几种遍历 List 的方法

遍历 List 的方法：

1. for

2. advanced for

3. Iterator

4. while

5. ListIterator

List<E> list

1. for

for (int i = 0; i < list.size(); i++) {

E element = list.get(i);

}

2. advanced for

for (E element : list) {

}

3. Iterator

for (Iterator<E> iter = list.iterator(); iter.hasNext(); ) {

E element = iter.next();

}

4. while

while (i < list.size()) {

E element = list.get(i);

i++;

}

5. ListIterator

for (ListIterator<E> iterator = list.listIterator(); iterator.hasNext(); ) {

E element = iterator.next();

}
