LinkedListExample.java
import java.util.LinkedList;

/*
 * Example of removeFirst() and removeLast() 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");

        /*
         * Removes and returns the first element from this list.
         */
        Integer removedFirstElement = linkedList.removeFirst();
        System.out.println("removedFirstElement : " + removedFirstElement);
        System.out.println("linkedList : " + linkedList + "\n");

        /*
         * Removes and returns the last element from this list.
         */
        Integer removedLastElement = linkedList.removeLast();
        System.out.println("removedLastElement : " + removedLastElement);
        System.out.println("linkedList : " + linkedList + "\n");

    }
}

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

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

removedLastElement : 2000
linkedList : [300, 10000, 5000]
