Java Streams Tutorial | 2020

Java Streams allows you work with Collections/Lists like never before. In the good old days we use to define every single step (code) what we wanted to accomplish, we used to write a lot of code for something very small (The Imperative approach).

What Java Streams makes it easy to work with Collections and it gives you as a developer an API where you can ask what you want instead of defining the full implementation for the thing you want. (Declarative Programming)

If you not using Java Streams 😱 then you should take a moment and watch this video to learn more about it.

Here are some resources

PS:

Happy coding 👊🏾

I just met your youtube channel while searching for something regarding spring security but after that, I watched some of your other videos as well. They are definitely awesome. Thanks for your work.

I'm glad your tutorials improved over the years. At least for the Spring Boot tutorial. Because this was rough.

Extremely helpful. Stream APIs are so powerful, thank you for breaking this down!

Nice explanation. But there's nothing wrong with using if ( multiple conditions ) it's actually faster in most cases
