LeetCode 237 -Delete Node in a Linked List ( JAVA )

Write a function to delete a node (except the tail) in a singly linked list, given only access to that node.

Supposed the linked list is 1 -> 2 -> 3 -> 4 and you are given the third node with value 3, the linked list should become 1 -> 2 -> 4 after calling your function.

/**
 * Definition for singly-linked list.
 * public class ListNode {
 *     int val;
 *     ListNode next;
 *     ListNode(int x) { val = x; }
 * }
 */
public class Solution {
    public void deleteNode(ListNode node) {
        if(node.next == null){
            return;
        }else{
            node.val=node.next.val;
            node.next=node.next.next;
        }
    }
}

总结：仔细读题目，其实我第一次没读懂- -，看了别人的才反应过来，题目的意思是，有一个单链表，给你一个链表内的节点，让你把这个节点删掉，那就删好咯- -，很简单。
