First, I searched for the problem, I didn't find. Then I looked at code and somewhere in the code, you comment your question, which is at all not attentive in any manner.
Second, if you posted the error that will yield more answer and error are sometime self explainable.

What type of objects does Collections.sort accepts ? Check the API.

hi,

java.util.Collections contains the following methods for sorting,

1)static void sort(List)
2)static void sort(List, Comparator)


from the above, we can see, the sort() method takes only argument of type List to sort. It does not sort HashSets.

and if you really want your set to be sorted one, try using java.util.TreeSet ;)
 
I agree. Here's the link: http://aspose.com/file-tools
