Create a Nested Structure in Java using a List Of Objects

Question

I have a following list of objects :-

    [
      {
      "tenantId": "ramyam101",
      "tenantName": "Level1-Tenant-OOUF",
      "parentName": "None",
      "tenantAccountType": "Organization-Only User Function",
      "index": 0,
      "tenantLogoBase64": ""
      },
      {
      "tenantId": "ramyam102",
      "tenantName": "Level2-Tenant-OOUF",
      "parentName": "Level1-Tenant-OOUF",
      "tenantAccountType": "Organization-Only User Function",
      "index": 1,
      "tenantLogoBase64": ""
      },
      {
      "tenantId": "ramyam103",
      "tenantName": "Level3-Tenant-OF",
      "parentName": "Level2-Tenant-OOUF",
      "tenantAccountType": "Organization Functional",
      "index": 2,
      "tenantLogoBase64": ""
      },
      {
      "tenantId": "ramyam104",
      "tenantName": "Level3-Tenant-OOUF",
      "parentName": "Level2-Tenant-OOUF",
      "tenantAccountType": "Organization-Only User Function",
      "index": 2,
      "tenantLogoBase64": ""
      }
    ]

This represents a hierarchy tree where each entry in the list has a 'tenantName' & 'parentName' and the level of the tenant in the hierarchy which is represented by 'index'.

For Example :-

                          Level1-Tenant-OOUF
                           |
               Level2-Tenant-OOUF
                 |           |   
    Level3-Tenant-OF     Level3-Tenant-OOUF

So I want to create a nested structure which has child node objects inside the parent object. How can I do this ? Please help me out...!

That is obviously [JSON](http://json.org/) format so use the [JSON API](http://www.oracle.com/technetwork/articles/java/json-1973242.html)!? :D — xander, Mar 28 '17 at 06:47
if You have a clear idea of the structure which is your model, you can use different libraries to parse this JSON, 1 min google search would get you there — Amer Qarabsa, Mar 28 '17 at 06:49
