How to sort RSS by date

So, if you’ve got one or more RSS feeds and you want to sort them according to the pubdate, do this:

Collections.sort(myFeedsList, new Comparator<RssItemModel>() {

            @Override
            public int compare(RssItemModel lhs, RssItemModel rhs) {
                SimpleDateFormat formatter = new SimpleDateFormat("EEE, dd MMM yyyy HH:mm:ss zzz");
                try {
                    Date date1 = formatter.parse(rhs.getPubDate());
                    Date date2 = formatter.parse(lhs.getPubDate());
                    return date1.compareTo(date2);
                } catch (ParseException e) {
                    e.printStackTrace();
                }
                return 0;
            }
        });

Android sorting an ArrayList

Title of my original article: How to sort an ArrayList in Java

Class Test {
public String name;
public String sirName;
}
ArrayList<Test> res = new ArrayList<Test>();
res.add(…);
res.add(…);
Comparator<Test> comperator = new Comparator<Test>() {
@Override
public int compare(Test object1, Test object2) {
return object1.name.compareToIgnoreCase(object2.name);
}
};
Collections.sort(res, comperator);
