This property makes it possible to define higher-order functions in functional programming.Higher-order functions are capable of receiving functions as arguments and returning a function as a result.This further enables several techniques in functional programming such as function composition and currying....
接下来就要引入另一个关键的内容,即 java.util.function 包,官方对它的定义是:“Functional interfaces provide target types for lambda expressions and method references. ” 即为定义函数对象提供的类,也就是如何存储一个函数对象。也就是它专门用来解决上面提出的这个问题: 回到刚刚的这个 Lambda 表达式:x -> ...

Functional Java is an open source library facilitating functional programming in Java. The library implements numerous basic and advanced programming abstractions that assist composition oriented development. Functional Java also serves as a platform for learning functional programming concepts by introducing th...
函数式编程（Functional Programming）是一种编程范式，它将计算过程视为函数的求值，主张使用纯函数和不可变数据。在 Java 8 中，引入了函数式接口（Functional Interface）的概念，使得函数式编程在 Java 中也能得以实现。函数式接口就是一个具有一个方法的接口。这种方法被称为“函数描述符”。例如，java.util....

在讨论函数式编程(Functional Programming)的具体内容之前,我们首先看一下函数式编程的含义。在维基百科上,函数式编程的定义如下:"函数式编程是一种编程范式。它把计算当成是数学函数的求值,从而避免改变状态和使用可变数据。它是一种声明式的编程范式,通过表达式和声明而不是语句来编程。" (见 Functional Programming)...

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...
