Answer
An abstract class cannot be instantiated. Frame the concept in practical terms so you can explain it during interview discussion.
An abstract class in Java is designed to serve as a base for other classes. It may contain abstract methods that must be implemented by subclasses. For example, if you have an abstract class 'Product' with an abstract method 'calculatePrice()', any subclass like 'ElectronicProduct' must implement 'calculatePrice()'. This ensures subclasses provide specific implementations for abstract methods while sharing common code.
