Java 8中的常用函数式接口

函数式接口	函数描述符	原始类型特化
`Predicate<T>`	`T->boolean`	`IntPredicate,LongPredicate, DoublePredicate`
`Consumer<T>`	`T->void`	`IntConsumer,LongConsumer, DoubleConsumer`
`Function<T,R>`	`T->R`	`IntFunction<R>, IntToDoubleFunction,` `IntToLongFunction, LongFunction<R>,` `LongToDoubleFunction, LongToIntFunction,` `DoubleFunction<R>, ToIntFunction<T>,` `ToDoubleFunction<T>, ToLongFunction<T>`
`Supplier<T>`	`()->T`	`BooleanSupplier,IntSupplier, LongSupplier, DoubleSupplier`
`UnaryOperator<T>`	`T->T`	`IntUnaryOperator, LongUnaryOperator, DoubleUnaryOperator`
`BinaryOperator<T>`	`(T,T)->T`	`IntBinaryOperator, LongBinaryOperator, DoubleBinaryOperator`
`BiPredicate<L,R>`	`(L,R)->boolean`
`BiConsumer<T,U>`	`(T,U)->void`	`ObjIntConsumer<T>, ObjLongConsumer<T>, ObjDoubleConsumer<T>`
`BiFunction<T,U,R>`	`(T,U)->R`	`ToIntBiFunction<T,U>, ToLongBiFunction<T,U>, ToDoubleBiFunction<T,U>`

使用案例	Lambda 的例子	对应的函数式接口
布尔表达式	`(List<String> list) -> list.isEmpty()`	`Predicate<List<String>>`
创建对象	`() -> new Project()`	`Supplier<Project>`
消费一个对象	`(Project p) -> System.out.println(p.getStars())`	`Consumer<Project>`
从一个对象中选择/提取	`(int a, int b) -> a * b`	`IntBinaryOperator`
比较两个对象	`(Project p1, Project p2) -> p1.getStars().compareTo(p2.getStars())`	`Comparator<Project> 或 BiFunction<Project,` `Project, Integer> 或 ToIntBiFunction<Project, Project>`
