java怎么获取list的每个元素

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

for循环
List list = new ArrayList();
for (int i = 0; i < list.size(); i++) {
System.out.println(list.get(i));
}

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

for(int i = 0;ilist.get(i);
}

for循环就可以
