflow super() is a special use of the super keyword where you call a parameterless parent constructor In general, the super keyword can be used to call overridden methods, access hidden fields or invoke a superclass's constructor
Understanding Python super() with __init__() methods super() lets you avoid referring to the base class explicitly, which can be nice But the main advantage comes with multiple inheritance, where all sorts of fun stuff can happen
How does Pythons super () work with multiple inheritance? 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
coding style - Using super in C++ - Stack Overflow 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")
Difference between superkey and composite key - Stack Overflow 4 Super Key: If you add any other column attribute to a Primary Key then it become a super key, like EmployeeID + FullName is a Super Key 5 Composite Key: If a table don't have any individual columns that qualifies for a Candidate key, then you have to select 2 or more columns to make a row unique
java - how to Call super constructor in Lombok - Stack Overflow The only workaround I found is to declare all members final yourself and use the @Data annotation instead Those subclasses need to be annotated by @EqualsAndHashCode and need an explicit all args constructor as Lombok doesn't know how to create one using the all args one of the super class:
java - What is lt;? super T gt; syntax? - Stack Overflow super in Generics is the opposite of extends Instead of saying the comparable's generic type has to be a subclass of T, it is saying it has to be a superclass of T The distinction is important because extends tells you what you can get out of a class (you get at least this, perhaps a subclass) super tells you what you can put into the class (at most this, perhaps a superclass) In this
AttributeError: super object has no attribute - Stack Overflow I wrote the following code When I try to run it as at the end of the file I get this stacktrace: AttributeError: 'super' object has no attribute do_something class Parent: def __init__(self):
Why do this () and super () have to be the first statement in a . . . The automatic insertion of super () by the compiler allows this Enforcing super to appear first, enforces that constructor bodies are executed in the correct order which would be: Object -> Parent -> Child -> ChildOfChild -> SoOnSoForth
