Sorted & Ordered

[Shalini Banerjee]

I do not understand what is ment by sorted & ordered of elements.
I am asking the question from Collection Topics.

can any body explain what is the difference between them with example.

thnx in advance.

When a collection is said to be ordered if it can be iterated in a specific order.
Ex: ArrayList, but a Hashtable is not.

When a collection is said to be sorted if the values in it is sorted in a natural order. So when you are retriving the vaues you get it in sorted order. A sorted collection is also Ordered ..
ex: Treeset

when you are using the ArrayList and the elements are retrieved in the order in which they are inserted into the list.(ordered but not sorted)

When you use a TreeSet you will have the elements in the specific order
(Eg:Integer objects are sorted in ascending), or in the way you specify

So sorted also means some type of ordering.
But ordering doesnot assure to be sorted.
