Description

This course takes you through the latest features of Java 8 step by step. You'll get to grips with using lambdas, interfaces, streams, pipelines, methods, and optional application programming interfaces (APIs) and be ready to apply your skills to write efficient Java programs.

Whether you want to learn the fundamentals of the Java 8 programming platform or work on a project based on Java 8, this course will help you to understand its features and be able to apply your skills in real-world Java projects.
The course starts by highlighting the key differences between object-oriented programming and functional programming styles and covers the latest features of Java. Next, you will understand the role of lambda expressions and functional interfaces and learn how to use them effectively in Java programs. As you advance, you'll become familiar with different types of method references and learn techniques to apply them. You'll also get an overview of pipelines, streams, and common operations and understand the power of optional APIs to prevent null values. With the help of coding demos, you'll learn how to consolidate all that you have learned.
By the end of this course, you'll have gained the fundamental knowledge of Java 8 needed to develop and run error-free Java programs.
