java - Creating a generic object using a Class<?> variable -

i have generic class a, , i'm in method have create instance of based on class given object is. is, have:

public void (object obj) {   class<?> c = obj.getclass();   a<c> = ...; } 

however, on third line eclipse says c cannot resolved type. when remove generic parameter, "a raw type. references generic type should parameterized."

what correct way go here?

thanks.

public <c> void (object b) {   class<c> c = b.getclass();   a<c> = ...; } 

or better

public <c> void (c b) {   class<c> c = b.getclass();   a<c> = ...; } 

or if need class

public <c> void (class<c> clazz) {   a<c> = ...; }
