Question

How is it possible to declare an object of type option in Java? I was told that the following code would convert a Vector of Strings into a Vector of Option, but new Option(String) is not a valid constructor:

private <T> Vector<Option> convertToOptions( Vector<T> convert )
{
     Vector<Option> options = new Vector<Option>();
     for ( T temp : convert )
          options.add( new Option( temp.toString() ) );
     return options;
}

It looks like you might need to create an AttributeSet and then convert it to an Option? Something like this…

SimpleAttributeSet set = new SimpleAttributeSet();
for ( T temp : convert ){
    set.add(temp.getName(),temp.getValue());
    }
Option option = new Option(set);

Otherwise, if you’re creating a dropdown, are you using JComboBox? If so, this has a JComboBox(Vector) constructor – might be much easier. Otherwise, what class are you using to create the dropdown?
