Include instance variables, if it has public methods, and other classes if needed. Incude a test driver The ADT in this case is a Stack. Write the code for this stack. You are hired to help design software to help with a key train operation: processing food orders on a trip. Once the manager says that it is ok, train staff to walk from the back of the plane to the front taking everyone’s order. When they reach the front, they begin preparing those orders. Food orders are prepared in groups of 10, that being the number of cups that can fit onto a carrying tray. The first group whose food orders are prepared are those in the front of the plane (first class). The second group is the next 10 people further back in the plane and so on. You are in charge of developing a new application that will let train staff take food orders and then display those orders 10 at a…The following is a class definition of a linked list Node:class Node{int info;Node next;}Assume that Node's constructor receives no parameters.

Represent the tour as a circular linked list of nodes, one for each point in the tour. Each Node contains two references: one to the associated Point and the other to the next Node in the tour. Each constructor must take constant time. All instance methods must take time linear (or better) in the number of points currently in the tour. To represent a node, within Tour.java, define a nested class Node: private class Node { private Point p; private Node next; } Your Tour data type must implement the following API. You must not add public methods to the API; however, you may add private instance variables or methods (which are only accessible in the class in which they are declared). public class Tour // Creates an empty tour. public Tour() // Creates the 4-point tour a→b→c→d→a (for debugging). public Tour(Point a, Point b, Point c, Point d) // Returns the number of points in this tour. public…
