![]() They are also going to help you write concise, maintainable code that scales easily and performs well on multicore architectures. Java 8's functional programming features, like lambdas and the new Stream API, will provide a cleaner way to iterate through collections. 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. 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. Thus, you can cope with changing requirements by using behavior, represented by a lambda, as a parameter. In simplest terms, a lambda expression is a function-a bit of code-that you can pass to another method as an argument. So stay tuned and follow these Java 8 Lambdas, Stream API, and functional interfaces tutorials 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. Since I am personally following them, it makes a lot of sense for me to share all these resources with you guys, my readers.Įarlier, when I shared some differences between Java and Scala, I had mentioned some cool features of Scala, which makes code concise, clear, and more readable but Java 8 is brought parity on that as well. These are the people who have mostly downloaded nightly builds, work through specifications, and the initial draft to create, easy-to-understand Java 8 tutorials and examples. 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. As a professional Java developer, you will have to learn Java 8 one day, and it's better to do it sooner than later.Įven 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 like ArrayList or HashMap in your Java program, especially for high-performance applications. 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. While the term "lambda expression" may sound abstract and academic, Java 8 Lambdas can have a big impact on how you program every day. ![]() ![]() Many developers, programmers, and bloggers have already shared lots of really good tutorials to learn lambda expressions, probably the biggest thing in Java world after Generic was introduced in Java 5. It's been quite some time since Java 8 was released but the Java community is still buzzing with functional programming and lambda expression. ![]()
