forEachOrdered在并行情况下,按顺序执行。 代码: //如果不是parallel()并行处理, 这2个方法没区别 Stream.of("AAA","BBB","CCC").forEach(s->System.out.println("Output:"+s)); Stream.of("AAA","BBB","CCC").forEachOrdered(s->System.out.println("Output:"+s)); //parallel()并行处理的情况...
第三步:使用forEachOrdered遍历数据 这里,使用forEachOrdered来遍历Stream中的每个元素,并保证它们的顺序。此时,如果需要并行处理,可以使用parallelStream(),但forEachOrdered仍能保证输出顺序。 names.parallelStream()// 创建并行Stream.forEachOrdered(name->{// 打印每一个名字,顺序保持System.out.println(name);});...
2. Stream forEach() vs forEachOrdered() The behavior offorEach()operation is explicitly non-deterministic. For parallel streams,forEach()operation does not guarantee to respect the encounter order of the Stream. While theforEachOrdered()operationrespects theencounter order of the stream if the s...
...> forEach(System.out::println); 输出是 5 和 6,正如预期的那样,因为它们大于 5,小于 7。 流终端操作 终端操作是遍历中间操作管道并进行适当调用的值或副作用操作。它们可以处理返回的值(forEach(...)、forEachOrdered(...)),也可以返回以下任意值: 迭代器(例如iterator()和spliterator()方法) 集合(...

void forEachOrdered(Consumer<? superT> action) Performs an action for each element of this stream, in the encounter order of the stream if the stream has a defined encounter order. This is aterminal operation. This operation processes the elements one at a time, in encounter order if one ...
