A good design will be : Create a class RootNode with array of eight references to another class FirstLevelChildNode which in turn has dynamic array (say ArrayList) of another class ChildNodes, with required operations in each class...
一个好的设计是：创建一个 RootNode 类，其中包含对另一个类 FirstLevelChildNode 的八个引用的数组，该类又具有另一个类 ChildNodes 的动态数组（比如 ArrayList），每个类中都有所需的操作......

You'll probably need to create some sort of Node class to represent the nodes in the tree:
您可能需要创建某种 Node 类来表示树中的节点：
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);
}
}
Then to populate your tree:
然后填充你的树：
public static void main(String [] args)
{
Node root = new Node("root");
root.addChild(new Node("child1"));
root.addChild(new Node("child2")); //etc.
}
You'll have to modify this to suit your own purposes, this code is just to give you an idea of the structure.
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。
