Question

add a copy construction to the class on the program. it should create a deep copy. class C15e6 { public static void main(String[] args) { MyLinkedListL6 list = new MyLinkedListL6(); list.addFirst(1); list.addFirst(2); list.addFirst(3); System.out.println("Numbers on list"); list.traverse(); } } //============================================== class MyLinkedListL6 { private class Node { private Node link; private int x; } //---------------------------------- private Node first = null; //---------------------------------- public void addFirst(int d) { Node newNode = new Node(); newNode.x = d; newNode.link = first; first = newNode; } //---------------------------------- public void traverse() { Node p = first; while (p != null) { System.out.println(p.x); p = p.link; } } }
