import java.util.LinkedList;

/*
 * Example of offer(E e),offerFirst(E e) and offerLast(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");

        /*
         * Adds the specified element as the tail (last element) of this list.
         */
        boolean isAdded = linkedList.offer(4000);
        System.out.println("isAdded : "+ isAdded);
        System.out.println("After calling offer(4000) Method : linkedList : " + linkedList + "\n");
        
        /*
         * Inserts the specified element at the front of this list.
         */
        isAdded = linkedList.offerFirst(100);
        System.out.println("isAdded : "+ isAdded);
        System.out.println("After calling offerFirst(100) Method : linkedList : " + linkedList + "\n");

        /*
         * Inserts the specified element at the end of this list.
         */
        isAdded = linkedList.offerLast(6000);
        System.out.println("isAdded : "+ isAdded);
        System.out.println("After calling offerLast(6000) Method : linkedList : " + linkedList + "\n");

    }
}

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

isAdded : true
After calling offer(4000) Method : linkedList : [200, 300, 10000, 5000, 2000, 4000]

isAdded : true
After calling offerFirst(100) Method : linkedList : [100, 200, 300, 10000, 5000, 2000, 4000]

isAdded : true
After calling offerLast(6000) Method : linkedList : [100, 200, 300, 10000, 5000, 2000, 4000, 6000]
