Question

I have the following code that is used in the Image gallery generating program Jalbum to generate all keywords used for the images in the gallery.

Set allKeywords = new HashSet();
for (AlbumObject ao : currentObjects) {
   XmpManager mgr = ao.getXmpManager();
   if (mgr != null) {
      allKeywords.addAll(mgr.getKeywordSet());
   }
}
//get the Iterator
Iterator itr = allKeywords.iterator(); 
while(itr.hasNext())
   out.println(itr.next());

My question is when out.print:

out.println(itr.next());

how can I add html to each individual keyword? I basically want to outprint:

<a href="#">keyword</a>

I am a newbie in this realm so please be gentle!

Answer 1

out.println("<a href=\"#\">" + itr.next() + "</a>");

If you want to call iterator.next() two times

out.println("<a href=\"#\" class=\"label list2\""
                + " data-filter=\"" + "." + itr.next() + "\">"
                + (itr.hasNext() ? itr.next() : "") + "</a>");

For your requirement I hope mgr.getKeywordSet() returns string

  String str = itr.next();
  System.out.println("<a href=\"#\" class=\"label list2\""
                + " data-filter=\"" + "." + str + "\">" + str + "</a>");
