generics - Using raw type with interface in Java -

i'm trying find information raw types , possible use interface following way:

public class globalconverter {      public interface listener {         void onready(object t);     }      public void convert(string string, class<?> resultclass, listener listener) {         try {             listener.onready(resultclass.newinstance());         } catch (illegalaccessexception e) {         } catch (instantiationexception e) {         }     }      public void test() {         convert("test", myclass.class, new listener() {              @override             public void onready(object object /* possible myclass object ? */) {             }         });     } } 

what i'm trying achieve above, end user onready callback return resultclass type of object. hints/explanations highly appreciated.

thanks.

i'll make listener generic:

public interface listener<t> {     void onready(t t); } 

and convert method should generic:

public <t> void convert(string string, class<t> resultclass, listener<t> listener) {     try {         listener.onready(resultclass.newinstance());     } catch (illegalaccessexception e) {     } catch (instantiationexception e) {     } } 

and call like:

convert("test", myclass.class, new listener<myclass>() {         @override         public void onready(myclass object) {         }     });
