stream的内容比较多,先简单看一下它的说明: A sequence of elements supporting sequential and parallel aggregate*operations. The following example illustrates an aggregate operation using*{@link Stream} and {@link IntStream}:* * <pre>{@code*intsum =widgets.stream()* .filter(w -> w.getColor()...
Example #2 - Java 8 streams The following code: public static List<String> testMapAndCollectBounds(List<String> input) { return input.stream() .map(e -> e.toUpperCase()) .collect(Collectors.toList()); } fails with a compilation error: ...
用传统的迭代处理也不是很难,但代码就显得冗余了,跟Stream相比高下立判。 1 Stream概述 Java 8 是一个非常成功的版本,这个版本新增的Stream,配合同版本出现的 Lambda ,给我们操作集合(Collection)提供了极大的便利。 那么什么是Stream? Stream将要处理的元素集合看作一种流,在流的过程中,借助Stream API对流中的...
