我想知道如何在java中创建自己的树，它由八个子节点组成，并且在每个子节点中它有许多子节点.如何创建这个.请帮我.我是 Java 新手.

I want to know how to create own tree in java, it consists of eight sub-nodes and in each sub-node it having many sub-nodes. How to create this. please help me. I am newer to java.

推荐答案

您可能需要创建某种 Node 类来表示树中的节点:

You'll probably need to create some sort of Node class to represent the nodes in the tree:

public class Node
{
    private List<Node> children = null;
    private String value;

    public Node(String value)
    {
        this.children = new ArrayList<>();
        this.value = value;
    }

    public void addChild(Node child)
    {
        children.add(child);
    }

}

然后填充您的树:

public static void main(String [] args)
{
    Node root = new Node("root");
    root.addChild(new Node("child1"));
    root.addChild(new Node("child2")); //etc.
}

您必须修改它以适合您自己的目的，此代码只是为了让您了解结构.

You'll have to modify this to suit your own purposes, this code is just to give you an idea of the structure.
