如何删除链表java中的所有事件

public class ListNode {
    int val;
    ListNode next;

    ListNode(int val) {
        this.val = val;
    }
}

public class LinkedListUtils {
    public static ListNode deleteLinkedList(ListNode head) {
        ListNode current = head;
        while (current != null) {
            ListNode next = current.next;
            current.next = null;
            current = next;
        }
        return head;
    }
}

// 示例用法
ListNode head = new ListNode(1);
head.next = new ListNode(2);
head.next.next = new ListNode(3);

ListNode result = LinkedListUtils.deleteLinkedList(head);
