How to sort an arraylist?

[sridevi kumar]

Hi:
I want to sort an array list (project requirement)? Could anyone guide me how to do this?
Thanks a lot...

Collections.sort() is a simple and easy way to do that. But remember that the object being sorted must implement Comparable.

Thanks a lot Greg Barish.
Could u please tell me how to implement Comparable to sort the strings?
Thanks a lot again

The comparable interface declares one method called compareTo(). It returns -1,0, or 1 depending whether the current object is less than, equal to or greater than the one passed to the method. Check the API for more details.

BTW, Strings already implement Comparable, so you really don't need to do anything. Just stick the String objects in your ArrayList and call Collections.sort().
