java8 源码 浅析java8 Stream Classes to support functional-style operations on streams of elements, such as map-reduce transformations on collections. 1.代码 List strList = new ArrayList<>(); strList.add("1"); strList.add("2"); strList.add("3"); strList.stream().filter(Objects::nonNull).map(Integer::valueOf).forEach(System.out::println); 2.解析 以上代码一个简单的 stream 的应用, 分成 stream ->filter+ map->forEach,stream一次消费流 1.Stream ​ 最终返回的对象是 ReferencePipeline.Head 2.filter 无状态 诸如map或者filter会从输入流中获取每一个元素
