List数组的三种遍历方式

public static void main(String[] args) {
List<String> list = new ArrayList<String>();
for (int i = 0; i < 10; i++) {
list.add("a"+i);
}
//1.采用for循环遍历
for (int i = 0; i < list.size(); i++) {
System.out.println(list.get(i));
}
//2.采用forEach循环遍历
for (String string : list) {
System.out.println(string);
}
//3.采用List数组的iterator方法
Iterator<String> iterator = list.iterator();
while (iterator.hasNext()) {
System.out.println(iterator.next());
}
}
