Define a new class named BSTWithBFT that extends BST with the following method: public void breadthFirstTraversal()

This is for python class, so please answer in python   9.12 LAB: Product class   In main.py define the Product class that will manage product inventory. Product class has three attributes: a product code, the product's price, and the number count of product in inventory. Implement the following methods: A constructor with 3 parameters that sets all 3 attributes to the value in the 3 parameters set_code(self, code) - set the product code (i.e. SKU234) to parameter code get_code(self) - return the product code set_price(self, price) - set the price to parameter price get_price(self) - return the price set_count(self, count) - set the number of items in inventory to parameter count get_count(self) - return the count add_inventory(self, amt) - increase inventory by parameter amt sell_inventory(self, amt) - decrease inventory by parameter amt

Inheritance, Polymorphism, ArrayLists, Throwing Exceptions The UML diagram below shows a set of classes designed to represent a music collection from 1995. The constructors and methods all function in the standard way, except: The equipmentRequired method should return “Record Player” or “CD Player” as appropriate.The getAlbum method of the NinetiesMusicCollection class accepts an index and returns the corresponding Album object. This method throws an IllegalArgumentException if the index is out of range. (This is the only exception you have to throw anywhere in your code.)In the NinetiesMusicCollection constructor, you can assume the ArrayList<Album> object passed as an argument is not null . Don’t worry about privacy leaks.Implement this set of classes in Java. Note the italics on the Class name “Album” and the method name “equipmentRequired” in the Album class.

Lab 10 Using an interface to share methods It is often the case that two or more classes share a common set of methods. For programming purposes we might wish to treat the objects of those classes in a similar way by invoking some of their common routines.For example, the Dog and Cat classes listed below agree on the void method speak. Because Dog and Cat objects have the ability to “speak,” it is natural to think of putting both types of objects in an ArrayList and invoking speak on every object in the list. Is this possible? Certainly we could create an ArrayList of Dog that would hold all the Dog objects, but can we then add a Cat object to an ArrayList of Dog?Try running the main program below as it is written. Run it a second time after uncommenting the line that instantiates a Cat object and tries to add it to the ArrayList. import java.util.*;public class AnimalRunner{   public static void main(String[] args)   {      ArrayList<Dog> dogcatList = new ArrayList<Dog>();…

Create a fee invoice application for students attending Valence College, a college in the State of Florida. There are two types of students: graduate and undergraduate. Out-of-state undergraduate students pay twice the tuition of Florida-resident undergraduate students (all students pay the same health and id fees). A graduate student is either a PhD or a MS student. PhD students don't take any courses, but each has an advisor and a research subject. Each Ms and Phd student must be a teaching assistant for one undergraduate course. MS students can only take graduate courses. A course with a Course Number (crn) less than 5000 is considered an undergraduate course, and courses with a 5000 crn or higher are graduate courses.
