Given a superclass super1 and a subclass sub1, in which sequence are the constructors executed when creating an instance of sub1?

When creating an instance of a subclass in object-oriented programming, the execution sequence of constructors is critical for proper initialization. In this case, the correct sequence when creating an instance of the subclass sub1, which extends the superclass super1, starts with the class constructor of super1, followed by the instance constructor of sub1, the instance constructor of super1, and finally the class constructor of sub1.

The rationale behind this order lies in how object-oriented principles enforce inheritance workflows. Initially, the class constructor of the superclass is executed, as it establishes the static properties inherited by the subclass. Following this, the instance constructor of the subclass is called to set up any instance-specific properties defined in sub1. Next, the instance constructor of the superclass is executed to finalize the initialization of the superclass portion of the child instance. Lastly, the class constructor of the subclass is executed, completing the process by letting the subclass configure its own static aspects.

This approach ensures that when an instance of the subclass is created, it is fully compliant with the defined behavior of both the subclass and the superclass, allowing for a clear and organized way to initialize properties and methods. The sequence maintains clarity in terms of what gets initialized when, ensuring
