functional interface java 8

"Editor's note" the author of this article is dedicated to natural language processing for many years Pierre-yves Saumont,pierre-yves has more than 30 lectures on Java software development books, since 2008 began to work in Alcatel-lucent company, as a software development engineer.This paper mainly introduces the closure and local application function in Java 8,

"Consumer" function to the "ForEach" operation, a high-order "inner Loop" The operation passes each element in the collection one by one to consumer's "accept" method and executes it.As mentioned above, for such a higher order function, the practice of a functional language is to receive a function parameter instead of an object. Although the transfer function reference itself is traditionally beyond the scope of

powerful and has good reusability, each function is like a Lego block, and these bricks can assemble endless combinations.Designing higher-order functionsHigher-order functions are a significant feature introduced in Java 8, where we can only pass in objects or values as parameters to methods. The introduction of higher-order functions allows us to pass functions as parameters. This can undoubtedly greatly

For a long time, Java was a language of redundancy and lack of functional programming capability, and this style of programming was introduced with the popular java8 of functional programming. Befo
