Sort Java List by pubDate

I would like to sort a List of "Article" object by date.

My problem is that after sorting the list, it seems that the list is not well sorted.

Here is the code to sort the list :

public List<Article> getArticleList() {

    Collections.sort(articleList, new Comparator<Article>() {
        public int compare(Article o1, Article o2) {
            return o1.getPubDate().compareTo(o2.getPubDate());
        }
    });

    //Collections.reverse(articleList);

    for (Article a : articleList) {
        Log.d("RssHandler", "Date after sorting : " +a.getPubDate());
    }

    return articleList;
}

And here is the output :

It seems that getPubDate() returns a String. The natural order of Strings is to sort them alphabetically, which appears to be what is happening. Looking through your log, "F" comes before "M", "M" comes before "S", and so on, so, you are indeed getting a sorted list back of the Strings.

It would be better in your Article class to store Date objects (or Long timestamps). These will support sorting by date, which is what I assume you are after.
