java - 单链表最大键搜索

Question

我已经创建了这个 Node 类，我想找到具有最大键的节点并返回它:

class Node{
    int key;
    Node next;
    Node(int x){ key = x; next = null; 
    }
    int max = 0;


    Node findmax(Node h){
        if(h==null) return null;

        int max = 0;
        Node t= null;
        for(t=h; t!=null; t=t.next){
            if(t.next.key>t.key) max=t.next.key;
            t=t.next;
        }
        return t;
    }


    public static void main(String[] args){
        Node a = new Node(0);
        Node b = new Node(5);
        Node c = new Node(12);
        Node d = new Node(-12);
        Node e = new Node(124);
        Node f = new Node(2321);
        Node g = new Node(-231);

        findmax(a);

    }

}

知道为什么我不断收到此编译错误:

Node.java:34:错误:无法从静态上下文引用非静态方法 findmax(Node) findmax(a);

public Node findNode()
{   
    Node node = nodeList.getHead(); // get the head of the list
    Node prev = null;               // stores the previous node


    while(node != null)
    {   
        if(prev != null && prev.getKey() > node.getKey())
        {
            Node maxNode = prev;
        }

        // store node as prev and get the next node
        prev = node;
        node = node.getNext();
     }

return maxNode;

}
