Re: ArrayList called with specific object constructors

That's clear, but I have problems using the interface Factory<T>

Also Robert code doesn't seem working because of course you can't
instantiate an interface:
List<Foo> lst = makeList(new Factory<Foo>() {
   Foo makeObject(String s1, String s2) {
     return new Foo(s1, s2);
   }

});

This is my code adapted with your suggestions:

//START
*** class calling generic method (implements Factory ?? Factory<T> ??)
***
....
ArrayList<Ric> ricList=xmlService.xml2objGEN(new Factory<Ric>());
....

*** class with GENERIC METHOD xml2objGEN() ***
....
private <T> ArrayList<T> xml2objGEN(Factory<T> factory){
        ArrayList<T> list=new ArrayList<T>();
        list.add(factory.makeObject("value1,"value2"));
        return list;
    }
*** interface Factory ***
public interface Factory<T> {
    public T makeObject(String s1, String s2);
}
//END

Thanks again,
Alessandro
