For anyone stumbling on this thread:

The following examples are modified for the sake of the gist, but the end solution is something like:

public enum ContentType {
    ARTICLE("article"),
    AUDIO("audio"),
    CARTOON("cartoon"),
    COMPETITION("competition");

    private String label;

    ContentTypeForm(String label) {
        this.label = label;
    }

    public String toString() {
        return label;
    }

    public String formPostData() {

        switch (this) {
            case ARTICLE:
                return createArticleFormPostData();
            case AUDIO:
                return createAudioFormPostData();
            case CARTOON:
                return createCartoonFormPostData();
            case COMPETITION:
                return createCompetitionFormPostData();
            default:
                throw new IllegalArgumentException("No such content type");

        }
    }
}

As Cucumber can use ENUMS as parameters, the usage follows:

@When("^I have launched a new \"([^\"]*)\" page$")
public void iHaveLaunchedANewPage(ContentType contentType) {
    String contentFormData = contentType.formPostData();
}
