Liferay 7.2 - How to user OrderByComparator?
Junior Member Posts: 81 Join Date: 6/25/19 Recent Posts
Hi,

I am getting my Journal Articles with the API:
JournalArticleLocalServiceUtil.getArticles(groupId, 0, 16);

But this is returning a list of Articles from the oldest to the newest. How should I use the OrderByComparator to order the Journal Articles from the newest to the oldest?

Thanks Mohammed!

I ended up with the following:
OrderByComparator<journalarticle> comparator = OrderByComparatorFactoryUtil.create("JournalArticle", "displayDate", "desc");</journalarticle>
