Java Syntax

Hi friend,


List interface :

* a List is a collection whose elements can be accessed by an index
* the indices are zero-based
* a list has methods for inserting and removing elements
* a list can contain duplicate elements
* a List provides a special ListIterator which allows you to move backwards and forwards through the elements
* there are three basic ways in which a List can be modified:
1. add an element
2. remove an element
3. replace an element
* a list can support any or none of the above; attempts to modify a list that does not support the above will result in an UnsupportedOperationException
* there is no way to append Lists unless you provide your own method

java.util Implementations of List :

It consists of ArrayList,LinkedList and Vector.

Your code is :

List values = new List();

List() constructor cannot be resolve :

So use List values = new ArrayList();
