A subclass invokes its base class constructor at the point of instantiation. That is; you cannot instantiate a subclass object without first constructing its base class, which is done automatically.

Class B is said to be a "subclass" of class A.

Specialization Hierarchy - has the constraint that every subclass participates asa subclass in only one class/subclass relationship, i.e. that each subclass hasonly one parent. This results in a tree structure.Specialization Lattice - has the constraint that a subclass can be a subclass of morethan one class/subclass relationship.
The base class constructor is invoked first when a subclass is instantiated, because the base class must be viable and consistent before the subclass constructor is fired.

Class B is said to be a "subclass" of class A.
A subclass is a specialized version of a class that inherits attributes and methods from its parent class. In data modeling, a subclass is useful for representing entities that have additional attributes or behaviors that are specific to a subset of instances of the parent class. Subclasses help organize data more efficiently and allow for more specific modeling of a system.
It depends what the class is.
