    Class MediaMerger This class is meant to host the main method used to test all the other classes in our project. We reccomend that you work on implementing the main method in this class progressively, as you add features to the other classes of this project. Do not attempt to implement all requirements for the main method before the other classes are able to be used in that manner. Work progressively, as demonstrated during the live coding videos in the...

    42) Create a toString method for the LinkedStack class. This method should create and return a string that correctly represents the current stack. Such a method could prove useful for testing and debugging the LinkedStack class and for testing and debugging applications that use the LinkedStack class. 46) Suppose we decide to add a new operation to our Stack ADT called sizeIs, which returns a value of primitive type int equal to the number of items on the stack. The...

    Data Structures - Singly Linked Lists You will add a method swapNodes to SinglyLinkedList class (below). This method should swap two nodes node1 and node2 (and not just their contents) given references only to node1 and node2. The new method should check if node1 and node2 are the same node, etc. Write the main method to test the swapNodes method. You may need to traverse the list. package linkedlists; public class SinglyLinkedList<E> implements Cloneable {    // ---------------- nested Node class...
