  • Why is super. super. method (); not allowed in Java?
    If your object doesn't fit in it's super class, then you need to add it to the "grandparent class", create a new class, or find another super it does fit into Personally, I have found this limitation to be one of Java's greatest strengths Code is somewhat rigid compared to other languages I've used, but I always know what to expect
  • 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
  • What is a difference between lt;? super E gt; and lt;? extends E gt;?
    The first (<? super E>) says that it's "some type which is an ancestor (superclass) of E"; the second (<? 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 it's compatible) The drainTo method
  • 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
