@quark @GoToLoop thks for your lights !
Et voilà the result:

void setup() {
}

int count = 0;
void draw() {
  count++;
  select_callback("my_method",this,"truc", count);
}

import java.lang.reflect.Method;
import java.lang.reflect.InvocationTargetException;
void select_callback(String callbackMethod, Object callbackObject, String s, int i) {
  try {
    Class<?> callbackClass = callbackObject.getClass();
    Method selectMethod =
    callbackClass.getMethod(callbackMethod, 
                            new Class[] { String.class, int.class });
                            
    selectMethod.invoke(callbackObject, s,i);
  } catch (IllegalAccessException iae) {
      System.err.println(callbackMethod + "() must be public");

  } catch (InvocationTargetException ite) {
      ite.printStackTrace();

  } catch (NoSuchMethodException nsme) {
      System.err.println(callbackMethod + "() could not be found");
    }
}

void my_method(String stuff, int value) {
  println(stuff,value);
}
