In this tutorial, we’ll understand the functional programming paradigm’s core principles and how to practice them in the Java programming language. We’ll also cover some of the advanced functional programming
In this tutorial, we’ll provide a quick overview of theFunctional Javalibrary along with a few examples. 2. The Functional Java Library The Functional Java library is an open source library meant to facilitate functional programming in Java. The library provides lots of basic and advanced progra...
The conciseness achieved by using lambda expressions so far is nice, but code duplication might sneak in quickly if you’re not careful. I’ll address this concern in the second part of this article, “Functional programming in Java, Part 2: Lambda reuse, lexical scoping and closur...
In this case, you need a functional interface that contains an abstract method that returns a value. The Function<T,R> interface contains the method R apply(T t). The following method retrieves the data specified by the parameter mapper, and then performs an action on it specified by the...

函数式编程(Functional Programming)是一种编程范式。它已经有近60年的历史,因其更适合做并行计算,近年来开始受到大数据开发者的广泛关注。Python、JavaScript等当红语言对函数式编程支持都不错,Scala更是以函数式编程的优势在大数据领域攻城略地,即使是老牌的Java为了适应函数式编程,也加大对函数式编程的支持。未来的程序...
In many functional programming languages a construct like this can be invoked as if this was just one simple function by doing: 1 1 sum105//yields 15 But the truth is that this is just syntactic sugar to do: 1 1 sum(10)(5)//yields 15 ...

Modern Java features, such as lambda expressions, method references, and functional programming, can be leveraged to simplify the implementation of design patterns. For example, the Strategy pattern can be implemented more concisely using lambda expressions, making the code more expressive and easier to...
