Passing a class (“Country.class”) as an argument in Java

Question

All the po

Answer 1

I think you want to do

private long countModel(Class<? extends Model> clazz) throws SecurityException, NoSuchMethodException, IllegalArgumentException, IllegalAccessException, InvocationTargetException
{
  Method countMethod =  clazz.getDeclaredMethod("count", null);
  return (Long) countMethod.invoke(null, null);
}

Hopefully something like this would work (my reflection skills are not really that good).
