一、使用Collections.reverse()方法反转
public void reverseList1(List<String> list) {
Collections.reverse(list);
}
二、自定义实现
public void reverseList2(List<String> list) {
List<String> tmpList = new ArrayList<>();
for (int i = list.size() - 1; i >= 0; i--) {
tmpList.add(list.get(i));
}
list.clear();
list.addAll(tmpList);
}
