Answer
An abstract class can provide partial implementation of methods.
Partial implementation means an abstract class in Java can have some methods fully implemented while others remain abstract. This allows subclasses to inherit common behavior, while still enforcing specific behaviors through abstract methods. For instance, an abstract class 'Payment' might fully implement a 'calculateDiscount' method but leave 'processPayment' as abstract, requiring subclasses like 'CreditCardPayment' or 'PaypalPayment' to provide specific implementations.
