Usage of Collection classes sorting mechanism in a project

[Ravi Kiran Va]

Hi

I am having a query againist the usage of a Comparator or Comparable or Collection classes sort Mechanism in util package .

Can any body please tell me where actually this concept will be used in a project.
(What i think is that as the data from database will be returned by applying order by know )

Thank you .

great example:

if your data is coming from a database, i would prefer to do the sorting in the query itself rather than code unless
it involves user sorting a subset of data shown in UI, at that point i would use it in code.
