java - How to make object return generic -

i looking @ following gson library provided google. in tutorial following have found following code snippet;

public class jsontojava {      public static void main(string[] args) throws ioexception {         try(reader reader = new inputstreamreader(jsontojava.class.getresourceasstream("/server1.json"), "utf-8")){             gson gson = new gsonbuilder().create();             person p = gson.fromjson(reader, person.class);             system.out.println(p);         }     } } 

is possible make generic, example, if have following parameters

public object getobjectfromjsonstring(string jsonstring, class classtype){ 

then know class type, possible return object type or have have individual methods, convertjsontoclassa, convertjsontoclassb, convertjsontoclassc , on?

this returns whatever generic type parameter of classtype is. if invoke class<string>, returns string, etc...

public <t> t getobjectfromjsonstring(string jsonstring, class<t> classtype) {     // code here } 

this implementation of gson#fromjson(string, class) does.
