OOP Polymorphism

Master polymorphism to create flexible, extensible object-oriented systems. This skill focuses on understanding and applying polymorphic behavior through interfaces, abstract classes, and runtime type substitution.

Understanding Polymorphism

Polymorphism allows objects of different types to be treated uniformly through a common interface. It enables writing code that works with abstractions rather than concrete implementations.

Interface-Based Polymorphism in Java

// Common interface for all payment methods
public interface PaymentMethod {
    PaymentResult process(BigDecimal amount);
    boolean isValid();
    String getDisplayName();
}

// Concrete implementations
