java怎么获取list的每个元素？

Posted 2023-03-19

参考技术A

List<Integer> list = new ArrayList<Integer>();
for (int i = 0; i < list.size(); i++)
System.out.println(list.get(i))。

ist features = Arrays.asList("a", "b", "c","d");features.forEach(n -> System.out.println(n));//jdk8

ist<Integer> list = new ArrayList<Integer>();
for (int i = 0; i < list.size(); i++)
System.out.println(list.get(i));
