  • What is the relationship between subclass and superclass?

    Definitions: A class that is derived from another class is called a subclass (also a derived class, extended class, or child class). The class from which the subclass is derived is called a superclass (also a base class or a parent class).

  • How do you call a sub class in super class?

    A subclass can call a constructor defined by its superclass by use of the following form of super: super(parameter-list); Here, parameter-list specifies any parameters needed by the constructor in the superclass. super( ) must always be the first statement executed inside a subclass constructor.

  • What are association classes?

    In UML diagrams, an association class is a class that is part of an association relationship between two other classes. You can attach an association class to an association relationship to provide additional information about the relationship.
  • It is important to note that a subclass is not a "subset" of a superclass. In contrast, subclass is a "superset" of a superclass. It is because a subclass inherits all the variables and methods of the superclass; in addition, it extends the superclass by providing more variables and methods.
