Create a TreeNode class with the following methods: default constructor, two overloaded constructors, copy constructor, getValue, getLeft, getRight, setValue, setLeft, setRight b) Create a BTInterface with the following abstract methods: getRoot, setRoot, isEmpty, swapSubtrees, singleParent, preorder, postOrder, inOrder, insert c) Create an abstract Binary Tree class that implements the interface. Include the default constructor, a private helper method called checkNode for singleParent() and toString. Make insert an abstract method.

Poker card in PythonLet the CarteBase class present itself in the context of this exercise. It encapsulates a game card characterized by numerical values for its face and its kind. The possible faces are integers from 1 to 13, with face 1 corresponding to the ace, and faces 11, 12 and 13 corresponding respectively to the jack, the queen and the king. The other faces are simply identified by their number from 2 to 10. The possible grades are integers from 1 to 4 corresponding respectively to the cards of spade, heart, tile and clover. Analyze this class to understand how it works. You are asked to create a class called CarteDePoker that inherits CarteBase and defines or redefines the following methods: force(self) which returns the strength of the card in the poker game. In Poker, cards have the strength of their digital face from 2 to 13, except for the ace which is stronger than the other cards. So we give it a strength of 14.__eq__(self, other) to define operator behavior…

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.
