Originally published by Javin Paul on December 2nd 2018 A curated list of some of the best resources to learn Java 8 Programming like lambda expression, method references etc. While the term “lambda expression” may sound abstract and academic, Java 8 Lambdas can have a big impact on how you program every day. Java 8 has not only introduced Lambda expressions but also Stream API, Functional interfaces, new Date and Time API and default methods, which has completely changed the way you write your Java code. As a professional Java developer, you will have to learn Java 8 one day, and it’s better to do sooner than later. Even if you are not using many of the Java 8 features, one thing is sure that It’s definitely changed change how you use Collection framework classes e.g. ArrayList or HashMap in your Java program, especially for high-performance applications. Not surprisingly, I have also learned Java 8 new features and I am grateful to all these peoples, who have shared wonderful tutorials on lambdas and other Java 8 concepts. These are the people who have mostly downloaded nightly builds, work through specification and the initial draft to create, easy to understand Java 8 tutorials and examples. Since I am personally following them, it makes a lot of sense for me to share all these resources with you guys, my readers. Earlier, when I shared some differences between Java and Scala, I had mentioned about some cool features of Scala, which makes code concise, clear and more readable but Java 8 is brought parity on that as well. So stay tuned and follow these Java 8 Lambdas, Stream API, and functional interfaces tutorial to get a feel of, what is going to be the biggest change in Java programming language since it’s the first launch; probably even bigger than Generics from Java 1.5. What is Lambda expression in Java In simplest terms, a lambda expression is a function — a bit of code — that you can pass to another method as an argument. Thus, you can cope with changing requirements by using a behavior, represented by a lambda, as a parameter. If you have done some JavaScript programming then you know that you can pass anonymous function to any function, till Java 1.7 it was not possible in Java, you can only pass primitive or object to your methods. One part of Java API, which is going to substantial change is the famous and probably most used Java Collection Framework, which is being reworked to use Stream API. Java 8’s functional programming features, like lambdas and the new Stream API, will provide a cleaner way to iterate through collections. They are also going to help you write concise, maintainable code that scales easily and performs well on multicore architectures. If you are interested to learn more about lambda expression then the What’s New in Java 8: Lambdas is a great course which provides an in-depth look at the new features of Java 8. Some of the best Java 8 Tutorials As I said, I have started learning Java 8 new features to get myself ready to adopt Java 8 as soon as possible. I have a gut feeling that industry will probably do the same and once Java 8 will be formally released,  » Read More
