Answer
Abstraction is achieved using abstract classes and interfaces.
Abstraction in Java is the concept of hiding complex implementation details and showing only the necessary features. This is achieved through abstract classes and interfaces. Abstract classes provide a partial implementation, while interfaces define methods without implementations. For instance, an interface 'PaymentMethod' might declare 'processPayment()', and various classes like 'CreditCard' and 'PayPal' will implement it.
