package demo.data;

import demo.data.pojo.Contact; import demo.tree.dynamic_tree.ContactTreeNode;

public class ContactList { public final static String Category = "Category"; public final static String Contact = "Contact";

private ContactTreeNode root;
public ContactList() {
    root = new ContactTreeNode(null,
        new ContactTreeNode[] {
            new ContactTreeNode(new Contact("Friend"),new ContactTreeNode[] {
                new ContactTreeNode(new Contact("High School"), new ContactTreeNode[] {
                    new ContactTreeNode(new Contact("Fernando Terrell", "Contact.png")),
                    new ContactTreeNode(new Contact("Stanley Larson", "Contact.png"))
                new ContactTreeNode(new Contact("University"), new ContactTreeNode[] {
                    new ContactTreeNode(new Contact("Camryn Breanna", "Contact.png")),
                    new ContactTreeNode(new Contact("Juliana Isabela","Contact-gu.png")),
                    new ContactTreeNode(new Contact("Holden Craig", "Contact-g.png"))
                new ContactTreeNode(new Contact("Emma Jones", "Contact-i.png")),
                new ContactTreeNode(new Contact("Eric Franklin",  "Contact.png")),
                new ContactTreeNode(new Contact("Alfred Wong", "Contact.png")),
                new ContactTreeNode(new Contact("Miguel Soto",  "Contact.png"))
            new ContactTreeNode(new Contact("Work"),new ContactTreeNode[] {
                new ContactTreeNode(new Contact("Andrew Willis",  "Contact.png")),
                new ContactTreeNode(new Contact("Russell Thomas",  "Contact-jq.png")),
                new ContactTreeNode(new Contact("Donovan Marcus",  "Contact.png"))
public ContactTreeNode getRoot() {
    return root;
