Course Headline:

Dive into the World of Functional Programming with Java 8 Lambda Expressions! 🌐

About the Course:

Welcome to our comprehensive online course designed for intermediate Java developers who are keen to explore the powerful features introduced in Java 8. This course will serve as a guiding light through the realms of lambda expressions, functional interfaces, streams, and much more!

Why Java 8? 🤔

Java 8 brought a paradigm shift with its introduction of lambda expressions and functional programming concepts, making our code cleaner, more readable, and highly concurrent. Understanding these features is crucial for modern Java development.

Course Highlights:

• Understanding Lambda Expressions: Learn the basics of lambda expressions and how they can simplify your code.
• Functional Interfaces: Get to grips with the new functional interfaces like Consumer, Supplier, Function, Predicate, and many more.
• Streams: Discover the power of streams for processing collections in a declarative manner.
• Parallel Streams: Learn when and how to leverage parallel streams for concurrency and performance optimization.
• Optional Class: Master the usage of the Optional class for cleaner null handling.
• Default and Static Methods in Interfaces: Understand how these methods can extend your interfaces without modifying their implementation.

Sub Topics Covered:

1. Introduction to Lambda Expressions

   • What are Lambda Expressions?
   • How to implement Runnable and Comparator using Lambdas.

2. Functional Interfaces Overview

   • Introduction to Consumer, Supplier, Function, Predicate, etc.

3. Streams in Java 8

   • Understanding Streams with examples.
   • Working with map, filter, reduce, and more.

4. Effective Parallel Processing

   • When to use parallel streams.
   • Best practices for avoiding common pitfalls.

5. Handling Optional Values

   • Utilizing the Optional class effectively.
   • Avoiding null pointer exceptions.

6. Java 8 Functional Interface Methods

   • Exploring default and static methods in interfaces.
   • Real-world examples of their usage.

Course Breakdown:

1. Lambda Expressions: We'll start by understanding the syntax and capabilities of lambda expressions, and how they differ from traditional anonymous classes. You'll learn to create lambdas that can be passed as arguments to methods.

2. Functional Interfaces: Next, we'll explore the functional interfaces introduced in Java 8 and how they are used with lambdas. We'll cover the most common ones and understand their role in functional programming.

3. Streams: Dive into the streams API, which allows you to process elements of a collection in a functional style, utilizing higher-order functions like map, filter, sorted, and more. We'll also cover the Collector classes and how to collect data in various forms using them.

4. Parallel Streams: Learn the ins and outs of parallel streams, including performance considerations and when they can be advantageous. We'll also discuss the potential drawbacks and best practices for their use.

5. Optional Class: Understand how the Optional class can help you write more robust code by avoiding NullPointerExceptions. We'll see how to use methods like ifPresent, orElse, and orElseThrow.

6. Default Methods in Interfaces: Finally, we'll delve into the new features of Java 8 interfaces, particularly default and static methods, and understand how they provide a way to add new methods to an interface without breaking the implementations of that interface by existing classes.

What You Will Learn:

• How to write concise, readable code using lambda expressions.
• The power of functional interfaces and how they facilitate lambda usage.
• How to process data streams effectively for performance and clarity.
• When and how to leverage parallel streams to take advantage of multi-core processors.
• Techniques for handling optional values without the fear of null pointer exceptions.
• How to extend interfaces with default and static methods.

By the end of this course, you'll be equipped with a solid understanding of Java 8's functional programming features, enabling you to write more efficient and maintainable code. Get ready to transform your approach to Java development!
