LinkedList的反转

Answer 1

LinkedList没有提供反转链表的相关函数，以下是通过foreach实现链表反转

static LinkedList reverseLinkedList(LinkedList linkedList) {
    LinkedList<Object> newLinkedList = new LinkedList<>();
    for (Object object : linkedList) {
        newLinkedList.add(0, object);
    }
    return newLinkedList;
}
