java迭代器循环写法

Java迭代器循环写法有两种，分别是for-each循环和while循环。具体如下：

1. for-each循环

List<String> list = new ArrayList<>();
list.add("a");
list.add("b");
list.add("c");
for (String str : list) {
    System.out.println(str);
}

2. while循环

List<String> list = new ArrayList<>();
list.add("a");
list.add("b");
list.add("c");
Iterator<String> iterator = list.iterator();
while (iterator.hasNext()) {
    String str = iterator.next();
    System.out.println(str);
}
