Lambda和Streams

是Java 8引入的两个重要特性,用于简化并发编程和集合操作。

Lambda表达式是一种匿名函数,它可以作为参数传递给方法或存储在变量中。Lambda表达式可以简化代码,使代码更加简洁和易读。Lambda表达式的语法为:(参数列表) -> 表达式或代码块。

Streams是一种用于处理集合数据的抽象概念。它提供了一种流式处理集合元素的方式,可以进行过滤、映射、排序、归约等操作。Streams可以提高代码的可读性和简洁性,并且可以利用多核处理器的优势进行并行处理。

Lambda和Streams的优势包括:

  1. 简化代码:Lambda表达式可以将复杂的代码逻辑简化为一行或几行代码,使代码更加简洁和易读。
  2. 并发编程:Lambda表达式和Streams可以方便地进行并发编程,利用多核处理器的优势提高程序的性能。
  3. 高效的集合操作:Streams提供了丰富的集合操作方法,可以方便地进行过滤、映射、排序、归约等操作,提高代码的可读性和简洁性。

Lambda和Streams的应用场景包括:

  1. 集合操作:Streams可以方便地对集合进行各种操作,如过滤、映射、排序等。
  2. 并发编程:Lambda表达式和Streams可以方便地进行并发编程,提高程序的性能。
  3. 函数式编程:Lambda表达式是函数式编程的重要特性,可以简化函数式编程的代码。

    java.util.stream public interface Collector<T, A, R> A mutable reduction operation that accumulates input elements into a mutable result container, optionally transforming the accumulated result into a final representation after all input elements have been processed. Reduction operations can be performed either sequentially or in parallel. Examples of mutable reduction operations include: accumulating elements into a Collection; concatenating strings using a StringBuilder; computing summary information about elements such as sum, min, max, or average; computing "pivot table" summaries such as "maximum valued transaction by seller", etc. The class Collectors provides implementations of many common mutable reductions. A Collector is specified by four functions that work together to accumulate entries into a mutable result container, and optionally perform a final transform on the result. They are: creation of a new result container (supplier()) incorporating a new data element into a result container (accumulator()) combining two result containers into one (combiner()) performing an optional final transform on the container (finisher()) Collectors also have a set of characteristics, such as Collector.Characteristics.CONCURRENT, that provide hints that can be used by a reduction implementation to provide better performance. A sequential implementation of a reduction using a collector would create a single result container using the supplier function, and invoke the accumulator function once for each input element. A parallel implementation would partition the input, create a result container for each partition, accumulate the contents of each partition into a subresult for that partition, and then use the combiner function to merge the subresults into a combined result. To ensure that sequential and parallel executions produce equivalent results, the collector functions must satisfy an identity and an associativity constraints. The identity constraint says that for any partially accumulated result, combi
