Question

Hey, I was wondering if anyone could help me with a jave program exercise from the book "Big Jave Late Object"

Here it is:
P.16.10 Add a method boolean contains(Object obj) that checks whether our LinkedList implementation contains a given object. Implement this method by directly traversing the links, not by using an iterator. Also please include comments in the program and a tester for the program.

Thank you.

Solution:

LinkedListDemo.java:

import java.util.*;
class LinkedListDemo {
   public static void main(String[] args) {
       LinkedList<Integer> list = new LinkedList<Integer>();
       list.add(1);
       list.add(2);
       list.add(3);
       list.add(4);
       list.add(5);
       System.out.println("Linked List is: "+list);
       System.out.println("The List contains the object : "+list.contains(3));
   }
}
output:
