LinkedListExample.java
import java.util.LinkedList;

/*
 * Example of getFirst() and getLast() 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");

        /*
         * Returns the first element in this list.
         */

        Integer firstElement = linkedList.getFirst();
        System.out.println("firstElement :" + firstElement);

        /*
         * Returns the last element in this list.
         */

        Integer lastElement = linkedList.getLast();
        System.out.println("lastElement :" + lastElement);

    }

}

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

firstElement :200
lastElement :2000
