Question

How do I initialize the SortedMap? Really all I need is a series of strings that maintain the order in which they’re added to the series. I’m assuming SortedMap is even the best solution. BUT, every time I try to set cssFiles to an instance of Map() or SortedMap() I get nothing.

public class Controller {
    private SortedMap<Integer, String> cssFiles;
    private SortedMap<Integer, String> jsFiles;

    public Controller () {
        this.addCss("global.css");
        this.addJs("global.js");
    }
}

Seems you need a List (either ArrayList or LinkedList if you’re not into concurrency issues).

From the javadoc:

An ordered collection (also known as a sequence).
