Leetcode: Delete Node in a Linked List

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.

public class Solution {
public void deleteNode(ListNode node) {
if(node != null && node.next != null) {
node.val = node.next.val;
node.next = node.next.next;
}
}
}
