When a Random object does not have a seed value associated with it, what does it use instead?

StockList Class • This class will contain the methods necessary to display various information about the stock data. • This class shall be a subclass of ArrayList. • This class shall not contain any data fields. (You don't need them for this class if done correctly). • This class shall have a default constructor with no parameters. o No other constructors are allowed. • This class shall have the following public, non-static, methods: • printAllStocks: This method shall take no parameters and return nothing. ▪ This method should print each stock in the StockList to an output file. ▪ NOTE: This method shall NOT print the data to the console. The output file shall be called all_stock_data.txt. The data should be printed in a nice and easy to read format. o displayFirstTenStocks: This method shall take no parameters and return nothing. ▪ This method should display only the first 10 stocks in the StockList in a nice and easy to read format. ▪ This method should display the data in the...

A Random object will use whatever it finds as its seed value if you do not provide it with a seed value to use instead. Providing a seed value is optional.

Define a class called Book. This class should store attributes such as the title, ISBN number, author, edition, publisher, and year of publication. Provide get/set methods in this class to access these attributes. Define a class called Bookshelf, which contains the main method. This class should create a few book objects with distinct names and store them in an ArrayList. This class should then list the names of all books in the ArrayList. Enhance the program by providing a sort function, which will sort the books in ascending order of their year of publication. Create a few more Bookobjects with the same names but with different edition numbers, ISBNs, and years of publication. Add these new Book objects to the ArrayList, and display the book list sorted by book name; for duplicate books of the same name, sort the list by year of publication. (Hint: You will need to define a comparator class that takes two Book objects as parameters of the compareTo This method should do a two-step...

(PLEASE USE JAVA AND JFRAME GUI) Game rules:The game consists of a two-dimensional field of size m ×ばつ n (game field). Each element ofthe game field is a button with a number assigned to it.Initialization of the game:• The numbers on the buttons of the game field are set to a random digit between 0and 9• The target value is displayed above the game field• The current sum of the numbers displayed on the buttons of the game field is printedbelow the game field• The number of moves to completion is displayed in the upper right corner above thegame field.Playing:The first move is determined by the player by selecting any button (button A) on thegame field.1. The player is allowed to choose a second button (button B) located in the columnor row of the previously selected button (A).2. Upon selecting the second button (B), the value of button (A) is updated accordingto the following formula: A = (AoperationB)mod10.3. The operation for the basic game will be +.4. Decrement the number of moves...

In this project you will generate a poker hand containing five cards randomly selected from a deck of cards. The names of the cards are stored in a text string will be converted into an array. The array will be randomly sorted to "shuffle" the deck. Each time the user clicks a Deal button, the last five cards of the array will be removed, reducing the size of the deck size. When the size of the deck drops to zero, a new randomly sorted deck will be generated. A preview of the completed project with a randomly generated hand is shown in Figure 7-50.

Charge Account ValidationCreate a class with a method that accepts a charge account number as its argument. The method should determine whether the number is valid by comparing it to the following list of valid charge account numbers:5658845 4520125 7895122 8777541 8451277 13028508080152 4562555 5552012 5050552 7825877 12502551005231 6545231 3852085 7576651 7881200 4581002These numbers should be stored in an array. Use a sequential search to locate the number passed as an argument. If the number is in the array, the method should return true, indicating the number is valid. If the number is not in the array, the method should return false, indicating the number is invalid.Write a program that tests the class by asking the user to enter a charge account number. The program should display a message indicating whether the number is valid or invalid.

for the class ArrayAverage write a code that calculates the average of the listed numbers with a double result for the class ArrayAverageTester write a for each loop and print out the result
