  • java - What is a Subclass - Stack Overflow
    A subclass is a class that describes the members of a particular subset of the original set They share many of characteristics of the main class, but may have properties or methods that are unique to members of the subclass You declare that one class is subclass of another via the "extends" keyword in Java public class B extends A {
  • CSS Classes SubClasses - Stack Overflow
    Following on from kR105's reply above: My problem was similar to that of the OP (Original Poster), only occurred outside a table, so the subclasses were not called from within the scope of the parent class (the table), but outside of it, so I had to ADD selectors, as kR105 mentioned
  • Python: How do I make a subclass from a superclass?
    This is a subclass of list which, when initialized, immediately sorts itself in the direction specified by the reverse keyword argument, as the following tests illustrate:
  • Explicit casting from super-class to sub-class - Stack Overflow
    As it was said before, you can't cast from superclass to subclass unless your object was instantiated from the subclass in the first place However, there are workarounds All you need is a set of constructors and a convenience method that will either cast your object to Dog, or return a new Dog object with the same Animal properties
  • How do I call a method of a subclass from a superclass method?
    And this subclass in other file: from classfile import MyClass class MySubclass(MyClass): def firstFunc(self, a, b): c = a + b d = self secondFunc(self, c) return d def secondFunc(self, c): d = c 2 return d This is a silly example, but represents exactly what I'm trying to do
  • Python 3. 7: check if type annotation is subclass of generic
    I'm trying to find a reliable cross-version (3 5+) way of checking whether a type annotation is a "subclass" of a given generic type (i e get the generic type out of the type annotation object) On Python 3 5 3 6, it works a breeze, as you would expect:
  • oop - Subclass `pathlib. Path` fails - Stack Overflow
    Rather than directly returning an instance of Path from its __new__(), it returns an instance of a subclass, but only if it's been invoked directly as Path() (and not as a subclass) Otherwise, it expects to have been invoked via either WindowsPath() or PosixPath() , which both provide a _flavour class attribute via multiple inheritance
  • Java: Subclassing a genericised class - Stack Overflow
    Okay, here is a stab at explanation Since SomeTable is generic, he could declare another subclass SubTable extends SomeTable<SpecialEntry> In this case, the hard-coded SomeTableEntry would not work anymore, because the expected erased type would now be SpecialEntry
  • Whats the difference between subClass sc = new subClass() and . . .
    In addition to the above answers, because the constructed object is really an object of type SubClass you can cast it to SubClass and call the methods: SuperClass superClass = new SubClass(); superClass method1(); ((SubClass)superClass) method2();
