Create a public class Connections with a single public constructor that accepts a String. The String contains, in CSV format, a list of cities and other cities that they are connected to. So, for example, the input: Champaign,Chicago,St. Louis Chicago,Detroit,Milwaukee St. Louis,Champaign,Cincinnati Means that Champaign is connected to Chicago and St. Louis, and that Chicago is connected to Detroit and Milwaukee, and so on. Essentially the CSV serializes a directed graph, where the first item on each line is a node and the other items represent other nodes that it is connected to. This is one way of serializing a directed, unweighted graph. If the String passed to the constructor is null, throw an IllegalArgumentException. Make sure to trim all the Strings that you extract from the CSV. Your class should parse this String and provide a single instance method isConnected. isConnected accepts two Strings and returns true if the first city is connected to the second based on the graph passed to the constructor. So, given the input above, isConnected ("Champaign", "Chicago") would return true, but isConnected("Chicago", "Champaign") would return false. (Note that the graph is not necessarily symmetric.) If either String passed to isConnected is null, or if you don't have connection information for the source, you should throw an IllegalArgumentException. Note that only the cities that appear first on each line in the CSV should be treated as cities you have connection information for. So, for example, even though "Detroit" appears as a destination from "Chicago" in the data set above, we do not have a line starting with "Detroit", and therefore a call to isConnected with "Detroit" as the first parameter should throw an IllegalArgumentException.

-Interface IResearch Scholar has two methods public void teaches (String str) and public void studies (String str). - Define classes JuniorRS and SeniorRs such that JuniorRS implements IResearchScholar and SeniorRS extends JuniorRS. - Class InterAbstrTest extends SeniorRS, and has the main method. An object of JuniorRs invokes the method studies, and an object of SeniorRS invokes methods studies and teaches.

Lab 6 - Exercise 2. Write a test driver that reads data about two surgeons and print the specialization of the doctor with the highest salary using the method that compares the salary of surgeons. A Doctor class has the following private data members, constructor, and public methods: name (String) salary (int) End of document I A constructor without parameters, A constructor with parameters, A set method for the data variables (one method) A get method for each data members. A method to print Doctor information A Surgeon is a subclass of Doctor with the following private data members, constructor, and public methods: specialization (String) degree (string) A constructor without parameters, A constructor with parameters, · A set method for the data variables (one method) · A get method for each data member. · A method to print all Surgeon information. · A method that compares the salary of two Surgeons and return the specialization of the doctor with the higher salary. 1. Implement the…

Write a class named Library. A library has the following attributes:• name: the name of this library.• employees: a list of LibraryEmployees that work at the library.• books: a dictionary that contains Books as keys. The value paired with each key is either anempty string, or a string representing the name of a person who has checked out the Book.The Library class should have an initializer that MAY accept employees and books as arguments,but doesn’t have to do so. If provided, these values should be assigned to the object’srespective attributes. If not provided, employees and books should begin as an empty list anddictionary, respectively. The value for the name attribute is always provided.The class should also have the following methods:• hire_employee(): takes in a new LibraryEmployee, and adds it to this library’s list ofemployees.• add_book(): takes in a new Book, and adds it to this library’s books (unless the libraryalready has this book). If the library already has the book,…

In C++ Create a new project named lab8_1. You will be implementing two classes: A Book class, and a Bookshelf class. The Bookshelf has a Book object (actually 3 of them). You will be able to choose what Book to place in each Bookshelf.  Here are their UML diagrams  Book class UML Book - author  : string- title   : string- id      : int- count   : static int + Book()+ Book(string, string)+ setAuthor(string) : void+ setTitle(string) : void+ print() : void+ setID() : void And the Bookshelf class UML Bookshelf - book1 : Book- book2 : Book- book3 : Book + Bookshelf()+ Bookshelf(Book, Book, Book)+ setBook1(Book) : void+ setBook2(Book) : void+ setBook3(Book) : void+ print() : void Some additional information: The Book class also has two constructors, which again offer the option of declaring a Book object with an author and title, or using the default constructor to set the author and title later, via the setters . The Book class will have a static member variable…

shows the complete anagram.cpp program. Use a class to represent the word to be anagrammed. Member functions of the class allow the word to be displayed, anagrammed, and rotated. The main() routine gets a word from the user, creates a word object with this word as an argument to the constructor, and calls the anagram() member function to anagram the word.

Write a class definition line and a one line docstring for the class Dog. Write an __init__ method for the class Dog that gives each dog its own name and breed. Test this on a successful creation of a Dog object.>>> import dog>>> sugar = dog.Dog('Sugar', 'border collie')>>> sugar.name'Sugar'>>> sugar.breed'border collie' Add a data attribute tricks of type list to each Dog instance and initialize it in __init__ to the empty list. The user does not have to supply a list of tricks when constructing a Dog instance. Make sure that you test this successfully.>>> sugar.tricks[] Write a method teach as part of the class Dog. The method teach should add a passed string parameter to tricks and print a message that the dog knows the trick.>>> sugar.teach('frisbee')Sugar knows frisbee
