Edit Question
Title
Body
I have a handful of helper methods that convert enum values into a list of strings suitable for display by an HTML <select> element. I was wondering if it's possible to refactor these into a single polymorphic method. This is an example of one of my existing methods: /** * Gets the list of available colours. * * @return the list of available colours */ public static List<String> getColours() { List<String> colours = new ArrayList<String>(); for (Colour colour : Colour.values()) { colours.add(colour.getDisplayValue()); } return colours; } I'm still pretty new to Java generics, so I'm not sure how to pass a generic enum to the method and have that used within the for loop as well. Note that I know that the enums in question will all have that getDisplayValue method, but unfortunately they don't share a common type that defines it (and I can't introduce one), so I guess that will have to be accessed reflectively...? Thanks in advance for any help.
