I need a help to do a LinkedList class that implements OrderedListADT.

Question

public interface OrderedListADT <T> extends ListADT <T>
{
public void add (T element);
}

import java.util.Iterator;
public interface ListADT <T> extends Iterable <T>
{
public T removesFirst();
public T removesLast();
public T removes(T element);
public T first ();
public boolean contains(T target);
public boolean isEmpty ();
public int size ();
public Iterator <T> iterator ();
public String toString ();
}

Answer 1

Check the tutorial on Linked Lists. It has a java example too.
To implement the interface you need to define all of its methods.
