IN JAVA Please:
Implement a doubly linked list) The MyLinkedList class used in Listing 24.6
is a one-way directional linked list that enables one-way traversal of the list.
Modify the Node class to add the new data field name previous to refer to the
previous node in the list, as follows:
public class Node
E element;
Node
Node
public Node(E e) {
element = e;
}
}
Implement a new class named TwoWayLinkedList that uses a doubly
linked list to store elements. The MyLinkedList class in the text
extends MyAbstractList. Define TwoWayLinkedList to extend the
java.util.AbstractSequentialList class. You need to implement all the
methods defined in MyLinkedList as well as the methods listIterator()
and listIterator(int index). Both return an instance of java.util.
ListIterator
latter to the element at the specified index. Test using this code:
TEST USING THIS CODE:
USE PUBLIC CLASS EXERCISE2 for the name of the public class......
public class Exercise2{ public static void main(String[] args) { new Exercise2(); } public Exercise2() { TwoWayLinkedList list = new TwoWayLinkedList<>(); System.out.print("Enter 7 integers: "); Scanner input = new Scanner(System.in); double[] v = new double[5]; for (int i = 0; i < 5; i++) v[i] = input.nextDouble(); list.add(v[1]); list.add(v[2]); list.add(v[3]); list.add(v[4]); list.add(0, v[0]); list.add(2, 10.55); list.remove(3); java.util.ListIterator iterator1 = list.listIterator(); while (iterator1.hasNext()) System.out.print(iterator1.next() + " "); java.util.ListIterator iterator2 = list.listIterator(list.size() - 1); System.out.println(); while (iterator2.hasPrevious()) System.out.print(iterator2.previous() + " "); } public static class TwoWayLinkedList implements MyList { } public static interface MyList { } } correct answer that uses above code will be rated
please include sample run
HINT: The input for this test is
1 2 3 4 5
The expected output pattern is
1 2 3 4 5 5 4 3 2 1
