Example 1: Traversing the elements of a Stream and printing them In this Java example, we are iterating over aStreamof Integers and printing all the integers to the standard output. Stream forEach() Example List<Integer>list=Arrays.asList(2,4,6,8,10);Consumer<Integer>action=System.out::...
在上面的代码中,我们使用foreach循环遍历了一个整数列表,并输出每个元素的值。 for-in for-in也是一种for循环语句,用于遍历集合或数组中的元素。它的语法和foreach略有不同,以下是一个for-in的示例: List<Integer>numbers=Arrays.asList(1,2,3,4,5);for(inti=0;i<numbers.size();i++){System.out.prin...

退出stream forEach in Java 在Java中,forEach方法是用于遍历Stream中的元素的一种便捷方式。然而,有时我们希望在遍历过程中提前退出,而不是遍历完整个Stream。本文将介绍如何在Java中退出forEach方法的遍历操作。 什么是Stream forEach 在Java 8中,引入了Stream API,它提供了一种新的处理集合的方式。Stream是一种...
