For your first program, you are to write a simple Dodgeball simulation. In this simulation, we will have nplayers, and one ball. One player, the "thrower," will have the ball. The thrower will throw the ball at anotherplayer, the "target." The target could catch the ball, could be hit by the ball, or the ball could completely missthe target. If the target catches the ball, then the thrower is out of the game (and the target becomes the nextthrower.) If the ball hits the target, then the target is out of the game. If the ball misses the target, neitherplayer is out. In the latter two cases, any one can pick up the ball and become the next thrower. The game isover when only one player is left.In this simple version, the players (initially n players) will stand in a circle. The thrower will always countthe players to his/her right, and then throw the ball at the dth player, who becomes the target. The target willalways catch the ball, so that the thrower will be out of the game (and will…
In this task, you will create your own interface, which is not provided in the Java library. Let’s start with a simple example.
Say we have a collection of animal classes, with each class represents a kind of animal. They all share a common ability of “speak”. Dog speak in the way of “Woof! Woof!”, cats speak in the way of “Meow! Meow!”, etc. In order to capture this common characteristic, we need an interface named Speakable:
public interface Speakable
{
// put the method header here
}
Think about what method is needed for the Speakable interface? (what method can describe the speakable feature? )
We simply need one method speak() to print out the way that the animal “speaks”. Put the method header in the interface body. This method does not take any parameter and does not return any value.
Be reminded that you only need to put the method header with a semicolon (abstract method) into the interface.
BE NOTED: Adding an interface is different from adding a class. You need to click File…
Your task is to implement the Name class. This class represents a person's name. It has three instance variables representing the first, last and middle name (all are string variables). A character instance variable representing a separator (to be used for printing purposes) is also part of the class. The only valid separators we can have are a comma (,), a dash (-), and a pound symbol (#). In addition, a nickname instance variable (string) keeps track of the person's nickname (if any). The output have to match with the image I provided. Please don’t use chegg solution, need a different coding style. Write code in JavaScript

See Programming Project 8.7 (PP 8.7) from page 403 of your textbook (or view the attached image) for a description of what your program needs to do. Note that although the book description of the problem states that you should write the Card class, I do not want you to do that.

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_forwardWhen you add a contact to your phone, it automatically sorts those names alphabetically. In this exercise, we are going to create a phonebook that automatically sorts everytime a new number is added to the phonebook. A PhoneNumber class has been created already that has the instance variables name and number. Your job is to create the PhoneBook class that will store an ArrayList of PhoneNumbers. The PhoneBook class does not have a constructor - it only contains an ArrayList that can store the individual phone numbers that are added to it. There should be three methods in the PhoneBook class: addNumber- This method takes a PhoneNumber and adds it to the directory. Once the number has been added, the sort method is called on the directory to sort that new address into the phone book. sort- This method sorts the directory in alphabetical order A-Z.a. Remember that in order to compare Strings, we can use the compareTo() method. This returns an integer that indicates whether a String’s…arrow_forward

Book objects should be ordered by rating, and then (if the ratings are equal) they should be ordered alphabetically by title.
