1. Show the ListStackADT<T> interface 2. Create a ListStackDataStrucClass<T> with the following methods: defaultconstructor, overloaded constructor, copy constructor, getTop, setTop,isEmpty, ifEmpty (if empty throw the exception), push, peek, pop, toString. 3. Create a private inner class of ListStack<T> called StackNode<T> with thefollowing methods: default constructor, overloaded constructor, copyconstructor, getValue, getNext, setValue, setNext 4. Create a BaseConverter class (non-generic) with the following methods: defaultconstructor, inputPrompt, convert [converts a BaseNumber to a convertedString], convertAll [instantiate a String object] , toString, processAndPrint     5. Create a private inner class BaseNumber. The inner class has the following methods: default constructor, overloaded constructor, getNumber, getBase,setNumber, setBase. [Make your private instance variables in the inner classLong type]. 6. Create a BaseConverterDemo class that only…

Write a C++ a class definition for an abstract data type called Graph that models anundirected graph. Some implementation details: Create code for a .cpp file with main function and code for a .h file with classes • Loops are allowed but multiple edges are not allowed.• Vertices are labeled by number from 0 to n-1 where n is the number of vertices in thegraph.Implement the following public member functions.• A constructor that creates an empty graph.• An appropriate destructor.• void load(char *filename): Creates the graph using the file passed into thefunction. The format of the file is described later. You may assume load is only calledonce for a graph. • void display(): Displays the graph's adjacency matrix to the screen.• void displayDFS(int vertex): Displays the result of a depth first searchstarting at the provided vertex. When you have a choice between selecting two vertices,pick the vertex with the lower number.• void displayBFS(int vertex): Displays the result of a breadth…

15. Create an interface MessageEncoder that has a single abstract method encode (plainText), where plainText is the message to be encoded. The method will return the encoded message.

3.25 Fixed Sized Deque Your task is to create an implementation of the Java Deque interface that can only hold N items where N is a number passed into the constructor. Note that most (if not all) of the unit tests rely on the method object[] toArray() inherited from Collection. Therefore, you must make sure you implement that method correctly in order to get most of the points. 301664.1524810.gpazay7 LAB АCTIVITY 3.25.1: Fixed Sized Deque 0/ 70 Submission Instructions Compile command javac FixedsizedDeque.java -xlint:all -encoding utf-8 We will use this command to compile your code Upload your files below by dragging and dropping into the area or choosing a file on your hard drive.
