【剑指Offer】输入一个链表，按链表值从尾到头的顺序返回一个ArrayList (JAVA递归实现)

/**
*    public class ListNode {
*        int val;
*        ListNode next = null;
*
*        ListNode(int val) {
*            this.val = val;
*        }
*    }
*
*/
import java.util.ArrayList;
public class Solution {
    ArrayList<Integer> newArrayList=new ArrayList<Integer>();
    public ArrayList<Integer> printListFromTailToHead(ListNode listNode) {
        if(listNode!=null){
            this.printListFromTailToHead(listNode.next);
            newArrayList.add(listNode.val);
        }
        return newArrayList;
    }
}
