Can we call a subclass constructor from a superclass constructor? Please explain.
No, we cannot directly call a subclass constructor from a superclass constructor. In Java and similar object-oriented languages, the superclass constructor is always called first when creating an instance of a subclass. This ensures that the state of the superclass is properly initialized before the subclass begins its own initialization. However, it’s not possible to explicitly invoke a subclass constructor from within a superclass constructor because at the time the superclass constructor is running, the subclass part of the object has not yet been created.
