Question

java怎么获取list的每个元素？

Answer 1

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

2. ist features = Arrays.asList("a", "b", "c","d");
3. 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));
