- It is time for you to demonstrate your skills in a project of your own choice. You must DESIGN,ANALYSE AND CODE any method for the GENERIC MyLinkedList class that will manipulate the linkedlist. You can decide yourself what it should be following the specification below:1. Purpose: The method must make logical sense – it should be of some purpose to somebody.You should describe in the text who will use the method for which purpose.2. Clearly explain the problem. Then clearly explain how your method will solve it.3. Test program: Test the method using a wrapped class like Integer however, you will get extramarks if you can test it with the new classes you created in I_Do1 and I_Do2.It is time for you to demonstrate your skills in a project of your own choice.

- Write a java code to prepare a note for teaching your juniors on the topic of DFS in a Graph. (Main point: The output from your writen codes will be cosidered as the note the output should contain the notes about DFS in a graph with an example)You will implement some methods in the UndirectedGraph class. The UndirectedGraph class contains two nested classes, Vertex and Node, you should NOT change these classes. The graph will store a list of all the vertices in the graph. Each vertex has a pointer to its adjacent vertices. To get started, import the starter file, Undirected.java into the graphs package you create in a new Java Project. Please do not change any of the method signatures in the class, but you can add any helper methods you deem necessary. Implement the methods described below. You are free to test your code however you prefer. Vertex Class (DO NOT EDIT)The vertex class holds information about the vertices in the graph. It has an int val, a Vertex next that refers to the next vertex in the list of vertices (not necessarily an adjacent vertex), and a Node edge that starts the list of adjacent vertices. Node Class (DO NOT EDIT)This is a simple class to represent an adjacency list of a vertex in the graph.…Add comments for assignment p05Thanks! Run it with C, Linux

You will need to make the following changes: Your linked list should store information about Customers' Transactions that contain three fields: customer name (string), customer number (int), and transaction description (string). Instead of putting all of your code inside the main source code file, you should create the following functions: o addToStart(Item x) o addToEnd(Itemn x) o insertAt(Item x, int n) o remove(int customer number) o reverse() o printList() • Instead of simply asking the user if they want to add a new link, your main program should offer the user a menu of options: o Add a new link to the end o Add a new link to the beginning o Insert an element at index n into the list. 0 Remove a link from the list o Reverse the list o print out the entire list o Quit the programWrite a Java program that asks the user to enter items until the user chooses to stop, stores them into links (nodes), and chains the links together into a linked list.

- One use of a hash table is to implement a set data type. You will implement the methods addElement, find, toString, resize, and the MySetIterator inner class in the class MySet.
