- 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.arrow_forwardQuestion 13 What is outpout? public class Vehicle { public void drive(){ System.out.println("Driving vehicle"); } } public class Plane extends Vehicle { @Override public void drive(){ System.out.println("Flying plane"); } public static void main(String args[]) { Vehicle myVehicle= = new Plane(); myVehicle.drive(); } Driving vehicle syntax error Flying plane Driving vehicle Flying plane }arrow_forwardpublic class Accumulator { private int total private String name; public Accummulator (string name , int total) { this .name = name; this .total=total; } } 3.

- Sultan Qaboos University Department of Computer Science COMP2202: Fundamentals of Object Oriented Programming Assignment # 2 (Due 5 November 2022 @23:59) The purpose of this assignment is to practice with java classes and objects, and arrays. Create a NetBeans/IntelliJ project named HW2_YourId to develop a java program as explained below. Important: Apply good programming practices: 1- Provide comments in your code. 2- Provide a program design 3- Use meaningful variables and constant names. 4- Include your name, university id and section number as a comment at the beginning of your code. 5- Submit to Moodle the compressed file of your entire project (HW1_YourId). 1. Introduction: In crowded cities, it's very crucial to provide enough parking spaces for vehicles. These are usually multistory buildings where each floor is divided into rows and columns. Drivers can park their cars in exchange for some fees. A single floor can be modeled as a two-dimensional array of rows and columns.
