- 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_forwardcomplete the missing code. public class Exercise09_04Extra { public static void main(String[] args) { SimpleTime time = new SimpleTime(); time.hour = 2; time.minute = 3; time.second = 4; System.out.println("Hour: " + time.hour + " Minute: " + time.minute + " Second: " + time.second); } } class SimpleTime { // Complete the code to declare the data fields hour, // minute, and second of the int type }arrow_forwardArrays of objects. Java programming: How to create and work with an array of objects in Java I wanted to know that supppose that I have 100 employees who are paid on an hourly basis and I need to keep track of their arrival and departure times, and I have also created the class Clock to implement the time of day in a program. I also know that I will use two arraays; one called arrivalTime and the other array called departure time. Each of these arrays will have 100 elements and each element will be a reference variable of Clock type.. For example Clock[] arrival = new Clock[100]. My qeustion is how do I create the objects arrival and departure. Then how could I use the methods f the class clokc. Thank youarrow_forward
