![]() ![]() ![]() More and more I look at them, it makes me write more clean code in Java. I am personally very excited about Java 8, particularly lambda expression and stream API. In this post, I am going to share with you the 10 most useful ways to use lambda expressions in your code, these examples are simple, short, and clear, which will help you to pick lambda expressions quickly.Īnd, If you are not familiar with Lambda Expression and Stream in Java then I suggest you check to Learn Java Functional Programming with Lambdas & Streams by Rang Rao Karnam on Udemy, which explains both Functional Programming and Java Stream fundamentals in good detail. I have been writing about Java 8 and have shared some useful resources to master Java 8 in the past. Since the biggest impact of the Java 8 release will be on the Java Collections framework its best to try examples of Stream API and lambda expression to extract, filter, and sort data from Lists and Collections. lambda expressions, functional interface, stream API, default methods, and new Date and Time API.Īs a developer, I have found that the best way to learn and master lambda expression is to try it out, do as many examples of lambda expressions as possible. Though the industry will take its time to adopt Java 8, I don't think any serious Java developer can overlook key features of the Java 8 release e.g. This mix of a bit of functional and full of object-oriented capability is a very exciting development in the Java ecosystem, which will further enable the development and growth of parallel third-party libraries to take advantage of multi-processor CPUs. Lambda expression replaces anonymous classes and removes all boilerplate, enabling you to write code in a functional style, which is sometimes more readable and expression. Prior to Java 8, if you want to pass behavior to a method, then your only option was the Anonymous class, which will take 6 lines of code, and the most important line, which defines the behavior is lost in between. One feature, which is synonymous with this release is lambda expressions, which will provide the ability to pass behaviors to methods. Java 8 release is just a couple of weeks away, scheduled on 18th March 2014, and there is a lot of buzz and excitement about this path-breaking release in the Java community. ![]()
