Sorting a list

[sivasiv]

Hi All,

I am trying to sort my list and i am getting following error: cannot find method sort(java.util.List<InquiryCommDTO>)

I am pasting my code below please help me in how to sort my communicationList.

private List<InquiryCommDTO> communicationList = new ArrayList<InquiryCommDTO>();

communicationList = inquiryDTO.getCommunications();

Collections.sort(communicationList);// i am getting the above mentioned error on this line.

Thanks a lot in advance.

Does InquiryCommDTO implements Comparable? If yes, please post an SSCCE that demonstrates the problem. If no, it must implement Comparable (see Comparable (Java Platform SE 6) )

Kindly format the code in your post. it's really annoying to read when unformatted.
