apply(T t):这是Function接口的主要方法,它接收一个参数并返回一个结果。同时它也是唯一的抽象的方法,剩下的都是有默认实现的(Java 8 中接口的抽象方法支持默认实现)。 andThen(Function after):作用是将两个Function组合。首先执行当前函数,再执行andThen函数,并将当前函数的结果作为参数传递给andThen函数。 compo...

Packagejava.util.function Interface IntFunction<R> Type Parameters: R- the type of the result of the function Functional Interface: This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference. ...
在python中,通过使用=运算符将对象(如返回值)绑定到名称来存储变量。你可以这样做: s = stdev()print(s)...v = variance()print(v)...# Use v + s in an expression instead of variance + stdev Java的“Function”“and then()”“apply()”是否有最多7个步骤的限制?
1 前言 这几个接口都处在java.util.function包下，Consumer（消费型），Supplier（供给型）、Predicate（...
