/*
 * 
 * Example of addFirst(E e) and addLast(E e) methods
 */

public class LinkedListExample
{

    public static void main( String[] args )
    {
        LinkedList<Integer> linkedList = new LinkedList<Integer>();
        linkedList.add(200);
        linkedList.add(300);
        linkedList.add(10000);
        linkedList.add(5000);
        linkedList.add(2000);

        System.out.println("linkedList : " + linkedList + "\n");

        /*
         * Inserts the specified element at the beginning of this list.
         */
        linkedList.addFirst(90000);

        System.out.println("linkedList : " + linkedList + "\n");

        /*
         * Appends the specified element to the end of this list.
         */

        linkedList.addLast(80000);

        System.out.println("linkedList : " + linkedList + "\n");

    }

}

Output
linkedList : [200, 300, 10000, 5000, 2000]

linkedList : [90000, 200, 300, 10000, 5000, 2000]

linkedList : [90000, 200, 300, 10000, 5000, 2000, 80000]
