Question

I have this test method:

public void load(Class<? extends Object> className, XXXX)
{
  Criteria criteria = session.createCriteria(className);
  List<Object> list = criteria.list();

  for (Object item : list)
  {
    list.add(new Object(item.getId, item.getCode); /* Object doesn't know getId */
  }
}

How to replace XXXX in load method to call it using concrete Object? Something like:

load(Foo.class, testObject)

Is it possible?

Answer 1

Every generic type must extend Object, so this is sufficient:

public <T> void load(Class<T> className, T object)
{
    // snip...
}
