stream取前几条

stream可以使用limit方法来取得前几条元素。limit方法返回一个新的流，包含了前n个元素，其中n是小于或等于给定的最大大小的值。例如，如果我们有一个数字流，可以使用limit方法来取得前几个元素。比如，对于数字流Stream.of(11, 12, 13, 14, 15)，我们可以调用limit(3)来取得前三个元素。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

java 8 list 取前五条

Java 8中，可以使用stream()和limit()方法来获取List中的前几条数据。具体实现如下：
List<KPoit> list = imWrsyQbService.selectJcdwDqWater(sjDto);
List<KPoit> resList = list.stream().limit(5).collect(Collectors.toList());
其中，limit(5)表示只取前5条数据，collect(Collectors.toList())表示将结果转换为List类型并返回。
