Chapter 2, Problem 28C
Write a set of Java classes that can simulate an Internet application in which one party, Alice, is periodically creating a set of packets that she wants to send to Bob. An Internet process is continually checking if Alice has any packets to send, and if so, it delivers them to Bob’s computer; Bob is periodically checking if his computer has a packet from Alice, and if so, he reads and deletes it.

JAVA Programming:
After Elon Musk decided to make a new business idea. He found a social network called
"Friends.com". It has currently N registered users. Likewise in any social network many users
can be friends. Elon Musk wants the world to be as super connected as possible, so he has
this new way to suggest friendship to some pairs of users. He suggests user u to have a
friendship with user v if they are not friends yet and there is a user w who is friends of both
of them. Note that u, v and w are different users. Elon Musk is too busy with SpaceX these
days, so he hired you to develop a JAVA program to count out how many friendship
suggestions he has to send over his social network "Friends.com".

Write a java program that simulates a vending machine. Products can be purchased by inserting coins with a value at least equal to the cost of the product. A user select a product from a list of available products, add coins, and either gets the products or gets the coins returned. The coins are returned if insufficient money was supplied or if the product it's sold out. The machine does not give change if too much money was added. Products can be restocked and money remove by an operator. Your solution should include a class VendingMachine that is not coupled with the Scanner or PrintStream classes.
PS: For the VendingMachine.java, using public ArrayList<Product> getProductList(){ ArrayList<Product> list = new ArrayList<>();}
instead of public ArrayList<String> getProductList(){ ArrayList<String> list = new ArrayList<String>();}

- Write a java programImagine a publishing company that markets both book and audiocassette versions of its work. Create a class publication that stores the title (a string) and price(type float) of a publication. From this class derive 2 classes: book, which adds a page count (type int); and tape, which adds a playing time in minutes (type float). Each of theses 3 classes should have a getdata() method to get its data from the user at the keyboard, and a putdata() function to display its data. Suppose you want to add the date of publication for both books and tapes. From the publication class, derive a new class called publication2 that includes this data member. Then change book and tape so ther are derived from publication2 instead of publication. Make all the necessary changes in member functions so the user can input and output dates along with the other data. For the dates, you can use the bulit-in date function which stores a date as 3 ints, for months, day and year.

Then, the user is prompted to guess letters in the word one at a time. When the user makes a correct guess, all instances of that letter in the word are shown. When all letters in the word have been guessed, the game ends and the score (number of missed guesses) is displayed. A user can play the game multiple times if they choose. Here is a sample run of a correct program (user input indicated by orange text):Enter a letter in word ******** > cEnter a letter in word c******* > rEnter a letter in word c******r > s s is not in the wordEnter a letter in word c******r > tEnter a letter in word c****t*r > mEnter a letter in word c*m**t*r > t t is already in the wordEnter a letter in word c*m**t*r > pEnter a letter in word c*mp*t*r > oEnter a letter in word comp*t*r > eEnter a letter in word comp*ter >…arrow_forwardWrite a Java procedural program that helps organise travellers with a specific travel company arriving at an airport, telling them which queue to join based on their hotel. The program asks each traveller what their hotel is (the choices are the Seaview for which they need to join Queue 1, the Majestic for which they need to join Queue 4 and the Grand for which they need to join Queue 7) and tells them the right queue. There are 1330 travellers with the tour company and each will use the program as they arrive. After all have indicated their hotel, the program then prints the percentage in each hotel. * See image for an example run of the program. Percentages should be printed truncated to two decimal places. Do this using a method you write yourself that multiplies by 100, converts to an integer then divides by 100. * must make use of a counter-controlled for loop, be in procedural programming style (not OOP)arrow_forward

In this game, each card has a value from 1..10 inclusive. There are 4 of each value in the deck, i.e., 40 cards in total. Cards are not replaced in the deck once drawn, i.e., no more than 4 of each value will be drawn. The program starts by asking the player for a target score. The game proceeds in a series of rounds with the program repeatedly drawing and showing a card from the deck to the player one at a time. Each time, it asks the player to enter "h" (higher) or "l" (lower) to guess whether the next card drawn will be higher or lower in value. The player gains a point if they guess correctly. The game continues until the player guesses incorrectly or the target score is reached. When the game ends, it prints either a "You win!" or a "Nice try, you scored …” message as illustrated below.

- UOWD Library is asking you to write a Java program that manages all the items in the Library. The library has books, journals, and media (DVD for example). All items have a name, author(s), and year of publication. A journal also has a volume number, while a media has a type (audio/video/interactive). The user of your program should be able to add an item, delete an item, change information of an item, list all items in a specific category (book, journal, or media), and print all items (from all categories). A menu asks the user which operation s/he wants to perform. Important: make use of collections, inheritance, interfaces, and exception handling wherever appropriate.arrow_forwardJava Programming (no copy-pastes, please) In Java, write two applications, a client and a server that communicate with each other according to the protocol: The connection is only maintained (authenticated) if the first thing the client sends is the message “OOP”; After the first authentication, the server will receive messages typed in by the client until he sends an “End” message; the server will just write the received messages on the screen; When the server receives the “End” message, it will start sending typed messages to the client, who will receive them and write them to the screen until an “End” message is sent to the client.arrow_forwardWrite a program in java Design a class that holds the following personal data: name, address, age, and phone number.Write appropriate accessor and mutator methods.
