Klassenverweise

Klassenverweise, also class references, are a feature in object-oriented programming that allow a class to refer to itself within its own methods or properties. This is particularly useful when a class needs to create an instance of itself, or when it needs to access its own static members. In languages like Java, C#, and Python, the keyword "this" or "self" is used to refer to the current instance of the class, while "class" or the class name itself is used for static members.

Class references can also be used in inheritance hierarchies. For example, a subclass can use a superclass reference to call a method defined in the superclass. This is often done using the "super" keyword in languages like Java and C#.

In some languages, class references can be used to create generic classes or methods. For example, in Java, the "Class" class can be used to create a generic method that can operate on any type of object.

Overall, class references are a powerful feature in object-oriented programming that allow for greater flexibility and reusability in code. However, they should be used judiciously, as overuse can lead to code that is difficult to understand and maintain.
