So you need to cast it to List<Student> first, before trying looping through it. RANT That is why I personally do not like var, it hides the type – unless in … Read more
Yes, you can use Python from the command line. python -c <stuff> will run <stuff> as Python code.

Instead of relying on Delphi’s internal object layout you could also have your objects implement another interface which would simply return the object. This, of course, only works if you have access to the source code of the objects to begin with, but you probably shouldn’t even use these hacks if you don’t have access … Read more

You can override validation error messages, inserting a line number, by using a custom ValidationEventHandler: package example; import javax.xml.bind.ValidationEvent; import javax.xml.bind.helpers.DefaultValidationEventHandler; public class MyValidationEventHandler extends DefaultValidationEventHandler { @Override public boolean handleEvent(ValidationEvent event) { if (event.getSeverity() == ValidationEvent.WARNING) { return super.handleEvent(event); } else { throw new RuntimeException(event.getMessage() + ” [line:”+event.getLocator().getLineNumber()+”]”); } } } If you configure … Read more
