最简单的方法(simple collect -支持并行流):

public static <T> Stream<T> reverse(Stream<T> stream) {
    return stream
            .collect(Collector.of(
                    () -> new ArrayDeque<T>(),
                    ArrayDeque::addFirst,
                    (q1, q2) -> { q2.addAll(q1); return q2; })
            )
            .stream();
}

高级方式(以持续的方式支持并行流):

public static <T> Stream<T> reverse(Stream<T> stream) {
    Objects.requireNonNull(stream, "stream");

    class ReverseSpliterator implements Spliterator<T> {
        private Spliterator<T> spliterator;
        private final Deque<T> deque = new ArrayDeque<>();

        private ReverseSpliterator(Spliterator<T> spliterator) {
            this.spliterator = spliterator;
        }

        @Override
        @SuppressWarnings({"StatementWithEmptyBody"})
        public boolean tryAdvance(Consumer<? super T> action) {
            while(spliterator.tryAdvance(deque::addFirst));
            if(!deque.isEmpty()) {
                action.accept(deque.remove());
                return true;
            }
            return false;
        }

        @Override
        public Spliterator<T> trySplit() {
            // After traveling started the spliterator don't contain elements!
            Spliterator<T> prev = spliterator.trySplit();
            if(prev == null) {
                return null;
            }

            Spliterator<T> me = spliterator;
            spliterator = prev;
            return new ReverseSpliterator(me);
        }

        @Override
        public long estimateSize() {
            return spliterator.estimateSize();
        }

        @Override
        public int characteristics() {
            return spliterator.characteristics();
        }

        @Override
        public Comparator<? super T> getComparator() {
            Comparator<? super T> comparator = spliterator.getComparator();
            return (comparator != null) ? comparator.reversed() : null;
        }

        @Override
        public void forEachRemaining(Consumer<? super T> action) {
            // Ensure that tryAdvance is called at least once
            if(!deque.isEmpty() || tryAdvance(action)) {
                deque.forEach(action);
            }
        }
    }

    return StreamSupport.stream(new ReverseSpliterator(stream.spliterator()), stream.isParallel());
}

注意，您可以快速扩展到其他类型的流(IntStream，…)。

测试:

// Use parallel if you wish only
revert(Stream.of("One", "Two", "Three", "Four", "Five", "Six").parallel())
    .forEachOrdered(System.out::println);

结果:

Six
Five
Four
Three
Two
One

其他注意事项:最简单的方法是，当它与其他流操作一起使用时就不那么有用了(收集连接破坏了并行性)。前进的方式就没有这个问题，它也保持了流的初始特征，比如排序，所以，它是在反向操作之后用于其他流操作的方式。

以下是我想出的解决方案:

private static final Comparator<Integer> BY_ASCENDING_ORDER = Integer::compare;
private static final Comparator<Integer> BY_DESCENDING_ORDER = BY_ASCENDING_ORDER.reversed();

然后使用这些比较器:

IntStream.range(-range, 0).boxed().sorted(BY_DESCENDING_ORDER).forEach(// etc...

基于@stuart-marks的答案，但没有强制转换，函数返回从end开始的列表元素流:

public static <T> Stream<T> reversedStream(List<T> tList) {
    final int size = tList.size();
    return IntStream.range(0, size)
            .mapToObj(i -> tList.get(size - 1 - i));
}

// usage
reversedStream(list).forEach(System.out::println);

此方法适用于任何流，并且兼容Java 8:

Stream<Integer> myStream = Stream.of(1, 2, 3, 4, 5);
myStream.reduce(Stream.empty(),
        (Stream<Integer> a, Integer b) -> Stream.concat(Stream.of(b), a),
        (a, b) -> Stream.concat(b, a))
        .forEach(System.out::println);

这里的许多解决方案对IntStream进行排序或反转，但这不必要地需要中间存储。斯图尔特·马克斯的解决方案是可行的:

static IntStream revRange(int from, int to) {
    return IntStream.range(from, to).map(i -> to - i + from - 1);
}

它正确地处理溢出以及，通过这个测试:

@Test
public void testRevRange() {
    assertArrayEquals(revRange(0, 5).toArray(), new int[]{4, 3, 2, 1, 0});
    assertArrayEquals(revRange(-5, 0).toArray(), new int[]{-1, -2, -3, -4, -5});
    assertArrayEquals(revRange(1, 4).toArray(), new int[]{3, 2, 1});
    assertArrayEquals(revRange(0, 0).toArray(), new int[0]);
    assertArrayEquals(revRange(0, -1).toArray(), new int[0]);
    assertArrayEquals(revRange(MIN_VALUE, MIN_VALUE).toArray(), new int[0]);
    assertArrayEquals(revRange(MAX_VALUE, MAX_VALUE).toArray(), new int[0]);
    assertArrayEquals(revRange(MIN_VALUE, MIN_VALUE + 1).toArray(), new int[]{MIN_VALUE});
    assertArrayEquals(revRange(MAX_VALUE - 1, MAX_VALUE).toArray(), new int[]{MAX_VALUE - 1});
}

How about reversing the Collection backing the stream prior?

import java.util.Collections;
import java.util.List;

public void reverseTest(List<Integer> sampleCollection) {
    Collections.reverse(sampleCollection); // remember this reverses the elements in the list, so if you want the original input collection to remain untouched clone it first.

    sampleCollection.stream().forEach(item -> {
      // you op here
    });
}
