Java Generics, Create an instance of Class<T> -

i trying write generic method deserializing json model. problem don't know how class generic type t. code looks (and doesn't compile way)

public class jsonhelper {      public <t> t deserialize(string json)     {         gson gson = new gson();          return gson.fromjson(json, class<t>);     } } 

i tried else, type, throws error had class jsonhelper<t> , tried this

class<t> persistentclass = (class<t>) ((parameterizedtype)getclass()     .getgenericsuperclass())     .getactualtypearguments()[0]; 

the method signature looks this

com.google.gson.gson.fromjson(string json, class<t> classoft) 

so, how can translate along t when call jsonhelper.deserialize<myobject>(json); instance of correct object?

you need class instance somewhere. is, deserialize() method needs take class<t> parameter, underlying fromjson() method.

your method signature should gson's:

<t> t deserialize(string json, class<t> type) ... 

your calls this:

myobject obj = helper.deserialize(json, myobject.class); 

by way, convention start method names lowercase letter established in java.
