Java 8 Stream的filter方法如何使用? Java 8 Stream的map方法能进行哪些操作? 1、什么是流? Stream 作为 Java 8 的一大亮点,它与 java.io 包里的 InputStream 和 OutputStream 是完全不相关的东西。 Java 8 中的 Stream 是对集合(Collection)对象功能的增强,它专注于对集合对象进行各种非常便利、高效的聚合操作...
filter:过滤流中的某些元素 limit(n):获取n个元素 skip(n):跳过n元素,配合limit(n)可实现分页 distinct:通过流中元素的 hashCode() 和equals() 去除重复元素 Stream<Integer> stream = Stream.of(6, 4, 6, 7, 3, 9, 8, 10, 12, 14, 14); Stream<Integer> newStream = stream.filter(s -> s ...
The above behavior is valid for allsequential and parallel streams.The behavior offindFirst()does not change by theparallelismof the Stream. 2. StreamfindFirst()Example In the given example, we are getting the first element from theStreamof strings. As soon as, we get the first element, the...
