Answer
To call a superclass constructor. Frame the concept in practical terms so you can explain it during interview discussion.
The `super()` keyword in a constructor invokes a superclass's constructor, ensuring the parent class is properly initialized. In an e-commerce system, a `PremiumProduct` might extend `Product`; using `super(name, price)` ensures basic product details are set before adding premium features.
