Java 8 New Features In‑Depth + Practice Tests

This course is designed to help Java developers gain a clear and practical understanding of Java 8 new features, focusing on the concepts that fundamentally changed the way Java applications are written. It is ideal for developers who already have basic Java knowledge and want to upgrade their skills to modern Java programming standards.

The course begins with Java 8 interface enhancements, explaining default and static methods and how they help in evolving interfaces without breaking existing implementations. You will understand why these changes were introduced and how they are used in real‑world Java applications.

A major part of the course focuses on functional programming concepts in Java, introducing a new programming style that emphasizes immutability, declarative logic, and cleaner code. You will learn how Java adopted functional programming principles while remaining backward compatible.

The course then dives into functional interfaces, explaining their purpose, rules, and usage. You will understand how functional interfaces act as the foundation for lambda expressions and the Java 8 Streams API.

You will also learn Java 8 Streams, one of the most powerful features introduced in Java 8. Streams allow you to process collections efficiently using a functional approach, enabling cleaner, more readable, and more maintainable code.

A bonus lecture is included to guide you on what to learn next after mastering Java 8 features. Practice tests are provided to reinforce learning and validate your understanding of Java 8 concepts.
