In this first article in the new Java 8 idioms series, I explain the difference and overlap between imperative, declarative, and functional programming styles. Then, I show you how to use declarative thinking to gradually integrate functional techniques into your Java programs.
In this Java 8 course for experienced programmers, Martin Kalin introduces constructs such as lambda expressions, method references, constructor references, and the Java Streams API. This is a code-driven course for the Java programmer who wants real hands-on experience working with functional programming.
Java 8 is not a functional programming language, but as I said before it is trying its best to be. Java functions do not meet the requirements of a pure function. Java 8 is somewhere between object oriented programming and functional programming.
Functional programming is a paradigm that allows programming using expressions i.e. declaring functions, passing functions as arguments and using functions as statements (rightly called expressions in Java8). If you want to learn more about why it is called Lambda expressions, you could try to understand what Lambda Calculus is.

In this Java 8 course for experienced programmers, Martin Kalin introduces constructs such as lambda expressions, method references, constructor references, and the Java Streams API. This is a code-driven course for the Java programmer who wants real hands-on experience working with functional
The single most important change in Java 8 enables faster, clearer coding and opens the door to functional programming. Here’s how it works. Here’s how it works. Java was designed in the 1990s as an object-oriented programming language, when object-oriented programming was the principal paradigm for software development.

In practice, Java programmers have always mixed object-oriented and functional-style programming styles. – Object-oriented programming style: everything is an object and programs operate by updating fields and calling methods that update their associated object.
The recording of our March 12th webinar featuring Venkat Subramaniam, Functional Programming with Java 8, is now available on JetBrains YouTube Channel. In this presentation, we discuss how Java 8 now facilitates a functional style of programming and why we should care about it.

interfaces packaged in java.util.function. A functional interface is an interface that defines one and only one abstract method. Functional interfaces provide support for lambda expressions and method references. JDK 8 also puts JavaFX front and center. This powerful GUI framework is something that no Java programmer should ignore. With the release of JDK 8, the world of Java programming is
Before the launch of Java 8, Java was lacking functional constructs. Functional Programming in Java helps Java developers to incorporate the most powerful benefits of functional programming into new and existing Java code to make applications optimized, maintainable, and easier to understand.
My personal experience has been that Java 8 lambda plus deep class hierarchies can lead to some truly impenetrable code (to read that is). In practice mixing oop and the meager functional tools (as you note) in Java can be really, really bad, and makes me weep at the future of Java development.
27/03/2014 · With the release of Java 8, the biggest change is going to be in the programmers mind. In addition to the new syntax for lambda expressions and method references, a significant paradigm shift


Functional Programming in Java 8 is a three-day course aimed at experienced developers with little or no experience in Functional Programming. The goal is …
For years Java has received the label of not being an appropriate programming language for functional programming techniques, because functions were not the first class citizens in the language. Indeed, there wasn’t a neat and accepted way to refer to a code block by a name and pass it around. Lambdas in JDK 8 changed that. Now we can use
It’s been four years since functional programming became feasible in Java. The means we have had four years to play with Java 8. And we’ve played… and played.
Our Java team has recently prepared a hands-on workshop on functional programming in Java 8. The participants solved our coding tasks, trying out the Java 8’s features in separation, and now it’s time we show off how we employ the full power of Java 8 in our real-life projects.

An Introduction to Functional Programming in Java 8: Part 0 – Motivation As I’ve seen in my previous post , the interest in functional programming is high. This is the reason I want to write an introduction about it.
This is a very rapid course on Java 8 functional programming. Functional programming has been the most important of all Java 8 new features. Using Java 8 functional programming, we can now code many things much faster than before, in a concise, fluent and readable manner.
