Constructors

Instances of a class without an explicitly defined constructor are instantiated using a default no-argument constructor provided by the compiler, initializing strings to null and integers to zero. In the case of class `SpecialPerson`, invoking the print method will output the value of `fullName`, which is assigned based on the name at the time the object is created. Additionally, a class cannot have a static constructor to initialize static fields, and child classes must explicitly call the parent class constructor if it requires parameters.
