Java Interface (Duplicate Default Methods): Best Practices and Solutions | Java Tutorial

In this Java tutorial, we tackle the scenario of duplicate default methods in interfaces, providing a comprehensive explanation and practical solutions to handle such situations effectively.

Description:
When working with Java interfaces, you may encounter scenarios where multiple interfaces contain default methods with the same signature. This leads to conflicts and compilation errors. In this tutorial, we address this issue and explore various strategies to resolve duplicate default methods in interfaces.

We start by explaining the concept of default methods in interfaces and why conflicts arise when duplicates occur. Then, we delve into different approaches to handle duplicate default methods, including:

1. Renaming conflicting default methods to ensure uniqueness.
2. Overriding default methods in implementing classes to provide custom implementations.
3. Using the super keyword to call specific default method implementations.
4. Using interface inheritance to inherit default method implementations from other interfaces.
5. Prioritizing interfaces with default methods using interface hierarchy.

Throughout the tutorial, we provide code examples and step-by-step explanations to illustrate each approach. By the end of the tutorial, you'll have a clear understanding of how to deal with duplicate default methods in Java interfaces.
