Hey folks! It's 2020 now and Java 8 was introduced back in 2014. Yet, I still see many developers struggling with it every day. So, I'm here to help you out. I've written a series of blog posts to guide you in understanding Java 8, transitioning from Java 7, or just refreshing your concepts. I suggest you read each post in order:
-
Lambda expressions in Java 8: One of the coolest new features in Java 8, which allows you to do a lot with very little code. It also enables functional programming paradigm. You can even copy-paste the code snippets from the post to your editor, and they will compile perfectly fine.
-
Asynchronous Programming in Java 8: If you're working with reactive programming, understanding the CompletionStage and CompletableFuture API is essential. This post covers how to use the CompletableFuture API, so you can skip it if you don't need to process data asynchronously.
-
Method References in Java 8: Method references can help you write clean code, and the concept is pretty straightforward. However, it can be tricky to know when to use it. It's a super cool feature that can save you a lot of time and make your code look more concise and easier to read and maintain.
-
Aggregate Operations in Java 8: Aggregate operations are also very cool. I first used them in Python, and when I tried them in Java 8, they were pretty intuitive. If you're working with big data, learning about aggregate operations is a must. But even if you're not, it's a good idea to learn and incorporate them into your development.
I hope these posts help you out in your Java 8 journey. Don't forget to try out the code snippets and let me know if you have any questions or suggestions. Happy coding!
