Charge Account Validation
Using Java programming
Create 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.

The program should have two Java classes: one for a single die and another for a pair of dice. Assignment Details: User Input: Ask the user to specify the number of sides they want on each die. Ensure that the user's input is within a reasonable range. Dice Rolling: Simulate rolling the dice using Math.random() based on the user's chosen number of sides. Display the sum of the values rolled, e.g., "5 + 3 = 8." Special Combinations: If the dice roll results in combinations of 2, 7, or 12, print special messages: "1 + 1 = 2 snake eyes!" "3 + 4 = 7 craps!" "6 + 6 = 12 box cars!" Main Method: In the main method, create a pair of dice, roll them, and display the results. Allow the user to decide whether to continue rolling the dice or exit the program. Additional Features: You are welcome to add more features or enhancements to the program if desired.…arrow_forward
- Topics Classes Methods Data Collections: Lists, Tuples, and Dictionaries String Manipulation Chess Objective: practicing with classes, instance methods, data collections, loops, if and elif statements, and string methods Description In this assignment you will write a program that shows the valid moves of chess pieces. Your program will draw a board with 64 squares using the traditional layout, next ask the user to choose a move, and then, depending on the user's choice, redraw the board with the selected chess piece and its valid moves. Please see the examples of valid moves of chess pieces and the traditional chess board layout below: At the beginning, your program should draw an empty chess board and prompt the user to enter a move: Welcome to the Chess Game! a b c d e f g h +---+---+---+---+---+---+---+---+8| | | | | | | | |8 +---+---+---+---+---+---+---+---+7| | | | | | | | |7 +---+---+---+---+---+---+---+---+6| | | | | |…arrow_forwardConsider the following pseudo code, Method func() { PRINT “This is recursive function" func() } Method main( { func() } What will happen when the above snippet is executed?arrow_forwardC++ language Write a menu driven program which has following options:1.

- Parking Charges Program in java Write a program that works out the amount a person has to pay for parking in a car park in a tourist town. If they say they are disabled, they are told it is free. Otherwise they enter the number of hours as a whole number (1-8) that they wish to park as well as whether they have an “I live locally” badge or are an old age pensioner both of which leads to a discount. The program tells them the cost to park. The calculation is done in this program as follows. If they are disabled it is free. Otherwise ... Take number of hours they wish to park and give a basic charge: • • • • 1 hour: 3.00 pounds 2-4 hours: 4.00 pounds 5-6 hours: 4.50 pounds 7-8 hours: 5.50 pounds Next modify the resulting charge based on whether they are local or not: • If local: subtract 1 pound If OAP: subtract 2 poundsYour program MUST include methods including ones that - asks for the hours and returns the basic charge. - asks whether they live locally /…arrow_forwardTreasure Hunter description You are in front of a cave that has treasures.
