How to access data of nested objects in LinkedHashMap

Question

Data present in LinkedHashMap:-

{
    contacts={
        id={
            version=6,
            lastUpdatedTimeStamp=1377,
            contactID=23,
            firstName=B,
            lastName=K
        }
    }
}

Here, "contacts" & "id" are objects.

I am able to get the values of "contacts" :

LinkedHashMap map = restClient.getLinkedHashMap();
Object contactObj = map.get("contacts");

But how to get the value of "firstName"?

Any help or guidance will be well appreciated.

First share your contacts and id classes.

You should cast the contactObj to the class whose primitive you want to access. Ex, if your class for contactObj is Contact, then you should do:

Contact contactObj = (Contact) map.get("contacts");

and then you can access the methods/primitives in the class that are accessible from this point. Ex, say your class is like

Class Contact{
String firstname;
public String getFirstName(){
  return this.firstname;
   }
}

So, you can access the first name like as shown below:

contactObj.getFirstName();
