Thread: Java JSON question.

I use these online tools for a head start, google json to java online, they're not great but it's a start & once you already see some of the JSON in JAVA Objects it might save you some time in trying to figure out how to model your JSON in JAVA.

public class Pojo
{
    private String item;
 
    private List[] list;
 
    public String getItem ()
    {
        return item;
    }
 
    public void setItem (String item)
    {
        this.item = item;
    }
 
    public List[] getList ()
    {
        return list;
    }
 
    public void setList (List[] list)
    {
        this.list = list;
    }
}

Does this code makes sense to you? The model in your JSON is similar to a directory structure with folders containing files and other folders themselves containing containing files. It's a Tree model you're looking for.

--- Update ---

You could use something like this also I guess:

import java.util.ArrayList;
import java.util.HashMap;
 
public class ListObject {
    private ListObject parent = null;
    private ArrayList<String> items;
    static HashMap<ListObject, ArrayList<ListObject>> tree  = new HashMap<ListObject, ArrayList<ListObject>>();
 
    public ListObject(ListObject parent) {
    	this.parent = parent;
 
        if (this.parent != null) {
        	if (tree.get(parent) != null) {
        		tree.get(parent).add(this);
        	}
        	else{
        		ArrayList<ListObject> tempList = new ArrayList<ListObject>();
        		tempList.add(this);
        		if (1 != tempList.size())
        			tree.put(this, tempList);
        	}
        }
    } 
 
    public ArrayList<ListObject> getChildren(){
    	return tree.get(this);
    }
 
    public void addItem (String item) {
        if (this.items == null) items = new ArrayList<>();
        this.items.add(item);
    }
 
    public ArrayList<String> getItems () {
        return this.items;
    }
}
